Cyclone Yaas

Very Severe Cyclonic Storm Yaas was a powerful that formed as a depression over the east-central on 23 May 2021, intensifying rapidly into a very severe cyclonic with sustained winds reaching 75 knots before making landfall near in , , around midday on 26 May. The tracked north-northwestward, dissipating over inland by 27 May after generating surges of 2-4 meters above astronomical tide along north coastal , heavy rainfall exceeding 200 mm in affected districts, and gusts up to 120-140 km/h near the coast. Primarily impacting and states in , as well as coastal , Yaas caused widespread infrastructure damage including inundation of low-lying areas, uprooting of trees, and disruption to power and communications, though fatalities remained low at around six due to large-scale evacuations of over one million people. Economic losses were estimated in billions of rupees, particularly from crop destruction and housing damage in , marking it as one of the stronger May cyclones in the region since 1965.

Meteorological History

Formation and Early Development

A formed over the east-central during the morning of 22 May 2021 (0300 UTC), associated with a weakening extending from the . By the morning of 23 May, it had organized into a well-marked , supported by sea surface temperatures around 30–31°C across much of the , which provided favorable energy for development. The system intensified into a over the east-central that evening (1200 UTC 23 May), with the (IMD) estimating initial sustained winds of approximately 35–45 km/h. The (JTWC) had issued a Tropical Cyclone Formation Alert for the disturbance earlier on 22 May at 1500 UTC, noting potential for further organization under moderate vertical wind shear and upper-level divergence. These atmospheric conditions, including good outflow aloft, facilitated the early structuring of around the low-level circulation center. By 24 May, the depression strengthened into a cyclonic storm, designated Yaas by the IMD, with sustained winds reaching 65–75 km/h (3-minute mean) as observed in satellite imagery and scatterometer data. The cyclone tracked northwestward during this initial phase, embedded within a steering environment influenced by a mid-level ridge to the north.

Intensification and Landfall

Cyclone Yaas intensified into a severe cyclonic storm over the west-central by 2330 IST on 24 May 2021, with maximum sustained winds reaching approximately 90-100 km/h. Further strengthening occurred amid low vertical and high , enabling the system to escalate to very severe cyclonic storm status by 1730 IST on 25 May, featuring sustained winds of 130-140 km/h gusting to 155 km/h. observations during this phase revealed a well-defined eye, indicative of organized convection and favorable environmental conditions for . The cyclone's track shifted northeastward under the influence of steering currents associated with a subtropical ridge, directing it toward the Odisha-West Bengal coast. Peak intensity was attained early on 26 May 2021, with estimated maximum sustained winds of 75 knots (139 km/h) and a central pressure around 966 . Landfall occurred near 21.35°N, 86.95°E, approximately 20 km south of in , between 1030 and 1130 IST on 26 May, as a very severe cyclonic with winds of 130-140 km/h. This timing coincided with perigean spring tides, which amplified the potential impact along the shallow coastal waters.

Dissipation and Remnants

After making landfall near , , Cyclone Yaas rapidly weakened over land, transitioning from a very severe cyclonic storm to a severe cyclonic storm by 0900 UTC on 26 May 2021, a cyclonic storm by 1200 UTC, and a by 1800 UTC over north interior and adjoining south . The system moved north-northwestwards initially, then northwestwards across into , with continued weakening to a centered over central by 0600 UTC on 27 May. The remnant deep depression tracked into , producing heavy to extremely heavy rainfall in on 26–27 May, including 210 mm at Chaibasa and 150 mm at on 27 May, and in on 27–29 May, with up to 250 mm recorded at Manihari and 210 mm at Purnea on 28 May. By 0000 UTC on 28 May, it had diminished to a well-marked over and adjoining southeast , further weakening to a by 1200 UTC that day. The remnants became less marked by 0000 UTC on 29 May 2021 over , effectively dissipating as a distinct system, with residual moisture contributing to ongoing precipitation patterns in the region.

