The Sub_Continent Expectations from Thursday 20th June till Sunday 23rd June:
1. An UAC forming around the Andaman Islands in the Bay will travel NW. Will, mostly, descend to sea level on Sunday 23rd, and BB-4 will be off the Orissa coast.
Another UAC forms off the TN coast, but merges in the trough (formed by the UAC) in the Bay.
2.The west coast trough will persist as a weak trough.The Northern end of the trough is supported by an Upper Air trough in the Sea. Some spill over showers in Saurashtra.
Possibly, a vortex may form for a couple of days off the Karnataka coast on the weekend.Heavy rains ( 40-100 mms) in Coastal Karnataka (weekend). Variable (10-40 mms) rainfall along rest of west coastline. Average/Below average rainfall in interior Mah.and Karnataka.
3. A weak low forms in the Arabian Sea off the Oman Coast on Thursday 19th. It imminently moves inland. Some light rains in Eastern Oman.
The resultant SW winds into SE Sindh may bring light rains to SE Sindh region and corresponding coast.
4.The Monsoon axis runs along the Himalayan foothills. Almost merging into Nepal on Friday.Heavy rains in Nepal.
The extended eastern arm remains weak. Maybe just extending to Meghalaya by Saturday.Heavy rains in Northern Bangladesh and Meghalaya.
Almost dry and no meaningful rains in NW India and most of Pakistan. SWM remains stationary.
