With the IMD issuing an orange alert for heavy to very heavy rains, residents face slippery roads and potential flooding. This update was made on the evening of December 2. It covers the latest forecasts and impacts. It also outlines safety measures for USA-based Tamil diaspora and global followers.
What Happened: Timeline of Cyclone Ditwah’s Impact
Cyclone Ditwah intensified over the weekend, making landfall near Puducherry on November 30, 2025, before weakening into a deep depression. By December 1, it hovered 50 km east of Chennai, triggering continuous downpours across northern Tamil Nadu.
Key events:
- December 1: Schools closed in Chennai, Tiruvallur, and Chengalpattu amid heavy rains. Waterlogging was reported on major roads like Anna Salai and Egmore.
- December 2: Rains lashed Madurai and Chennai. IMD forecasted very heavy showers till evening. Gusty winds were expected up to 60 km/h. Three deaths confirmed from drowning and tree falls.
- December 3 Outlook: Depression to move inland toward ghat areas, bringing moderate to heavy rain in Chennai till morning.
The system has boosted Tamil Nadu’s seasonal rainfall above normal (37.1 cm vs. 36.1 cm), reducing Chennai’s deficit to 8% (62 cm received vs. 67 cm normal).
Official Updates
The Regional Meteorological Centre (RMC) Chennai issued an orange alert for December 2–3. It warned of heavy rains in Tiruvallur, Chennai, Ranipet, Kancheepuram, and Chengalpattu. District collectors announced holidays: Chennai’s Rashmi Siddharth Zagade urged students to “eat, study, sleep, and repeat” safely.
Tamil Nadu Disaster Management Minister K.K.S.S.R. Ramachandran confirmed three deaths and deployed NDRF teams for relief. Revenue Minister announced ₹20,000/ha compensation for October rain-damaged crops, extending aid to current victims. Winds of 40–60 km/h persist; fishermen advised off seas till December 3.
Public and Fan Reaction
Social media overflowed with frustration over waterlogging. #ChennaiRains and #CycloneDitwah trended on X with 200K+ posts, featuring videos of flooded streets and stranded vehicles. Commuters shared: “Anna Salai looks like Venice – minus the gondolas!” amassing 15K likes.
Parents praised holiday decisions: “Safety first – thanks for the heads-up.” USA-based Tamil communities on Reddit and Facebook organized virtual prayer chains for victims. Criticism targeted infrastructure: “Potholes + rain = disaster waiting,” one viral thread noted, with 50K views. Overall, reactions blend relief at precautions with calls for better drainage.
Analysis: Impacts and Long-Term Outlook
Cyclone Ditwah’s slow movement (3 km/h) prolonged Chennai’s ordeal, exacerbating urban flooding in low-lying areas like Egmore and Kodambakkam. Economically, traffic snarls disrupted daily commutes, while agriculture benefits from excess rain but risks crop damage in coastal zones.
Broader view: This follows a wetter-than-normal northeast monsoon. Chennai’s AQI stays “good” (thanks to rain) at 50–70. However, humidity at 80% adds discomfort. Experts warn of recurring issues without drainage upgrades; December 4–5 may see more patchy showers. For USA travelers, flights from MAA remain operational but delayed – check IndiGo/Air India apps.
Conclusion
As of December 2, 2025, Chennai’s rain saga from Cyclone Ditwah continues. School holidays are on December 3. There are alerts for heavy showers. Waterlogging persists, but proactive closures prioritize safety amid three confirmed deaths.
Stay indoors, monitor IMD apps, and support relief efforts – Chennai’s resilience shines through storms. Brighter, drier days ahead post-December 3.
