It was 2nd straight day of Chennai rains yesterday as many areas of the city came under intense gusts of wind and spells of heavy rains. Particularly around South Chennai & the southern suburbs the gusts of wind were very heavy with Thaiyur, near Kelambakkam recording 45 km/hour gust for a brief moment. This was reflecting in the rainfall numbers as well with the AWS at Thaiyur recording 17.4 mm the highest in the region.
While comparing to the previous day the overall rainfall pattern is on the lower side but the impact of thunderstorms was felt in terms of the gusts of winds across the city resulting in power cuts / trips at various places. While the Northern suburbs got good rains on Wednesday they missed out yesterday with mostly only passing showers happening in the area. Nevertheless it was a day of fairly widespread Chennai Rains.
After a brief break of about 5 / 6 days from the start of July rains have once again picked up in Tamil Nadu with North Tamil Nadu getting isolated thunderstorms at many places. There is a fair chance of thunderstorms today as well in the districts of Tiruvannamalai, Kanchiipuram, Villupuram, Cuddalore & adjoining Pondicherry. While the chance of Chennai Rains does exist it looks like the places South of the city has better chances of thunderstorms though the rain prospects will depend on the actual movement of the storms.
On a macro scale the Well Marked Low Pressure will continue to give isolated heavy rains in Central India around MP / Vidharbha region as it makes a slow movement towards the West. In the meanwhile thanks to the off shore trough parts of North Kerala particularly around Wayanad / Kannur / Kasargod and adjoining parts of Nilgiris could see isolated heavy rains in one or two places along with a few places in South Karnataka around the Madikeri region.
