Eastern Parts of Rajasthan has also been receiving heavy rains with many areas seeing flash floods. Due to the interplay between these two Circulation places in North AP and Northern parts of Telangana could see heavy rains in a few locations.

The wind charts clearly indicate the weak monsoon conditions over Kerala and South Karnataka. An imaginary line running along 13N seems to be the border between the active and not so active monsoon regions.
