Gradually the rain belt seems to be shrinking and is now confined to South Coastal Andhra Pradesh.
In a span of 24 hours, from 8.30 am on Thursday, Visakhapatnam, Chennai and Tuni received traces of rain. Narsapur received good showers and recorded 14 mm of rain.
Rainfall is now confined to Coastal Andhra Pradesh, Tamil Nadu and Rayalaseema region. By tomorrow, the rain belt will narrow down further. The confluence zone will become insignificant after 24 hours.
A fresh weather system in association with a trough will start affecting weather in Peninsular India once again from January 24. The trough will come up across the Tamil Nadu coast off Southwest Bay of Bengal.
This trough along with the cyclonic circulation over the Arabian Sea will bring light to moderate rain over interiors of Tamil Nadu, South Interior Karnataka, South Coastal Andhra Pradesh and some parts of Kerala.
This could bring some relief from the hot and humid weather in some parts of the Peninsula including entire Kerala. This is the time when winter starts leaving Peninsular India. February marks the commencement of the summer season in this region.
