Report Dated 18th November, 2023

Time of Issue: 1000 UTC

Synoptic features (based on 0300 UTC analysis):

Yesterdays Cyclonic Storm Midhili (pronounced as Midhili) over
Northwest and adjoining northeast Bay of Bengal moved
north-northeastwards and crossed Bangladesh coast near Khepupara
during 1430-1530 hrs IST of 17th November and moved across the
Islands of Bangladesh as a cyclonic storm with maximum sustained
wind speed of 65-75 kmph gusting to 85 kmph and lay over coastal
Bangladesh at 1730 hours IST of 17th November. Thereafter, it moved
northeastwards and weakened gradually into a deep depression over
Tripura and adjoining Bangladesh in the same midnight (2330 hours
IST). Further moving northeastwards, it weakened into a depression
over Tripura and adjoining Bangladesh & Mizoram in the early morning
(0530 hours IST) and into a low pressure area over North Tripura and
neighbourhood in the forenoon (0830 hours IST) of today, the 18th
November.

It is likely to continue to move further northeastwards and become
less marked during next 06 hours.
