Low pressure area to usher in rains over Coastal TN

After a brief let up for few days, rainfall activity has picked up drastically in north coastal TamilNadu and adjoining areas in past 24 hours and this is attributed to the prevailing low pressure areas in South West Bay of Bengal and neighbourhood. The scale and intensity of rains will increase in the coming days as the low pressure area dangles along Bay waters adjoining TN. Heaviest of the rains would be confined to coastal areas, more so in Cuddalore, Karaikal, Nagapattinam belt. Intensity of rains will be relatively lesser in adjoining places.

Dynamic models are of view that the prevailing low pressure area would move further north under the purview of western disturbance creeping into North West India around 13th November. In this scenario, rains will ease across TN by next week mid. Prevailing foggy conditions in North India is expected to improve on the back of northerly, north westerly surface winds taking over in next 48 hours.
