The last couple of days have seen heat wave conditions over large swathes of Peninsular India as many places recorded not only the hottest day of the year but also broke some long standing records as well. On 30th March Chennai AP recorded 41.3ºC which was the highest recorded temperature ever at the Airport IMD observatory during the month of March. On the same day Trichy AP as well recorded the highest recorded temperature during the month of March for many many years. Meanwhile on 31st March Dharmapuri recorded 41.1ºC which was the highest recorded temperature in the city during both March & April Months. Karaikal recorded 37.5ºC on 31st March, while the highest recorded temperature during the month of March was 37.2ºC on 28th March 2001, this will be part of April month data as per IMD records.
The Well Marked Low Pressure area over Bay of Bengal has intensified into a Depression today morning and though showing a very disorganized structure it may intensify into a deep depression & continue on a NNE track towards the Myanmar coast in the coming 24 to 48 hours. Possible land interaction later could mean this disturbance may not become the first named cyclone of the year 2021 over the North Indian Ocean Basin.
On the temperature front over Peninsular India it appears today could be the peak for the current spell of heat wave conditions over Peninsular India with temperatures gradually reducing from tomorrow. While there will be no immediate reduction of temperatures to normal levels with weather models indicating most parts of Tamil Nadu to continue to see 2 to 4ºC above normal temperatures until mid of next week the good news is the heatwave conditions will start fading from tomorrow.
