Monday Night Post:

"Madi" is still a Severe Cyclone, with core winds at 60 knts and pressure 970 mb at T4.8...Located , having moved due North in last 12 hrs, at 15.3N and 84.7E. 
Will track NNE slowly and weaken.

A comparatively dry patch of air also runs along the Eastern coast, and is seen seeping into the southern half of the cyclone semi circle. However, the wrapping around the cyclone is slow. 
Since large patches of dry air are to the West, Madi is going to encounter dry air and weaken rapidly after 24 hrs. System most likely to dissipate in the West-Central Bay itself. ( Before hitting land as a system).

Very dry humidity conditions were observed along the West Coast of India, North of Goa. Maily due to strong NE winds blowing from the land into the sea. NE winds due to HPA in NW India.
Ratnagiri had an unusual low humidity of 8%, Mumbai low humidity was 16 % and inland Pune was very dry at 9% humidity !
This extremely dry patch runs from South Gujarat to Goa. Dry air (too a lesser extent) runs Southwards towards the Kerala coast, (Less humid as winds are Northerly here) and covering the Southern Seas around Sri Lanka.
