Weather Conditions Triggering Rainfall

Yesterday’s Low Pressure area over the central parts of the north Bay of Bengal persisted as a well-marked low pressure area at 1730 hrs IST on July 24 (Thursday), 2025. It moved slowly west-northwestwards and intensified into a Depression by 0530 hrs IST on July 25 (Friday), centred over Northwest Bay of Bengal and adjoining coastal West Bengal and Bangladesh.

The system continued west-northwestwards at 13 kmph, crossed West Bengal and adjoining Bangladesh coasts between 0730 and 0830 hrs IST, and by 0830 hrs IST lay centred over coastal West Bengal and adjoining areas of Northwest Bay of Bengal and Bangladesh. It is very likely to move further west-northwestwards across Gangetic West Bengal, adjoining North Odisha and Jharkhand during the next 24 hours.

Meanwhile, the off-shore trough at sea level along Maharashtra-Kerala coasts persisted. Strong Westerlies and North Westerlies are likely to prevail over Kerala and Lakshadweep at lower tropospheric levels.
