In meteorology, a cyclone  is a large air mass that rotates around a strong center of low atmospheric pressure. Cyclones are caused by atmospheric disturbances around a low-pressure area distinguished by swift and often destructive air circulation. Cyclones are usually accompanied by violent storms and bad weather. The air circulates inward in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere.   They are known as typhoons in the China Sea and Pacific Ocean; hurricanes in the West Indian islands in the Caribbean Sea and Atlantic Ocean; tornados in the Guinea lands of West Africa and southern USA.; willy-willies in north-western Australia and tropical cyclones in the Indian Ocean.

 


Only when the wind speed touches 61 kmph (to 88 kmph) it is classified as ‘Cyclonic Storm’.   Please note that Standard Fire Policy names the peril covered as Storm, Tempest, Flood & Inundation (STFI) 

A day or so back, someone wrote - this cyclone is going to give very very heavy rains to KTCC (Chennai) to Pondy belts. Extreme caution and watch need to be there tomorrow (saturday) and chances of rains extending to Sunday also exists.  

It did rain but not anywhere near what was forecast.  According to The Hindu, Cyclone Fengal, which crossed the coast near Puducherry on Saturday (November 30, 2024) night, triggered heavy rainfall and strong winds over coastal districts in north Tamil Nadu, flooding low-lying areas and disrupting flights and EMU train services in Chennai. This is the second cyclone to develop over the Bay of Bengal this season. The Regional Meteorological Centre (RMC) at Chennai said that the cyclone’s advance spiral bands had crossed the coast by 7 p.m. with landfall expected to take three or four hours, with wind speeds gusting up to 90 km per hour. Heavy rainfall is expected to continue through Sunday (December 1, 2024), though rain intensity depends on cloud cover. The rain left areas in central Chennai, including Korattur, Koyambedu, Virugambakkam, Nungambakkam, T. Nagar and Alwarpet, inundated.  

Chennai airport was shut down and 226 flights were cancelled due to adverse weather conditions. Another 20 flights due to arrive in Chennai were diverted to other airports, including as far away as Guwahati. The Airports Authority of India said the airport would remain closed till 4 a.m. on Sunday (December 1, 2024).


 

According to IMD – the Cyclonic Storm “FENGAL” [pronounced as FEINJAL] over north coastal Tamilnadu & Puducherry remained practically stationary during past 1 hour and lay centered at 0030 hrs IST of today, the 01st December 2024 over the same region near latitude 12.0°N and longitude 79.8°E, close to Puducherry, as a cyclonic storm with a wind speed of 65-75 kmph gusting to 85 kmph. The cyclonic storm “FENGAL” will move west-southwestwards slowly and weaken gradually into a deep depression during the next 3 hours. The system is being continuously monitored by the Doppler Weather Radar at Chennai & Karaikal. 

The report added ‘observed rainfall from 0830 HRS IST of 30th Nov to  0030 HRS IST of 1st Dec  (0300-1800 UTC): -  Chennai (Meenambakkam): 11.4cm Chennai (Nungambakkam): 11.4cm
