The Low Pressure in Bay of Bengal has been showing signs of weakening as expected over the last day or so. Currently lying slightly to the Southwest of Andaman Islands it is expected to move in a Westward direction towards the coast of Sri Lanka.
As things stand the Low Pressure is now associated with an Upper Air Cyclonic Circulation upto 3.1 kms above mean sea level, this is down from the 5.8 kms above mean sea level on 11th February. This is a confirmation of the weakening trend the Low Pressure in Bay of Bengal is going through.
The satellite map comparison over the last 24 hours or so clearly indicates the loss in convection the disturbance is undergoing. It is quite clear the Low Pressure in Bay of Bengal is weakening drastically under unfavorable conditions. Along with this the development of the Southern Hemisphere disturbance at the same latitude a little further away from the equator meant pretty much less chance for the Low pressure in Bay of Bengal to develop into anything meaningful.
In the meanwhile maximum temperatures in South India is expected to be above normal with fairly hot conditions prevailing over most interior places of Peninsular India. Yesterday saw Anantapur in Rayalaseema region record a 100°F settling at a day time max of 38.3°C possibly the second highest temperature recorded this year in South India so far. Similarly Palakkad in Kerala recorded 37.2°C which is possibly the highest of this season so far.
The trends of high day time temperatures are set to continue along most places of South India as pretty much dry weather is expected to rule the roost over the region during the weekend. Most places in Tamil Nadu are expected to see temperatures in the region of 32 / 33°C while a few places could see temperatures closer to 35°C. There is a fair chance of Salem recording another day of 35°C after yesterday’s 35.2°C. Night time temperatures are expected to be moderate with partly cloudy conditions keeping the humidity on the higher side
