Overview

• IMD forecasts one or two spells of moderate to occasionally heavy rain with thunderstorms and lightning in Chennai on Saturday, with generally cloudy skies.
• Neighbouring districts including Kancheepuram, Tiruvallur and Chengalpattu are also in line for heavy rain, with isolated intense showers in several other Tamil Nadu districts.
• Wet conditions are expected through the first week of October with intermittent showers and thunderstorms as the region moves toward the northeast monsoon.
• Meteorologists say the southwest monsoon’s withdrawal over peninsular India is running late and may linger over Chennai until early to mid-October before the seasonal shift.
• Daytime temperatures should hover near 32–33°C with nights in the mid‑20s, and authorities have urged vigilance for waterlogging despite no severe statewide warnings.
