Posted Tuesday Night:
BB-1 is now a Depression, at 6.5N and 75E....This could be well the first Depression in the Arabian Sea in March in many many years...See Vagaries blog of 21/22 March 2008 for similar conditions.
BB-1 likely to move N/NW.
Rains Likely in Coastal Karnataka, Goa by Thursday and in Pune by Friday.

Posted Monday Night:
1. Favourable MJO conditions in the Bay regions and a trough from the UAC towards the Bay Islands, prompted and hastened the formation of BB-1 at this time of the year. An Anti Cyclone in the Bay coincided with the Southerly location.
2, The anti Cyclone in the Arabian Sea, if it moves West, can make the BB-1 system track along/off the West Coast of India, off the coast till around 15N. This track is now a 25% probability.
3. Latest Location: Estimated at approximately 4.2N and 78.6E.

Konkan/Mumbai/Coastal Karnatak/Goa: Cloudy from Wednesday with light rains Thursday/Friday.

Posted Sunday 11th March  Night:

Very gusty winds and rough seas are predicted from Tuesday night over the Islands and off the Kerala Coast.Heavy rains also likely along Kerala coast and Lakshdweep Islands on 14th/15th March.
