Rains in Tamil Nadu to see a break as Monsoon shifts focus to West Coast

After almost a week of Fairly regular and widespread rains in Tamil Nadu particularly around the interior regions it is time for the rains to take a break.  Yesterday saw many places in Chennai record light to moderate rains in the evening while southern suburbs enjoyed one or two heavy spells as well.  Taramani recorded 25 mm of rains for the 24 hours ending at 8:30 AM while places like Anna University, Nungambakkam & Meenambakkam recorded between 2 & 4 mm for the same period.

A look at the precipitation charts for the last 7 days or so will clearly indicate how much rains in Tamil Nadu has been much higher than the normal for this time of the year in specific to the interior regions.  The interior region of Southern Peninsular India has seen about 200% above average rainfall at many places while in a few places it has seen in excess of 400% of normal average.  Weather_Update_2

With an Upper Air Cyclonic Circulation over North Bay now aiding the monsoon trough move back into Central India we are likely to see an increased monsoon surge over West Coast & Central India.  This is likely to set forth the next active phase of Monsoon 2016 for the next few days, as the developing Low from Bay could move inland over the next couple of days or so and improve monsoon intensity.


With the West Coast set for an active phase we are likely to see the rains slow down in the East Coast of Peninsular India.  Rains in Tamil Nadu is likely to become scattered and more isolated today as we get set for a dry spell over the next week or so.  While today we could see some passing showers in a few days over North Tamil Nadu the chances of intense thunderstorms looks less likely and similarly widespread rains in Tamil Nadu are less likely as well.

Chennai could see cloudy conditions through the day with some light drizzle or passing showers at times.
