An off shore trough has formed along the East Coast of India. An embedded UAC is likely off the North A.P./Odisha Coast by the 17th. We shall observe the perseverance and strength of the trough next 1 or 2 days before tracking the UAC.
As the Monsoon advances into Northern regions of Bengal anfd Sikkim, the East winds there and the SW winds in South Bengal form a weak Line of wind Discontinuity. This is causing violent thunder storms in the Jharkhand and South Bengal regions, including Kolkata.

Wow ! South West Monsoon is giving a real treat to Goa...
Total Seasonal rains this Monsoon in various Goa stations till 13th Morning.
Panji with another 98 mms on 13th in the day till 5.30 pm IST, now totals 400 mms.
Vagarian Abhijit Modak from Badlapur pointed out the increasing and good rains in Ratnagiri (South Konkan) also, and it continues even on 13th. Ratnagiri has totalled 226 mms as on 13th morning , and add another heavy 101 mms on Monday in the day (till 5.30 pm IST), adding the Season's total to 327 mms.
As the rains in Ratnagiri and other South Konkan stations continue till date, Harnai totalling 212 mms. We cannot ignore such heavy rains and good totals...
I checked up on the Off Shore Trough scene and a slightly weak upper wind penetrating into South Konkan.
Due to the "spurt" in the feeble trough in the Goa/ South Konkan small regional area, there was a spurt of rainfall, enough to push the Monsoon current a short distance North.
With these, vagaries advances the South West Monsoon into South Konkan upto Harnai.
This will not change or affect the situation explained in yesterday, Sunday, post. The advance now remains halted as explained, and all dates mentioned in Sunday 12th post for Monsoon remain same.
The seasonal Low trough remains around 996 mb, and the "High" anti cyclone is forming in the 700 hpa level. So, another 4 days wait for the Peninsula advance is expected.
SWM is advancing into the NE States and Sikkim within next 2 days.
SE Sindh will be very windy with winds exceeding 40 knts. Gujarat will also experience strong W/SW winds next 3 days.
Mumbai: Day warming up. Next 3 days will be partly cloudy with passing showers in parts of City, daily rainfall not exceeding 7-10 mms. Monsoon cannot set in before 17th June.
Cloudy weather for North Konkan (Pen, Roha, Panvel), with passing showers for the next 3/4 days.
Pune will be partly cloudy with light rains in some parts. Proper Monsoon not reaching before 18th June.
Surat: Nothing except hot sultry weather for Surat thru the week. A stray shower from passing clouds. Strong winds from SW direction expected next 3 days.
