Heavy Rain Likely over South-Tamilnadu and SriLanka-
The system INVEST-91B which intensified to a near depression status and has made landfall over Srilankan Landmass. The cloud bands associated with system are very strong and will pound the coast of Srilankan coast with heavy rainfall. The system as per the latest forecast trend, likely to move to Gulf Of Mannar and stay for some time there. Lets investigate the conditions in Gulf of Mannar and make some conclusions.
Map-1-LOCATION OF LOW PRESSURE:
MAP-2- CONVECTION AROUND THE LOW PRESSURE:
Conditions in Gulf Of Mannar--
Total Precipitable Water-71.821 kg/m^2
Total Cloud water-3.0887 kg/m^2
Sea-Surface Temperature-32 degrees
Heat potential-140 KJ/m^2
INFERENCE-
As the system reaches the Gulf of Mannar, it will reach to its peak threshold of convection and make a strong cloud band around its center. The places of South Tamilnadu will get a very heavy rainfall. Heavy rainfall will be confined on 16th May and by 17th May, the activity will be shifted to Central and North Tamilnadu.
NOTABLE EVENTS-
The system will move North-West and reach Gulf of Mannar by today evening. It will start tracking Northwards for some time and thereafter North-Northeast wards. I am expecting 16-20 May will bring out good rainy days to Tamilnadu.
WOS-ADVISORY:
- People of South-coastal Tamilnadu and Srilanka are requested to take precautionary measures to avoid the problems caused by floods.
- Heavy to very Heavy rain likely over many places of Srilanka and South Tamilnadu under the influence of Low pressure on 16th and 17th. By evening, the heavy rainfall might start.
