Now after a gap of two three days, pre-Monsoon weather activities will once again resume over many parts of Kerala and Tamil Nadu. These weather activities will occur in association with the formation of a cyclonic circulation over interior parts of Kerala and a trough extending up to Comorin area.
Therefore, we expect, on and off rain and thundershower activities are likely to occur in parts of Kerala and Tamil Nadu during the next three to four days. Even though intensity of these weather activities will not be very high but still few moderate spells are possible over many places of both these states.
However, Coastal Tamil Nadu and Puducherry including Chennai, Thanjavur, Karaikal, Cuddalore and Nagapattinam will remain almost dry with high day temperatures. But light thunderstorm activity may still affect few of these places.
Thus, we can say that, pre-Monsoon activities are going to pick up pace in southern parts of the country once again. Most affected areas will be interior parts of Tamil Nadu and Kerala. In fact, as rains will not be heavy, flood like situations will be ruled out and these rains will be beneficial for the crops.
Most water reservoirs of Tamil Nadu are in bad condition with less than 20% of water availability. Therefore, it is clear that the state is waiting for the onset of Monsoon eagerly, which takes places during the first week of June.
