On Monday night, Chennai experienced widespread rainfall in several areas of the city, including Chennai Central, Egmore, Purasaiwakkam, Nungambakkam, and more. This sudden downpour was caused by wind discontinuity over the sea, according to a report from the Regional Meteorological Center (RMC).
The rainfall has led to a slight drop in temperature, providing some relief from the scorching heat that Chennai has been experiencing. On Monday, many areas in the city saw mild spells of rain, including Tondiarpet, Thiruvottriyur, Saidapet, Guindy, Egmore, Arumbakkam, Chromepet, Broadway, Mylapore, and Triplicane.
The RMC had earlier predicted moderate rain accompanied by thunderstorm activity for several districts of Tamil Nadu, including Chennai, over the next two days. A senior RMC official stated, "A trough/wind discontinuity runs from west Vidarbha to South Interior Karnataka across Marathwada and North Interior Karnataka and extends up to 1.5 km above mean sea level. Heavy rain is likely to occur at isolated places over the Nilgiris, Coimbatore, Tiruppur, Dindigul, Theni, Karur, Tiruchy Perambalur, Namakkal, Salem, Dharmapuri, Tirupattur, Tiruvannamalai, and Vellore districts for the next two days."
