Fresh India Meteorological Department alerts this morning, Saturday, September 12, highlight heavy rain risk across east‑central belts. Odisha, Chhattisgarh and Coastal Andhra Pradesh stay in focus, while Bengaluru watches evening convection windows. Kerala’s coast faces high waves tonight, and Delhi‑NCR keeps a light rain chance with muggy air. Expect patchy airport, highway and urban drainage disruptions during peak hours.
IMD centre updates point to south Odisha remaining rain‑loaded as the system drifts inland. Recent bulletins flagged Nabarangpur, Rayagada, Koraput, Gajapati and Ganjam; monitor today’s district colour map for escalation windows. Chhattisgarh’s Raipur carries a “thunderstorm with lightning” signal. North Coastal Andhra turns wetter, with Srikakulam, Vizianagaram, Manyam, ASR, Visakhapatnam, Anakapalle and Kakinada primed for showers. Plan detours where hill roads and low culverts converge.

IMD today: Odisha, Chhattisgarh, Coastal Andhra alerts
For travellers, colour codes matter. Orange signals “be prepared”; yellow means “watch and stay updated.” Keep an eye on Raipur’s thunder probabilities and Amaravati’s thunderstorm, lightning and strong wind guidance through the evening band. Short, intense bursts can exceed roadside drainage capacity within minutes, so prioritise early departures and avoid narrow valley stretches after dusk.
Bengaluru thunderstorms: commute hotspots
IMD’s Bengaluru city forecast shows generally cloudy skies with light rain and no warning today. Yet three‑hour nowcasts often trigger quick evening cells. Watch underpasses and chokepoints around Silk Board, KR Puram, Hebbal, Manyata approaches and HBR Layout, where ponding slows traffic. Use MAUSAM and Damini for push alerts before leaving office districts.
Kerala high‑wave advisory and fisherfolk caution
Kerala State Disaster Management Authority warns of 0.5 to 1.2 metre high waves along the coast, valid till 11:30 pm on Sunday, September 13. Expect beach run‑up at vulnerable stretches and possible port slowdowns during the late‑evening tide. Avoid shore fishing, beach driving and rock‑ledge selfies; heed local harbour notices tonight and tomorrow.
Delhi‑NCR light rain and humidity outlook
Urban Meteorological Services indicate no colour warning for Delhi‑NCR today, though a generally cloudy day with light to moderate rain is on the cards. Expect sticky conditions between spells. Flyers should watch for minor flow control at peak arrival banks; road users should budget slack near underpasses prone to slow drainage.
What to do now: verify your district colour on IMD’s map, then track three‑hour nowcasts before starting longer drives. Bhubaneswar, Visakhapatnam and Raipur airports may see brief convective delays during evening peaks. Rail travellers should check updates for low‑lying sections. Keep umbrellas stowed, electronics dry‑bagged, and alerts enabled on MAUSAM and Damini apps.
