The system formed on Saturday over North Andaman Sea and neighbourhood lay over North Andaman Sea and adjoining East-Central Bay of Bengal now.
It is likely to continue moving west-north-westwards and intensify into a depression over East-Central Bay of Bengal on September 21 and into a deep depression over West-Central Bay of Bengal on September 22.
Maintaining the same track, it is very likely to reach West-Central and adjoining Northwest Bay of Bengal near South Odisha-North Andhra Pradesh coasts around the morning of September 23.
Under its influence, squally weather is expected over the sea. Wind speed reaching 40-50 kmph gusting to 60 kmph is very likely over Andaman Sea and adjoining East-Central Bay of Bengal on September 20. It is likely to increase to 45-55 kmph gusting to 65 kmph over East-Central and adjoining Northeast Bay of Bengal on September 21, and 50-60 kmph gusting to 70 kmph over Central Bay of Bengal and 40-50 kmph gusting to 60 kmph over adjoining North and South Bay of Bengal on September 22.
According to the IMD, wind speed is likely to further increase to 55-65 kmph gusting to 75 kmph over West-Central and adjoining Northwest Bay of Bengal on September 23 and will prevail till the evening of September 24. Squally wind with speed reaching 55-65 kmph is likely along and off South Odisha-North Andhra Pradesh coasts on September 23 till September 24 evening, while squally wind with speed reaching 40-50 kmph gusting to 60 kmph is likely along and off West Bengal and South Andhra Pradesh coasts from September 23 to 24.
this apart, sea condition is very likely to be rough over Andaman Sea and adjoining East-Central Bay of Bengal on September 20, becoming rough to very rough over East-Central and adjoining Northeast Bay of Bengal on September 21, over Central Bay of Bengal on September 22, and over West-Central and adjoining Northwest Bay of Bengal and along and off North Andhra Pradesh-Odisha-West Bengal coasts till September 24.
Fishermen have been advised not to venture into Andaman Sea till September 21, East-Central and adjoining Northeast Bay of Bengal from September 20 till September 22, and West-Central and adjoining Northwest Bay of Bengal and along and off Andhra Pradesh-Odisha-West Bengal coasts from September 22 till September 24.
