Heavy Rain Forecast in 13 Tamil Nadu Districts – IMD Issues Thunderstorm Alert with Lightning and Winds

The India Meteorological Department (IMD) has issued an important weather warning for Tamil Nadu, cautioning the public about widespread heavy rain, thunderstorms, lightning, and gusty winds in several regions of the state. As per the latest weather bulletin, at least 13 districts are expected to experience intense rainfall today, with a similar pattern likely to continue tomorrow as well.

What’s Causing the Rain?

The current rainfall activity is attributed to a combination of upper atmospheric circulation and a low-pressure zone developing over the Bay of Bengal region. These weather systems have been influencing Tamil Nadu’s climate for the past few days, resulting in a sudden shift from dry summer conditions to moderate to heavy showers.

According to the IMD, winds reaching speeds up to 40 km/h may accompany the rains, particularly in interior districts. Thunderstorms and lightning activity are also expected, increasing the risk of flash flooding, power outages, and waterlogging in low-lying areas.

Districts Under Rain Watch Today

The following districts are under a heavy rain alert today:

• Thanjavur
• Thiruvarur
• Nagapattinam
• Mayiladuthurai
• Pudukkottai
• Ariyalur
• Perambalur
• Trichy
• Salem
• Kallakurichi
• Dharmapuri
• Krishnagiri
• Tirupattur

The Union Territory of Karaikal is also expected to receive moderate to heavy rainfall due to its proximity to the affected zones.

Weather Forecast for Chennai

In Chennai, the skies will remain partly cloudy throughout the day. Light rain or drizzles may occur in a few parts of the city, especially during the evening hours. While the rainfall may not be intense, residents should remain cautious of slick roads and minor traffic slowdowns.

Temperature Drop Expected

The IMD has also predicted a gradual drop in maximum temperatures across Tamil Nadu over the coming days. From now until May 20, the mercury could drop by 2–3 degrees Celsius, providing slight relief from the heatwave-like conditions that prevailed earlier this month.

Safety Tips During Thunderstorms

• Avoid going outdoors during heavy rainfall and thunderstorms.
• Stay away from trees, electric poles, and metal structures during lightning.
• Keep mobile phones and electronics unplugged during stormy weather.
• Drive carefully on wet roads and watch out for waterlogged zones.
• Follow IMD alerts and local advisories via official sources.

Local authorities in affected districts have been alerted, and precautionary steps are being taken to prevent flooding and ensure public safety. Citizens are encouraged to stay informed through reliable news sources and weather apps.

Final Note

The weather in Tamil Nadu remains unpredictable due to shifting wind patterns and evolving pressure systems. The state government is closely monitoring the situation, especially in coastal and delta districts where heavy rainfall is expected. Keep umbrellas and rain gear handy, and stay safe during these intense weather conditions.
