Posted on: 10/Oct/2023 4:58:34 PM
The Regional Meteorological Centre (RMC) issued a forecast on Tuesday, indicating the likelihood of heavy rainfall and thunderstorm activity in 14 districts of Tamil Nadu. This weather phenomenon is attributed to a cyclonic circulation observed over the sea, which is expected to have a cooling effect on the maximum temperatures in both coastal and interior regions in the coming days.
Specifically, a cyclonic circulation has been identified over the Comorin area and its neighboring regions up to an altitude of 1.5 kilometers above mean sea level. Additionally, a trough extending from Rayalaseema to the Comorin area, across Tamil Nadu, also up to 1.5 kilometers above mean sea level, has become less pronounced. As a result of these atmospheric conditions, a yellow warning has been issued for 14 districts in Tamil Nadu. These districts include Coimbatore, Nilgiris, Erode, Krishnagiri, Salem, Dharmapuri, Virudhunagar, Sivaganga, Trichy, Namakkal, Karur, Dindigul, Madurai, Tiruppur, and Theni, with heavy rainfall expected over the next two days.
For the remainder of the state, light to moderate rainfall is anticipated in the coming days. This forecast comes as a relief to several areas that had experienced a surge in temperatures. Furthermore, the cyclonic circulation is expected to bring down the maximum temperature in coastal and interior districts. Additionally, Chennai, Tiruvallur, and Chengalpattu are expected to witness convective rainfall during nighttime hours.
In the past 24 hours, numerous areas in Tamil Nadu experienced moderate to heavy showers. Notably, Tirupur recorded the highest rainfall at 11 cm, followed closely by Ramanathapuram and Coimbatore, each receiving 9 cm of rainfall. Salem recorded 8 cm, while Madurai and Nilgiris each received 7 cm of rainfall.
It`s important to note that Tamil Nadu and Chennai had received excess rainfall during the southwest monsoon from June to September. However, the current situation presents a deficit, with the state experiencing a 46 percent rainfall deficit and Chennai recording a 65 percent deficit, having received only 19 mm of rainfall compared to the normal 56 mm from June 1st to October 10th.
