UPDATE at 6-00 PM, 17th May, 2016.
Mr Jason Nicholls, a Senior Meteorologist/International forecasting manager @ AccuWeather. has forecast that there will be heavy rains on Thursday, 19th May. His meteorological forecast coincides with our astrological prediction.
As per our astrological analysis, Moon comes in direct opposite sign to Venus on the midnight of 18th. This opposition means heavy rainfall as per ativrishti yoga (mentioned above in the article). This opposition continues till 19th midnight after which Venus crosses over to Taurus, the next sign. As per this, rainfall will start decreasing from 20th / 21st onwards and stop thereafter. Mr Jason's tweet is reproduced below.
Note on Floods:-
The astrological indicators do not indicate the floods such as the one witnessed in last December. There may be flooding of the streets but no calamitous rains to swell Adyar river and the 50+ lakes in Chennai including Chembarambakkam. The absence of Sun, Mars and Saturn in alternate signs is an indicator of this. The present rains is mainly attributable to Budha - Shukra sameepyam and some triggers by planetary crossing.
But the date (19th May) of heavy rainfall is the counting date. The EC must take this in to consideration.
UPDATE on 22-05-2016
The Depression went past off the Chennai coast and was moving to the east of Vishakapatnam by 20th May. Venus crossed to Taurus on that day. As written in the article above, on the day of entry into a sign by Venus, there will be copious rains.
Sudden thundershowers occurred in Hyderabad causing heavy damage to life and property.
The Depression by now called as Cyclone Roanu went along the East Indian coast and made a landfall in Bangladesh on 21st May.
