The low pressure area over northeast Arabian Sea and adjoining Gujarat Region has become less marked, and the pressure measures 1008 mb.
The UAC previously over south Kerala and neighbourhood now has has merged with the above system.
With this, as we witness the Arabian Sea systems now fizzling out, a marked decrease in rains in Mah and Gujarat.
But, a marked increase in rains is on the anvil. In the east. A low is expected to form by tomorrow, off the T.N. coast, and, as a result, the state's coast shall receive copious rainfall from tomorrow. Chennai is also in for some heavy rains from Thursday evening.
The low will ride on an easterly pulse, and travel west, across T.N. and precipitate rains over Kerala as well on Friday.
