Kerala wakes to a higher rain alert today, September 22, as the India Meteorological Department tightens district warnings after a turbulent Monday. Thunderstorms with gusty winds and even cloudbursts remain on the table, especially across the central belt. Coastal advisories continue for mariners. Commuters, students and travellers should check local updates before heading out, because alerts are being refined through the day.
IMD’s Day‑2 district map, issued at 2100 IST on September 21, flags orange alerts in Kottayam, Idukki, Ernakulam, Thrissur, Palakkad and Malappuram for today. The rest remain on yellow watch. Monday’s IMD‑KSDMA bulletin centred yellow over Thiruvananthapuram, Kollam, Pathanamthitta and Alappuzha, with northern districts trending active mid‑week. Treat colours as dynamic; recheck the live IMD map and district control‑room posts through the day.
IMD rain alerts Kerala: timeline, thunderstorm and gusty wind windows
Nowcasts, issued every three hours, are crucial today. Recent IMD windows flagged the central stretch for thunderstorms with surface winds near 30–40 kmph. Use the Thiruvananthapuram radar and the District‑Wise Warnings page to time journeys, especially across ghat roads and low‑lying corridors. Expect short, intense bursts rather than day‑long rain; add buffer time for inter‑city travel and logistics.
City watch: Kochi, Thiruvananthapuram, Kozhikode
Urban signals are mixed. IMD city forecasts for September 22 show one or two spells but no formal warning for Kochi, Thiruvananthapuram Airport and Kozhikode. Localised downpours can still trigger quick waterlogging on arterial stretches and around transit hubs. Heavy cells often pass fast; check real‑time feeds before airport runs and leave margin for rail signalling or platform delays during bursts.
Fishermen advisories, hill/ghat risks and travel watch
Sea state stays rough. KSDMA warns of 35–45 kmph winds, gusting to 55 kmph, along the Kerala–Karnataka–Lakshadweep coast today, with stronger squalls over the Bay. “The possibility of cloudbursts is also high in Kerala,” IMD’s Neetha K Gopal cautioned, underscoring landslide risk on Idukki–Wayanad ghats. Rain holidays are decided by District Collectors; expect evening or early‑morning notices on official pages.
