IMD Issues Rainfall Warning for July 19 as Humidity Levels Spike
🌧️ Weather Overview
Chennai is bracing for heavy rainfall today, July 19, 2025, as the India Meteorological Department (IMD) has issued a yellow alert for the city and surrounding coastal areas of Tamil Nadu. The downpour is being driven by active monsoon currents from the Bay of Bengal, accompanied by overcast skies and rising humidity.
🌡️ Key Highlights
- Rainfall Intensity: Moderate to heavy showers expected throughout the day.
- Humidity Levels: Likely to cross 85%, making it muggy and uncomfortable in the afternoon.
- Temperature: Daytime highs expected to hover around 31–33°C, with a real-feel temperature of over 38°C due to humidity.
- Wind Speed: Gusty winds between 25–35 km/h may accompany the showers.
⚠️ IMD Advisory
- Citizens are advised to carry umbrellas or raincoats and avoid waterlogged areas.
- Motorists are urged to drive cautiously due to slippery roads and poor visibility.
- Local authorities have been asked to remain alert and monitor urban flooding hotspots.
🛑 Possible Disruptions
- Traffic congestion in key areas like T Nagar, Velachery, and Mount Road.
- Delays in suburban train services and Metro operations during peak rainfall periods.
- School and office commute could be impacted; residents advised to leave early or work remotely if possible.
📍 Broader Forecast for Tamil Nadu
The IMD has forecast similar monsoon conditions for coastal districts such as Cuddalore, Puducherry, Chengalpattu, and Nagapattinam. Interior districts may see scattered showers by evening.
🌍 Climate Context
Weather experts say this rainfall pattern aligns with the monsoon trough shifts expected in late July. Chennai typically receives 10–12 cm of rain during this phase, and this year’s intensity is attributed to the interaction between monsoon winds and a developing low-pressure area in the Bay of Bengal.
