A cyclonic circulation currently lies over Southeast Arabian Sea off Kerala coast in lower and middle tropospheric levels, informed India Meteorological Department (IMD) on Monday.
The system is likely to move west-northwestwards towards Southeast and adjoining East-central Arabian Sea. Under its influence, a low pressure area is likely to form over Eastcentral Arabian Sea around November 8, IMD said.
A trough runs from Southeast Arabian Sea and adjoining Lakshadweep area to Westcentral Bay of Bengal and adjoining south Andhra Pradesh coast in lower tropospheric levels.
Under the influence of both the systems, light/moderate fairly widespread to widespread rainfall is very likely over south Peninsular India during next 4-5 days and decrease thereafter, predicted IMD.
As per IMD, isolated heavy rainfall very likely over Coastal Andhra Pradesh, Lakshadweep today; Rayalaseema and Coastal Karnataka on November 6 and 7; over Kerala-Mahe during 6th-9th; over Tamil Nadu, Puducherry, Karaikal and South Interior Karnataka during 6th-8th November.
Heavy to very heavy rainfall has been recorded at isolated places over Tamil Nadu and Coastal Andhra Pradesh and heavy rainfall at isolated places over Coastal Karnataka and Kerala in the past 24 hours, informed IMD.
