IMD Warns of Severe Weather with Heavy Rainfall in Tamil Nadu and Surrounding Areas Until October 21

The India Meteorological Department (IMD) has issued a weather alert, warning of heavy to very heavy rainfall in Tamil Nadu and surrounding regions until October 21, 2024. The intense downpour is likely to impact coastal districts, parts of interior Tamil Nadu, and adjoining areas in Puducherry, Karnataka, and Kerala.

Key Reasons for Heavy Rainfall

The primary cause behind this extreme weather is attributed to a cyclonic circulation over the Bay of Bengal. This system has strengthened, drawing moist winds inland, leading to widespread rain and thunderstorms. The interaction of this system with northeast monsoon winds, which typically bring rainfall to Tamil Nadu during this period, has further intensified the situation.

Impacted Areas

According to IMD, the districts that will be most affected include:

• Chennai
• Kanyakumari
• Nagapattinam
• Cuddalore
• Thanjavur
• Madurai

In addition, flooding and waterlogging are possible in low-lying areas, particularly in urban zones like Chennai, where the city’s drainage system may struggle to cope with prolonged heavy rainfall.

Safety Precautions

The IMD has urged people in affected areas to remain cautious and take necessary precautions. Specific recommendations include:

• Avoid traveling to flood-prone areas, particularly during peak rain hours.
• Keep an emergency kit ready, including essentials like water, food, and first-aid.
• Those living in vulnerable areas, especially near rivers or lakes, should be prepared for potential evacuation orders.

Fishermen Advisory

A fishermen advisory has also been issued, cautioning against venturing into the Bay of Bengal during this period. The rough seas pose a significant risk, with strong winds expected to create hazardous conditions. Fishermen have been strongly advised to avoid fishing activities and secure their boats until conditions improve.

Potential Impacts on Daily Life

• Transportation: Heavy rain may lead to traffic disruptions, particularly in major cities like Chennai. Commuters should expect delays and consider using alternate routes or work-from-home options.
• Power Supply: Prolonged rainfall can result in power outages, especially in areas where electrical infrastructure is vulnerable to waterlogging.
• Agriculture: Farmers in Tamil Nadu are advised to take measures to protect standing crops, as the rain could result in crop damage.

Local Authorities’ Response

Local authorities are already on high alert and are working to ensure adequate disaster preparedness measures. Chennai Corporation and district administrations are closely monitoring vulnerable areas and making efforts to clear stormwater drains to minimize flooding risks. Emergency teams are being mobilized to address potential flooding and waterlogging.

Conclusion

The IMD’s severe weather alert calls for vigilance and preparedness in Tamil Nadu and nearby regions. With the potential for heavy rains and strong winds until October 21, residents and authorities alike must stay informed and take necessary precautions to mitigate the impact of this severe weather event.
