Live Tamil Nadu Rain Alerts & Weather Status: All 38 Districts Emergency Tracker

Northern Tamil Nadu—particularly the high-density industrial and agricultural corridors of the Ranipet District—is highly vulnerable to sudden, extreme atmospheric shifts. Bordered by Vellore, Kanchipuram, Tiruvannamalai, and Thiruvallur, this geographic basin undergoes intense meteorological transitions during both the Southwest and Northeast Monsoon seasons.

When low-pressure systems form over the Bay of Bengal, they often carry high-velocity winds and intense monsoonal rainfall straight through the Palar River basin, causing rapid water rises in key local reservoirs like the Polipakkam and Keezhveeranam lake networks.

During these critical weather events, search traffic spikes dramatically as residents, students, and commuters search for real-time safety advisories. These searches typically focus on official school, college, and administrative holiday announcements, which are issued directly by the Ranipet District Collector, N. Priya, IAS.

To keep the local community safe and informed, the automated dashboard below tracks live conditions across Ranipet’s core Revenue Divisions and its six administrative Taluks: Walajapet, Arcot, Kalavai, Sholinghur, Arakkonam, and Nemili.

For coordinates in the northern Tamil Nadu basin, such as Arakkonam ($12.93^\circ\text{ N} \mathbin{,} 79.34^\circ\text{ E}$), summer conditions also bring intense heat waves. To track heat safety, the live system is configured to fetch apparent temperature ratings ($AT$) directly via the high-resolution Open-Meteo API. The apparent temperature combines ambient temperature ($T$ in Celsius), relative humidity ($RH$), and wind speed ($w$ in m/s) to accurately gauge heat risk:

$$AT = T + 0.33 e – 0.70 w – 4.00$$

Where vapor pressure ($e$ in hPa) is derived from relative humidity:

$$e = \frac{RH}{100} \times 6.105 \exp\left(\frac{17.27 T}{237.7 + T}\right)$$
