CITY, COASTAL DIS­TRICTS BRACE FOR HEAVY RAINS

Spells of in­tense show­ers likely for two days; low pres­sure to be big in size and not too con­cen­trated, mak­ing the clouds spread over a large area

Sunday Express - - CHENNAI - @ Chennai

THE In­dia Me­te­o­ro­log­i­cal Depart­ment (IMD) has is­sued a heavy rain­fall warn­ing to Chennai and other coastal dis­tricts in the State for the next two days. The rain­fall ac­tiv­ity would com­mence after mid­night on Satur­day.

The weather mod­els are in­di­cat­ing that the rain­fall would be very in­tense at times, enough to worry the peo­ple liv­ing in the flood-prone ar­eas.

S Balachan­dran, Di­rec­tor, Area Cy­clone Warn­ing Cen­tre, said the low pres­sure is per­fectly placed over south­west Bay of Ben­gal near Sri Lanka with as­so­ci­ated cy­clonic cir­cu­la­tion ex­tend­ing up to 5.8 km above mean sea level.

It is sim­i­lar to the low pres­sure that brought heavy rain in the first week of this month, but the only dif­fer­ence is that this sys­tem is very broad and the con­ver­gences will be em­bed­ded within it. This means rain is con­firmed. How­ever, the in­ten­sity of spells is dif­fi­cult to fore­cast.

“The in­ten­sity of the spells can only be pre­dicted on an hourly ba­sis. The now­cast­ing in the IMD web­site will put out an update on the in­ten­sity of the spell ev­ery two hours. We are track­ing the sys­tem very closely and the reg­u­lar com­mu­ni­ca­tion chan­nels with the ad­min­is­tra­tors is kept ac­tive to put timely in­for­ma­tion that would be help­ful for quick de­ci­sion-mak­ing,” he said, not rul­ing out the chances of re­ceiv­ing heavy to very heavy rain­fall.

Weather blog­ger Pradeep John said the low pres­sure is very big in size and not too con­cen­trated. So, the clouds are spread over a large area. The sys­tem will move north-north­west­wards and there is a west­ern dis­tur­bance as well.

Some spells are ex­pected to be heavy and very heavy, par­tic­u­larly the belt of Tiru­val­lur, Chennai and Kancheep­u­ram.

Mean­while, In­dia Me­te­o­ro­log­i­cal Depart­ment is fore­cast­ing an­other fresh low pres­sure to form over south­east Bay of Ben­gal and neigh­bour­hood on Novem­ber 14.