Preparations and Forecasting

Warnings and Predictions

The (IMD) initiated monitoring of a over the southeastern and on May 13, 2021, approximately nine days before the system's intensification into a . Fishermen warnings were issued starting May 23, advising against venturing into the sea until further notice due to anticipated cyclonic circulation. The first formal cyclone bulletin was released at 1350 IST on May 23, forecasting the depression to develop into a cyclonic storm within 24-48 hours and move north-northwestwards. Warnings escalated on May 24, with IMD predicting intensification into a severe cyclonic storm and potential very severe status, issuing specific cyclone alerts for the - coasts at 2030 IST. By May 25, bulletins specified between Paradip () and Sagar Islands () around noon on May 26 as a very severe cyclonic storm with wind speeds up to 150-160 km/h gusting to 185 km/h. Track forecasts remained consistent, with the actual near , , falling within the predicted 200-300 km radius, demonstrating reasonable accuracy in , , timing, and point of crossing. The (JTWC) designated the system as 02B on May 24, forecasting intensification to Category 1 hurricane-equivalent (1-minute sustained winds of 64-82 kt) prior to , aligning closely with multi-model but estimating slightly lower than IMD's 3-minute sustained winds of 140 km/h. Some global models, including ECMWF, exhibited variability in projections due to uncertainties in vertical , which ultimately decreased to favor rapid deepening, leading to minor underpredictions of strength in certain ensembles. Despite the ongoing potentially straining dissemination resources, IMD's verifiable track guidance, updated hourly via round-the-clock surveillance, supported pre- alert timelines.

Evacuation and Mitigation in India

Authorities in and initiated large-scale evacuations ahead of Yaas's on May 26, 2021, moving approximately 600,000 people from vulnerable coastal areas in and over 800,000 in to safer locations. These efforts prioritized districts such as , , and in , as well as South and North in , where risks were highest. In , over 6,600 temporary shelters were established alongside 890 permanent cyclone shelters, many of which had been constructed or upgraded following lessons from previous cyclones like Phailin in 2013. prepared more than 14,000 relief camps across affected districts to accommodate evacuees. The (NDRF) deployed 109 teams, including 44 in and 32 in , positioned for rapid response in coastal zones. Mitigation measures included preemptive shutdowns of key infrastructure: Kolkata's Netaji Subhas Chandra Bose International Airport was closed for 18 hours from May 26 to May 27, while Bhubaneswar's International Airport suspended operations from 11:00 PM on May 25 until 5:00 AM on May 27. services were halted on approximately 350 trains affecting eastern , and power authorities implemented selective disconnections in high-risk areas to prevent hazards from fallen lines. The Union Power Ministry prepositioned transformers and generators to address anticipated outages.

Responses in Bangladesh and Neighboring Areas

In , authorities prepared 6,816 cyclone shelters across coastal districts and deployed 1,343 emergency medical teams in anticipation of heavy rainfall, surges of 3 to 4 feet, and potential inundation in 14 to 16 low-lying areas, including districts like and . Ports were instructed to hoist distant warning signal number two, signaling caution for squally weather and rough seas. Evacuations were facilitated by local cyclone preparedness programs, , fire services, police, and armed forces, though the cyclone's peripheral effects limited the scale compared to direct zones. In , the Department of Meteorology issued warnings for fishermen and naval communities, advising against sea voyages due to expected strong winds of 70-80 kmph (with gusts up to 90-100 kmph) and sudden swells in the and southeastern seas. A was declared for heavy rains and gale-force winds, particularly affecting southern coasts, but no large-scale evacuations occurred as the storm's track veered eastward away from the island's core. International organizations, including the (IOM), prepositioned resources in Bangladesh's vulnerable coastal and refugee-hosting areas like , focusing on monsoon-season contingencies amid forecasts of peripheral winds up to 80 kmph and compounded risks from ongoing restrictions. These measures emphasized early warnings and shelter readiness rather than extensive relocation, given the cyclone's primary trajectory toward .

