Residents of Chennai and several adjoining districts in Tamil Nadu are on high alert today as the India Meteorological Department (IMD) has raised the warning level to Orange for multiple zones. This signals the possibility of heavy to very heavy rainfall, potential waterlogging, thunderstorms and gusty winds. The situation demands awareness, prudence and timely action.
What’s happening?
A low-pressure area over the southwest Bay of Bengal has strengthened and is expected to drift slowly toward the Tamil Nadu coast. This meteorological development is triggering increased moisture inflow and atmospheric instability, leading to forecast heavy rainfall in the coastal and delta districts.
For the city of Chennai, the forecast for today is marked by intermittent rain, possible thunderstorms and an overcast sky. Temperatures are likely to hover around 26-28 °C with humidity remaining high.

What this means for you
Travel and outdoor plans: Consider postponing or altering non-essential travel especially during heavy rain spells.
Low-lying and flood-prone zones: These areas are vulnerable. Exercise caution, avoid wading through waterlogged roads and stay away from drains or open waters.
Schools, institutions and workplaces: Some districts have declared holidays or advised restricted outdoor activities in view of the alert. India TV News+1
Safety preparedness: Ensure mobile phones are charged, keep flashlights/torches ready, avoid parking under unstable trees or weak structures, and secure loose items outside.
Weather updates: Keep track of official bulletins, local district-collector advisories or municipal alerts.
Why this alert is significant
An Orange Alert from IMD means heavy rainfall is likely to occur at many places in the affected districts (unlike a Yellow alert which indicates lighter or fewer events). This elevates risks of flooding, traffic disruption, commuter delays, power or communication outages, and other weather-induced hazards. Mausam+1
Given Chennai’s urban geography, high-density population and existing drainage challenges, even moderate rain can lead to surface flooding and transport bottlenecks. The combination of heavy rain + slow drainage + continuing monsoon season means heightened vigilance is required.
Immediate tips for residents
Avoid going to sea/coastal waters: If you live near the coast, avoid venturing into open sea or near surf because rough sea conditions and gusty winds are likely. The Financial Express
Secure your roof, gutter and drainage: Clear any debris from balconies or choked drains; ensure rainwater can flow out easily.
Use public transport wisely: If roads show signs of waterlogging, opt for metro/train services where possible, or delay travel until conditions improve.
Protect health and safety: Wet and humid conditions can trigger respiratory problems, slippery surfaces cause falls — tread carefully.
Stay indoors during thunderstorms: Avoid open ground, tall trees or metal structures during lightning events.
