The India Meteorological Department (IMD) has warned of extremely heavy rainfalls (more than 200 mm/day) in Tripura, heavy to very heavy falls in Nagaland, Manipur, Mizoram, south Assam and Meghalaya following depression over northwest Bay of Bengal off West Bengal – Bangladesh coasts.
“It is very likely to move north-northeast wards and cross West Bengal & adjoining Bangladesh coasts between Sagar Islands (West Bengal) & Khepupara (Bangladesh) over Sundarbans today,” the IMD said.
Localized Flooding of roads, water logging in low lying areas and closure of underpasses mainly in urban areas of the above region.
The IMD warned of the possibility of landslides in hilly areas of Northeastern states.
“Occasional reduction in visibility due to heavy rainfall, disruption of traffic in cities, minor damage to kutcha roads, possibilities of damage to vulnerable structure and damage to horticulture and standing crops in some areas due to inundation and squally winds may happen,” it said.
The IMD said that sea conditions will be rough to very rough. Fishermen are also advised not to venture into North Bay of Bengal and along and off West Bengal-Bangladesh coasts.
It further said that the depression over northwest Bay of Bengal off Odisha coast moved north-northeast wards with a speed of 24 kmph during past 6 hours and lay centred at 0830 hrs on Friday near latitude 21.3°N and longitude 88.4°E over Northwest Bay of Bengal off West Bengal – Bangladesh coasts, about 50 km southeast of Sagar Islands (West Bengal) and 200 km west-southwest of Khepupara (Bangladesh).
