Cyclonic Storm Burevi is a currently active tropical cyclone which has made landfall in Sri Lanka and is threatening parts of southern India. The ninth depression and fifth named storm of the 2020 North Indian Ocean cyclone Season, Burevi originated from a low pressure area which formed on November 28. The system gradually became a depression on November 30, with the JTWC issuing a TCFA soon after. The depression then was upgraded into Cyclone Burevi the following day. Burevi slowly intensified reaching its peak intensity on December 2, just before making landfall in Sri Lanka. Burevi then weakened, entering the Gulf of Mannar the next day.

On November 28, a low pressure area formed off the coast of Aceh. It gradually intensified into a depression on November 30.[1] The JTWC then issued a Tropical Cyclone Formation Alert on the system, that same day.[2] At 3:00 UTC on December 1, the depression was upgraded into a deep depression.[3] At 15:00 UTC, both IMD and JTWC upgraded to cyclonic storm and tropical storm respectively and it was named Burevi, the fifth named storm of the season.[4][5] The name was initially suggested by the Maldives.[6] At this time, microwave imagery showed well-defined convective banding wrapping tightly around the low-level circulation (LLCC).[7] At 15:00 UTC on December 2, Burevi reached its peak intensity with 1-minute sustained winds of around 85 km/h (50 mph) and a barometric pressure of 996 mbar.[8] Shortly afterwards, Burevi made landfall along the east coast of Sri Lanka according to the Indian Department of Meteorology.[9]

After weakening over Sri Lanka, Burevi exited into the Gulf of Mannar, early on December 3.[10] However, Burevi slowed down quickly as it became stuck in a col between two subtropical ridges on December 4; thus it stalled just west of Sri Lanka while it weakened back down to the equivalent of a tropical depression due to increasing vertical wind shear.[11]

Preparations

A Cyclone Alert was put in place for South Tamil Nadu, South Kerala, and Sri Lanka upon formation.[12]

Sri Lanka

Burevi approaching Sri Lanka on December 1

In advance of Burevi, a red alert was imposed by the Sri Lanka Department of Meteorology.[13] Sri Lanka's meteorological department also warned of storm surge, flash flooding, and damage to homes and power lines.[14] A red alert was also issued. Fishing and naval activities were expected to be suspended in Sri Lanka starting December 2, according to the IMD.[15] The IMD also issued storm surge warnings for the East Coast of Sri Lanka.[16] More than 75,000 people were evacuated along the east coast of the country, with 237 relief centers opening in the district of Trincomalee. Schools were shut down in the Northern Province and Eastern Province until at least December 4 due to the storm.[17] The Director-General of the Disaster Management Centre said that 50 shelters were opened in each district of the North and East provinces.[18]

India

On December 2, the IMD issued an orange message for southern Tamil Nadu and southern Kerala.[19] This was then upgraded into a red message by December 3.[20] 26 NDRF teams were deployed in both Tamil Nadu and Kerala, ahead of the storm.[21]

Tamil Nadu

63 relief centers were opened in the Thoothukudi district where 30,000 sandbags were prepared to stop breaches in irrigation tanks.[22] The IMD issued a No. 3 Hazard warning for the Pamban port due to high winds on December 3.[23]

Kerala

On November 30, a red alert was issued for the districts of Thiruvananthapuram, Alappuzha, Kollam, and Pathanamthitta. While an orange alert was put in effect for Kottayam, Idukki, and Ernakulam.[24] Authorities in the area opened more than 2,000 relief camps, while banning fishing from December 3–6.[25] In the districts of Thiruvananthapuram, Alappuzha, Kollam, Pathanamthitta, and Idukki, a public holiday was declared for December 4. The Trivandrum International Airport was also forced to shut down for part of that day.[26]

Impact

Sri Lanka

At least two people died, six people were injured, 57 houses were fully destroyed and 2,753 houses were partially damaged by Cyclone Burevi, Sri Lanka's Disaster Management Centre stated.[27] The 2 fatalities were residents of Chankanai and Chavakachcheri areas of Jaffna district. More than 12,200 people from 3,500 families were impacted in total.[28] Four fishermen went missing during the storm, including 1 from Jaffna and three from Mannar. [29] 4 people were injured in the town of Valvettithurai.[30] Burevi produced heavy rainfall over Sri Lanka, peaking at 203.5 mm (8.012 in) in Alampil.[31] Roughly 10,336 people in the country were displaced by the storm.[32] However, Pradeeep Kodippili, the assistant director of Sri Lanka’a Disaster Management Centre stated that, “District disaster management units are reporting that no major damage has been caused by the cyclone.”[33] The city of Trincomalee was estimated to have been the hardest hit, and the many evacuated were sent to 237 individual evacuation centers.[34] According to European Civil Protection and Humanitarian Aid Operations, an additional person was missing and roughly 10,336 people were displaced by Burevi.[35]

Aftermath

Sri Lanka

As the storm moved over Sri Lanka, Vavuniya District Secretary, S.M. Saman Bandulasena, stated that arrangements and funds had been made to provide immediate relief following the storm.[36] UNICEF delivered 1,000 tarps, 10 family tents, 10 water pumps, and water purification tablets to the government of the country.[37]
