BB1, is likely to descend to seal level as a low pressure by tonite. Initially, at around 998 mb, it will form off the Orissa coast, with clouds in the southern and SW quadrant of the system.
Since a seasonal trough today runs from west to east, with its western end over Upper Sindh and running thru Rajasthan, U.P. and the eastern end into the system.
Normally, BB1 will track along this trough. Presuming the trough to remain in the same position, which it should, the low, on deepening into a well marked low by Thursday, will track into North M.P. and thence into U.P.
But, bearing in mind the clouding is in the south and SW of the centre of BB1, rainfall will be more in Eastern Vidharbha initially, and moving into east M.P. from Thursday/Friday. Similarly, the eastern end pf the trough will get active to precipitate heavy rains in the NE states, and presumably move SWM into more areas of the east and Nepal.
In line with BB1, west winds will be attracted towards the low on the west coast. Heavy rain along North Konkan accordingly from Thursday. Mumbai forecast put up yesterday remains intact !
As-1 is now out and over, done with. Precipitation is dying out off the Saurashtra coast. I understand there were traces of rain in Karachi yesterday. Dont think more can be expected from "ex-AS1"
Next update with forecast map tonite at 10.30 pm.