Impacts

Meteorological Effects

Cyclone Yaas generated sustained wind speeds of 130–140 km/h with gusts reaching 155 km/h along and off the coasts of and districts in northern during landfall on May 26, 2021. These winds diminished rapidly inland but remained gale-force (63–87 km/h) over adjacent areas of . The system delivered heavy rainfall across and , with 24-hour accumulations typically ranging from 100 to 250 mm in coastal and northern districts. Isolated maxima exceeded 300 mm, including 304 mm recorded at Kusumi in , . Cumulative totals over the event reached up to 800 mm in some locations, such as Chandbali. A of 2–4 meters above astronomical levels inundated low-lying coastal areas of northern , exacerbated by the timing of during spring tides. Surge heights were higher near the landfall point, with observations indicating variations up to 4 meters in and districts.

Human and Casualty Toll

Cyclone Yaas resulted in at least 20 confirmed fatalities across and , with the majority attributed to incidents and falling s during high winds and storm surges. In , two deaths occurred in state from tree falls—one in Keonjhar district's Panchapalli village and another in —prior to on May 26, 2021. In , seven deaths were recorded, including one from a falling in and at least two from amid tidal surges. Injuries totaled approximately 200, mainly from wind-related debris and structural collapses in coastal zones. The storm displaced hundreds of thousands, with over 1.2 million people evacuated from low-lying areas in India's and states, and an additional 1.3 million affected in Bangladesh's 16 coastal districts, many seeking shelter in camps. Vulnerable groups, including fishermen at sea and rural poor in exposed villages, faced heightened risks, exacerbated by the concurrent , which strained evacuation logistics and limited medical access in crowded shelters.

Economic and Infrastructural Damage

Cyclone Yaas inflicted substantial infrastructural damage across and , with official assessments indicating widespread impacts on housing, transportation networks, and utilities. In , approximately 284,000 homes were damaged, including over 100,000 fully destroyed structures predominantly composed of kutcha (mud-based) materials, while reported 18,094 houses affected, many partially damaged thatched or kutcha dwellings. Road infrastructure suffered extensively, with over 12,500 kilometers of roads damaged or blocked in and roughly 10,600 kilometers affected in , including 383 kilometers of department-maintained routes and extensive rural linkages. Embankments along coastal areas were breached or eroded, totaling 443 kilometers in and 332 kilometers in , exacerbating flooding in low-lying regions. Power grids experienced significant disruptions, with 4,188 high-tension and low-tension poles damaged in alongside 536 distribution transformers, and in , 10,689 poles and 1,975 transformers affected, cutting supply to millions across 14 districts in and key coastal areas in . Port operations at Paradip in were suspended from May 25, 2021, as a precautionary measure ahead of , halting cargo handling and vessel movements without reported permanent structural damage. Overall economic losses were estimated at INR 21,535 (approximately $2.9 billion) in and INR 610 (approximately $83 million) in , encompassing property, public assets, and preliminary relief costs. Agricultural sectors faced severe setbacks, with over 406,000 hectares inundated in —primarily fields—and 6,930 hectares affected in , resulting in crop losses valued at INR 3,424 (approximately US$460 million) in alone. These damages disproportionately impacted subsistence farming reliant on , with saline intrusion further compromising soil viability in coastal zones.

