Early morning storms have formed over the northern suburbs of Chennai and Thiruvallur, bringing the possibility of rain showers across several areas within the next one hour. According to local weather trackers and real-time satellite data, these rapidly developing thunderclouds may lead to moderate to heavy rainfall in pockets of north Chennai, Ambattur, Madhavaram, and surrounding zones in Thiruvallur district.
This sudden weather shift comes as part of the ongoing monsoon dynamics affecting Tamil Nadu, especially with active convection zones forming across Vellore and nearby regions. The storms near Vellore are also expected to move eastward, possibly intensifying rainfall in interior Tamil Nadu by afternoon.
Residents in Chennai, particularly in the northern belt, should remain alert for quick rain spells, slippery roads, and potential traffic disruptions. The IMD has not yet issued a formal alert, but local weather bloggers confirm increased atmospheric instability this morning.
These early Chennai rains are a welcome sign for water resource improvement, especially in key reservoirs like Poondi, Red Hills, and Chembarambakkam. Citizens are advised to keep umbrellas handy and check for real-time Chennai rain alerts.
