Chennai and several Tamil Nadu districts are witnessing intensified rainfall, with the IMD issuing a yellow alert. Triggered by an easterly wave over the Bay of Bengal, the downpour has disrupted daily life and is expected to continue for the next few days. Authorities urge caution as monsoon-like conditions persist.

Key Highlights

Heavy Rainfall Alert: The India Meteorological Department (IMD) has sounded a yellow alert for Chennai and nine Tamil Nadu districts, warning of heavy rainfall at isolated locations.
Weather System: The showers are being driven by an easterly wave and trough over the southwest Bay of Bengal, off the Sri Lankan coast, which is pushing moisture inland.
Local Impact: Continuous rain since early Sunday has affected areas like Kodambakkam, Choolaimedu, Vadapalani, Koyambedu, Nungambakkam, and Thousand Lights, disrupting traffic and daily routines.
Districts Affected: Apart from Chennai, districts including Tiruchi, Perambalur, Kallakurichi, and Tiruvannamalai are expected to receive significant rainfall over the next 48 hours.
Duration: Meteorologists forecast that the wet spell will persist until January 26, with intermittent heavy showers and thunderstorms.

What’s Behind the Downpour?

The current spell of rain is unusual for January, typically a dry month in Tamil Nadu. Experts attribute the phenomenon to unseasonal easterly winds interacting with moisture-laden clouds over the Bay of Bengal. This has created monsoon-like conditions, leading to widespread showers across coastal and interior districts.

Such weather systems are not uncommon but often catch residents off guard. The Regional Meteorological Centre (RMC) has clarified that while the intensity resembles monsoon rains, this is a short-term weather disturbance rather than a seasonal shift.

Impact on Daily Life

Commuters: Waterlogging and traffic snarls have been reported in several parts of Chennai.
Schools & Offices: As of now, no official closure orders have been issued, though authorities are monitoring conditions.
Residents: The showers have brought temporary relief from humidity, but the risk of flooding in low-lying areas remains.

Why It Matters

Tamil Nadu’s vulnerability to extreme weather events has grown in recent years, with unseasonal rains disrupting urban infrastructure. The current spell highlights the need for better drainage systems, preparedness, and climate resilience planning. For Chennai, which often struggles with waterlogging, these rains are both a blessing and a challenge.
