Isolated Heavy Rains in Kerala, Parts of TN & Karnataka Expected

With the advent of April Rains in Kerala seem to be an almost daily affair thanks to the development of the Line of Wind Discontinuity at lower levels regularly.  This Line of Wind Discontinuity creates the necessary instability in the atmosphere to provide rains for the West coast of Peninsular India particularly to Kerala and parts of extreme South Tamil Nadu.

Yesterday saw parts of Coimbatore district record fairly heavy rains in the evening.  The IMD observatory in Kangeyam has recorded 36 mm rains while the Tamil Nadu Agricultural University AWS at Sarcarsamakkulam a suburb of Coimbatore has recorded 52 mm rains from the same spell.  Other observatories in and around the district has recorded rains as well of varied intensities.

Today also there is a fair chance of rains over the Western side of the Peninsular India with parts of Kerala, South Interior Karnataka & Western Tamil Nadu in line to receive fairly heavy rains at one or two places.  Places along the high ranges in Kerala, Wayanad, Kottayam & Pathanamthitta along with parts of Trivandrum could see heavy rains in Kerala at isolated places.  Over in Tamil Nadu the Nilgiris district could see heavy rains in one or two places along with the adjoining parts of South Interior Karnataka. There is some chance of early showers for Coastal Tamil Nadu but this would be at best light showers in one or two places particularly to the south of Nagapattinam.

On the temperature front models show some bit of easing for the interior places though at most places temperatures are expected to stay in the high 30s with mostly around 38 degrees as the pattern.  Coastal TN could see the temperatures closer to normal at around 35 degrees which is a degree or so lesser than a few days back.
