In the month of March, where most parts of North and East-northeast India are still under the influence of successive weather systems affecting the northern hills and plains, parts of South India start experiencing hot day conditions with very high maximums.
Since the last two to three days, parts of South India particularly Rayalaseema and Interior Tamil Nadu have been experiencing heatwave like condition, with maximum temperatures reaching up to 40 degrees.
Yesterday, Tirupati recorded its maximum temperature at 40.4˚C, followed by Tiruttani 40.1˚C, Nandyal 39.4˚C, Salem 39.3˚C, Kavali 39.2C, Madurai 39.2˚C, Anantapur 39.2˚C, Vellore 39.2˚C, Gulbarga 39.1˚C and Nellore 39.1˚C.
At present, a trough is extending from interior parts of Tamil Nadu to Comorin region. However, we do not expect any significant weather activities in association with this system, but chances of isolated patchy rain for short duration over few places cannot be ruled out.
Further also, in the coming days, in the wake of developing feeble weather systems in the form of trough or embedded cyclonic circulations, between March 8 and 10, isolated weather activities in the form of rain or thunderclouds may occur over interior parts of Tamil Nadu and parts of Kerala.
As these rains will not be very significant, the rising trend of temperatures will continue and heatwave like condition may even cover more parts of Tamil Nadu and Andhra Pradesh.
