Deep Depression Nears Andhra Pradesh, Bringing Heavy Rainfall Risk
A deep depression is a strong weather system over the Bay of Bengal.
It is expected to reach land near Kalingapatnam in Andhra Pradesh on Wednesday night.
The system is moving more slowly than it did earlier.
Because it is slow, it may bring very heavy and lasting rain.
Winds are expected to cause less damage than the rain.
The system may travel west after reaching land.
It is expected to affect parts of West Bengal on Thursday and Friday.
Later, it may move toward Chhattisgarh and gradually become weaker.
Kolkata and other parts of South Bengal may receive light to moderate rain from 26 September.
The deep depression over the Bay of Bengal is expected to make landfall near Kalingapatnam on Wednesday night.
The system had slowed to 5 kmph by Wednesday, compared with 18 kmph on Monday.
It is expected to move inland between Visakhapatnam and Gopalpur, then track mostly westward.
Forecasters expect heavier rainfall impacts than wind damage because the system is moving slowly.
Asansol recorded 50 mm of rain and Kolkata recorded 24 mm by Wednesday evening.

Quotes
Regional Meteorological Centre scientist
A weather scientist associated with the Regional Meteorological Centre.
“Today’s system is moving at a slow speed. Therefore, it is likely to take the whole daytime tomorrow to cross the region. The impact of the system would therefore be more from the rainfall than high winds because of incessant rains.”

“After entering land, the direction of the system is likely to change. In the Bay of Bengal, its tilt was mainly towards the north of the northwest. After hitting land, its track is expected to be largely westwards.”
