The India Meteorological Department (IMD) on Wednesday issued a fresh alert for heavy rainfall at isolated locations in Tamil Nadu on December 3, attributing the forecast to the lingering impact of Cyclone Ditwah. The warning comes as several northern districts continued to receive rain on Tuesday, with the death toll from rain-related incidents rising to four.
Cyclone Ditwah Weakens, Flooding Reported in Low-Lying Areas
According to the IMD, heavy rains triggered flooding in low-lying regions and caused significant traffic disruptions across parts of Tamil Nadu. The deep depression, which had already weakened into a depression, is “very likely to become a well-marked low-pressure area,” the department said.
Chennai recorded an average of 15 cm rainfall in the 24 hours between December 1 and 2, and the city is expected to see moderate showers on Wednesday.
