28 June 2022, New Delhi: The monsoon has advanced into most parts of Gujarat with the northern limit passing through Deesa, Ratlam, Shivpuri, Rewa and Churk on Monday signalling a minor progress on the West Coast after breaking out of days-long logjam over Porbandar in Gujarat. The wait has cost it badly with rainfall deficit worsening rapidly into double-digits (10 per cent) on Monday from nil during the weekend. 

This was the second time that the monsoon was caught in a lock-up over the West Coast after Karwar in Karnataka shortly after onset. The rain deficit had peaked to 43 per cent then, until some record rainfall over East and North-East India made good the loss after June 15. The minor relief from the second deadlock over Porbandar came about even as India Meteorological Department (IMD) predicted a fresh spell of enhanced rain for central India from Monday and north-west India from Tuesday. 

Conditions are now favourable for its further advance into remaining parts of Gujarat, Madhya Pradesh and Bihar; some more parts of Uttar Pradesh; some parts of Rajasthan, Uttarakhand, Himachal Pradesh and Jammu & Kashmir during next 3-4 days. 

Low-pressure area 

The minor progress on the West Coast on Monday was overseen by a low-pressure area, first of the season, hovering on over the North-East Arabian Sea off the North Konkan-Sough Gujarat coasts, not far away from Mumbai. It has also thrown open the offshore trough in full length from South Gujarat to North Kerala. 

The IMD has now forecast isolated heavy to very heavy rainfall over Konkan and Goa during the next five days. Isolated heavy rainfall is forecast over East Gujarat, Madhya Maharashtra, Coastal Karnataka, Kerala and Mahe during this period; over southern parts of Saurashtra on Wednesday and Thursday; coastal Andhra Pradesh and Telangana on Wednesday; north interior Karnataka on Wednesday and Thursday; and south interior Karnataka from Tuesday from Tuesday to Thursday. Isolated heavy rainfall is likely over coastal Karnataka on Wednesday and Thursday.