Environmental Consequences

Cyclone Yaas caused extensive damage to forests in the Indian and adjacent coastal areas, including uprooting of trees, reduced vegetation vigor, and heightened vulnerability due to storm surges, high winds, and associated salinity increases. Post-event analyses in regions like revealed significant tree fall and shifts in mangrove community structure, with cyclones like Yaas contributing to broader patterns of coastal changes and shoreline . Saltwater intrusion from the cyclone's penetrated inland, elevating across coastal lowlands and affecting zonation as well as adjacent freshwater-dependent habitats. This ingress disrupted local ecosystems, spoiling fish ponds and paddies integral to the delta's ecological productivity, while compounding in vulnerable embankment areas. Empirical surveys noted these changes persisting in soil parameters, though exhibited varying based on pre-existing density and surge exposure. The cyclone temporarily disrupted , inundating and displacing such as birds and marine species through flooding and altered gradients. Vegetation indices derived from data post-Yaas indicated acute stress in affected areas, but assessments highlighted limited permanent loss, with potential for regrowth supported by nutrient influx from freshwater inputs during the event. Heavy rainfall also promoted in rivers, depositing sediments that could influence long-term and accretion dynamics.

Aftermath and Recovery

Immediate Relief Efforts

Following landfall on May 26, 2021, the deployed 113 teams across five states for immediate search, rescue, and relief operations in flooded and damaged areas. The mobilized 17 flood relief columns in , along with additional engineer task forces, to clear debris, restore access, and support civil authorities in urgent restoration tasks. The assisted by distributing cooked food to affected populations in coastal regions like , . Over 14,000 relief camps were opened, sheltering approximately 230,000 people including 90,000 children, where essential food packets, , and basic medical supplies were provided under state and central coordination. In alone, around 500,000 individuals received shelter and initial aid amid widespread inundation. On May 28, 2021, the central government announced ₹1,000 crore in immediate financial assistance for affected states: ₹500 crore directly to Odisha for urgent relief, with the balance allocated to West Bengal and Jharkhand to facilitate aid distribution and infrastructure repairs. Relief operations adhered to protocols, including messaging on hygiene and distancing in camps, supported by organizations like to mitigate risks of secondary infections during the ongoing pandemic. These measures contributed to limited reported from post-disaster diseases, despite challenges from in shelters.

Long-Term Reconstruction

Following Cyclone Yaas, reconstruction efforts in and prioritized resilient housing under the (PMAY), which incorporates cyclone-resistant designs such as elevated plinths and reinforced structures for coastal areas. In , where over 20,000 houses were damaged, PMAY allocations supported rebuilding in affected districts like and , integrating multi-hazard features learned from prior cyclones. Embankment repairs focused on coastal barriers in West Bengal's and Odisha's region, where breaches exceeded 70 km in some areas. Initiatives included community-led "Food for Work" programs to restore earthen structures, supplemented by state proposals for sustainable strengthening using eco-friendly materials to prevent future saline ingress. The National Cyclone Risk Mitigation Project (NCRMP) facilitated upgrades to cyclone shelters and early warning infrastructure post-Yaas, expanding multi-purpose shelters in Odisha's coastal blocks and enhancing alert dissemination via apps like , which reached millions during the event. These measures, building on empirical reductions in casualties, supported near-zero deaths in subsequent cyclones through improved evacuation protocols. Economic recovery emphasized payouts and fisheries restoration, with disbursing Rs 6,800 per for rain-fed crops and Rs 13,500 for irrigated lands affected by inundation. pilots emerged for coastal agriculture, aiding rebound in and sectors, while NCRMP-backed resilient farming practices reduced overall crop losses by 40% in vulnerable zones.

