Fresh ‘low’ seen over Bay in next 3-4 days

The India Meteorological Department (IMD) has further extended the timeline for intensification of the low-pressure area over East-Central Arabian Sea on Friday when it saw fresh activity breaking out over the Bay of Bengal.

The prevailing ‘low’ may concentrate first into being ‘well-marked’ and further into a depression over the next three days subsequent to which focus will shift to the Bay where a fresh ‘low’ is forecast to develop.

New ‘low’ by Tuesday

The IMD expects the new ‘low’ to take shape by November 9 (Tuesday) next and get a move initially to the West and later to the North-West to approach the Tamil Nadu coast during the subsequent three days.

The short-to-medium outlook of the IMD suggests that the ‘ow’ may intensify at least a round, cross the Tamil Nadu coast, enter Interior Tamil Nadu and Kerala to subsequently emerge into the Arabian Sea.

Fresh bout of rainfall

It will likely another round of heavy to very rainfall over these States, but before this can happen, a cyclonic circulation has parked itself off the Andhra Pradesh coast on Friday from a trough previously lying over there.

Also present is an existing trough in easterlies that now runs from the ‘low’ over East-Central and adjoining Southeast Arabian Sea to North-East Arabian Sea off South Gujarat coast bringing rains to parts of the West Coast and parts of adjoining North Peninsula.

Rains for South

The IMD sees light to moderate rainfall occurring at many/most places with isolated thunderstorms and lightning over the South Peninsula and at isolated places over south Konkan, Goa, south Madhya Maharshtra and south Marathawada during the next five days.

Heavy rainfall may break out at over Tamil Nadu, Puducherry and Karaikal during this period; over Kerala and Mahe during next four days; over coastal Andhra Pradesh and Yanam during next three days; over south interior Karnataka, south Konkan and Goa during next two days.

The IMD expects the new ‘low’ to take shape by November 9 and get a move initially to the West and later to the Tamil Nadu coast during the subsequent three days.
