BB-5, as a Depression, has crossed the coast at 21.8N and 87.1 E near the Odisha/West Bengal border. As can be seen from the Satellite image , super-imposed on IMD image, the maximum effect of rainfall and clouds are seen in the Western quadrant of the system. Core estimated pressure is 993 mb. Outer periphery winds are around 40 kmph.
System will track NW and weaken, initially at the surface level and remain as a UAC for another 2 days.
As the system tracks NW, along the Monsoon axis corridor, the rains will move across Chattisgarh and Bihar (much needed) and U.P., and gradually weaken in Odisha. Tuesday onwards the NW plains including Delhi and Haryana will get heavy rains.
Vidharbha region may get good rains on Sunday 22nd.
An Upper air axis will hence form from North Gujarat to U.P. Inter action with another embedded UAC will bring good rainfall to Rajasthan, North India plains in 2 days from Saturday (next week).
For Pakistan most of the rainfall, the major part, from BB-5 is seen in the North and Upper Central regions from Monday. No major meaningful rains in Sindh.
Break Monsoon conditions may prevail after 26th as BB-5 moves into the Himalayan foothills. Meaning, widespread rains in Uttarkhand, U.P. and NE States. Break Monsoon conditions will reduce rains in the Central Indian region, and Peninsula.
