Chennai Weather to Worsen by Weekend; IMD Forecasts Widespread Rain Across Tamil Nadu

Chennai — Tamil Nadu is gearing up for a rainy and unstable weather pattern this week, with the India Meteorological Department (IMD) forecasting light to heavy rainfall across multiple districts, including worsening weather conditions in Chennai by the upcoming weekend.

The state, already under intermittent cloud cover and localized showers, is expected to witness intensified rainfall activity as moisture-laden winds strengthen over coastal and interior regions.

Rainfall Expected Across Key Districts

According to the IMD’s latest forecast, Tamil Nadu will likely experience a mix of moderate and heavy showers throughout the week. The rainfall distribution covers:

• North Tamil Nadu districts such as Chennai, Tiruvallur, Kancheepuram, and Chengalpattu
• Central regions, including Trichy, Thanjavur, and Ariyalur
• Southern belts, particularly Ramanathapuram, Thoothukudi, and Kanyakumari
• Western ghats, where isolated heavy spells are likely

The IMD notes that this pattern is associated with moisture convergence over the Bay of Bengal and a developing low-pressure influence expected to enhance rainfall intensity.

Chennai Braces for Worsening Weekend Weather

Residents of Chennai should prepare for a notable increase in rainfall by Friday and Saturday, with:

• Heavier showers
• Waterlogging concerns in low-lying areas
• Slower traffic movement
• Possible disruptions in suburban transit

While early-week rainfall is expected to be mild to moderate, weather models suggest a stronger system approaching the coast, bringing enhanced showers toward the weekend.

IMD Alerts & Advisory

The IMD has advised citizens to:

• Stay updated on official rainfall alerts
• Avoid flood-prone roads during peak rain hours
• Secure outdoor items and ensure drainage pathways are clear
• Follow alerts issued by Chennai Corporation and state disaster management authorities

Fishermen along coastal Tamil Nadu have been cautioned against venturing into rough seas later in the week as wind speeds may increase.
