West Coast Wakes Up as Southwest Monsoon set for revival

In a news which is likely to bring a lot of Cheer the west coast has started waking up from its mid season slumber as Southwest Monsoon is set for a revival under the influence of the Low Pressure area that has formed in the Bay of Bengal. While the revival is not likely to bring active monsoon conditions immediately the current spell of dry weather is likely to be broken. Since July 31st the Core Monsoon Zone Standardized Rainfall Chart is below average bringing the overall monsoon average to -5.1% as of yesterday.

Things have started to pick up on the West Coast already with some of the places starting to record meaningful rains.  Hulikal, Madikeri, Munnar, Anakayam have recorded moderate to heavy spells of rains yesterday with possibly things improving further from today as the Low Pressure moves inland making its journey across the Northern parts of Peninsular India.

Thanks to the formation of the Low Pressure in Bay the monsoon trough which has parked itself in the foothills of Himalayas for more than a fortnight will slowly get dragged south closer to the Low Pressure Area as it traverses across the land.  This movement of trough is a key ingredient in breathing life back into monsoon dynamics with possibly the subsequent Disturbance in a few days possibly making things pick up on the monsoon front.

Closer home yesterday saw parts of Chennai, in particular around the Northern suburbs of the city enjoyed heavy thunderstorms late in the evening while most other parts of the city also enjoyed moderate rains.  As was the case day before yesterday while the interior parts of Tamil Nadu around Salem, Tiruvannamalai, districts enjoyed some spells of rains the most intense action happened in the extreme parts of North TN around Chennai.

As mentioned in our yesterday’s post we could possibly see a temporary break for us in terms of active thunderstorms with West Coast waking up from its slumber.  While isolated thunderstorms may continue the increased wind speeds triggered by the low will no more allow thunderstorms to develop intensity and drop heavy rains in one place.
