The southwest monsoon, which hit the coast of Kerala two days behind its regular schedule on Thursday, is most likely to reach Goa and Maharashtra early next week, according to the India Meteorological Department (IMD).
What will happen in the next 48 hours?
During the next 48 hours, the southwest monsoon is very likely to advance further into some more parts of the Central Arabian Sea, some parts of Maharashtra and Goa, remaining parts of Karnataka, some more parts of Andhra Pradesh, some parts of Telangana, remaining parts of Tamil Nadu, some more parts of central Bay of Bengal, some parts of northeast Bay of Bengal and northeast India.
Rainfall very likely over northeastern states in next 5 days
As per the IMD, due to the strengthening of lower-level southwesterly winds, widespread rainfall activity is very likely over northeastern states during the next five days. Isolated heavy rainfall is very likely over Arunachal Pradesh on June 4-5; over Assam and Meghalaya from June 4-8; and over Nagaland, Manipur, Mizoram and Tripura between June 5-7.
Widespread rainfall in Kerala, Tamil Nadu, Karnataka in next 24 hours
The IMD said that under the influence of the off-shore trough at mean sea level from south Maharashtra to south Kerala coast, and strengthening of westerly winds in lower tropospheric levels, widespread rainfall accompanied with thunderstorms, lightning and gusty winds with isolated heavy falls is very likely over Kerala, Tamil Nadu and Karnataka during the next 24 hours.
Currently, the Northern Limit of Monsoon (NLM) is passing through lat.14°N/ Long. 60°E, lat. 14.5°N/ Long. 70°E, Karwar, Harapanahalli (Vijayanagaram district), Anantapur, Arogyavaram, Vellore, Nagapattinam, lat. 12°N/ Long. 83°E, 15°N/89°E and 18.5°N/94°E.
Cyclonic circulation lies over southwest Uttar Pradesh
A western disturbance as a cyclonic circulation lies over Jammu and its neighbourhood between 3.1 km and 5.8 km above mean sea level. A cyclonic circulation lies over southwest Uttar Pradesh and nearby areas. Under the influence of these systems, isolated to scattered rainfall accompanied with thunderstorms, lightning and gusty winds is very likely over parts of the western Himalayan region and adjoining plains of northwest India during the next 24 hours.
