As the West Coast Off shore trough persisit ( Quote:IMD), S.Konkan/Goa are Continuously lashed by rains. Goa too has achieved the 1000 mms mark for this Monsoon.
After Malvan in S.Konkan, it is Patgaon (1048 mms)  in Maharashtra and Pernem (1156 mms) and Quepem (1034 mms) in Goa.Gaganbavda (Kolhapur) is at 890mms, while Amboli was 812 mms ( till 25th June).
The strength of the trough is really showing its might in the region with heavy rains persisting. 5-11 cms in the last 24 hrs have added to the totals. Rains remain weak in North Konkan.
The reasons for the divided rains are clear from this IMD chart, showing a weak trough off N.Konkan.

Mumbai had 1.6 mms at Colaba and no rai at S'cruz or at Vagaries. The off shore trough will remain in position till at least Saturday. A further weakening of the monsoon trough can possibly strengthen the trough off n.Konkan . It is resisted by lack of energy and momentum (weak MJO aided). Mumbai can still hold out hopes for some improved rainfall for Thursday.

Meanwhile, much needed rains are lashing Chennai now, Wednesday evening/night.Rainfall measured upto 7 mms till night.
The rainfall from cross Kerala has crept in thru western TN.