Policy and Lessons Learned

The large-scale evacuation of approximately 1.5 million people from vulnerable coastal areas in Odisha and West Bengal prior to Cyclone Yaas's landfall on May 26, 2021, achieved a mortality rate below 0.002% among the exposed population, with total cyclone-related deaths in India numbering around 14 out of millions at risk. This empirical success, contrasted with historical events like the 1999 Odisha supercyclone that killed nearly 10,000, validated proactive strategies including multi-day advance warnings and cyclone shelters, informing policy expansions for nationwide scalability through enhanced community-based drills and infrastructure investments. Cyclone Yaas highlighted the need for multi-hazard planning amid the concurrent , prompting protocols that mandated shelter sanitization, mask and sanitizer distribution, and separate accommodations for infected individuals during evacuations. These adaptations minimized secondary health risks, with over 1,200 shelters prepared under health norms, and have since been embedded in India's National Disaster Management Authority guidelines to address overlapping crises like pandemics and natural disasters. Yaas's from a deep depression to a very severe cyclonic storm within 36 hours exposed limitations in real-time intensity forecasting, leading the to refine models with higher-resolution for better guidance. Subsequent validations in cyclones like Tauktae (May 2021) demonstrated improved track and intensity accuracy, reducing forecast errors by incorporating ensemble methods and satellite-derived inputs.

Controversies and Debates

Government Response Criticisms

Over 1.1 million people were evacuated from vulnerable coastal areas in and ahead of Cyclone Yaas's landfall on May 26, 2021, a measure credited by government officials with restricting the death toll to approximately 20 across and , far below projections for an unmitigated super cyclonic storm of its category. This evacuation scale and outcome echoed the effective protocols during in 2019, where similar preemptive relocations of over 1 million limited fatalities to 64 in densely populated regions despite comparable wind speeds exceeding 200 km/h. Critics, including opposition figures in , alleged delays in aid disbursement amid partisan frictions between the BJP-led administration and the TMC , with publicly seeking a Rs 20,000 crore relief package during a May 28, 2021, post-storm review chaired by , citing extensive infrastructural damages. Subsequent audits revealed that nearly 50% of compensation claims submitted to authorities were invalidated as fraudulent by early July 2021, prompting concerns over opaque verification mechanisms that may have hindered timely payouts to legitimate claimants, especially in flood-ravaged districts like Purba Medinipur and . Assessments of social inclusion highlighted disparities in response efficacy for marginalized castes and tribes, with 56% of surveyed respondents in affected and areas not relocating to designated shelters despite government warnings disseminated via television and local alerts, attributing this partly to logistical barriers, , and in institutional . The overlapping crisis further strained operations, as Yaas disrupted vaccination centers and heightened transmission risks in overcrowded relief sites, though empirical data indicated that pre-storm deployments of teams and advance releases from State Disaster Response Funds mitigated broader systemic failures.

Attribution to Climate Change

Some analyses have suggested that the intensification of Yaas was facilitated by elevated sea surface temperatures (SSTs) in the , which reached 30–31°C in the region during May 2021, exceeding the typical of 26.5°C required for formation. One study attributes this warming trend to influences, noting an increase in the area of the Bay with SSTs above 31°C from 0.1% in earlier periods to 29% by 2021, potentially contributing to observed in Yaas and similar pre-monsoon events. models in broader North assessments have projected 10–20% increases in rainfall associated with tropical cyclones under warming scenarios, with Yaas's heavy precipitation cited as consistent with such projections. However, no formal event-level attribution studies have been conducted specifically for Cyclone Yaas, limiting definitive causal links to anthropogenic . Empirical records indicate that the has historically produced intense cyclones with comparable or greater strength, such as the 1999 Odisha Super Cyclone, which attained a central pressure of approximately 912 hPa—far lower than Yaas's minimum of 970 hPa—demonstrating that rapid intensification and severe impacts predate recent warming trends. Spatiotemporal analyses of cyclone tracks from 1877 to 2020 reveal persistent high variability in intensity over the region, with natural factors like the El Niño-Southern Oscillation (ENSO) playing a dominant role; 2021 conditions transitioned from La Niña to neutral, which can enhance cyclone activity in the western North Pacific and basins without requiring anthropogenic forcing. Post-event evaluations, when adjusted for observational biases and improved detection, show limited evidence that Yaas represented unprecedented extremes relative to historical baselines, underscoring the influence of multidecadal natural variability over model-derived attributions. SSTs have long remained above 28°C year-round, supporting frequent genesis independent of recent global temperature rises.
