Overview
- The India Meteorological Department says a persistent low over Saurashtra is keeping rain and thunderstorms over large parts of the country and has led to yellow and orange district warnings in sections of West Bengal this week.
- An upper‑air cyclonic circulation over north Thailand is forecast to move into the north Andaman Sea and is likely to spawn a fresh low around September 19 that may intensify and track toward the south Odisha–north Andhra coast over several days.
- The IMD says the southwest monsoon will begin withdrawing from parts of west Rajasthan around September 19 even as coastal, eastern and southern states stay under active rain threats for days to come.
- In the United States, multiple upper‑level and surface systems will bring rounds of heavy rain, thunderstorms and gusty winds to the Midwest, Minnesota, Chicago area, Detroit and Florida this weekend with localized flooding and travel disruptions expected, and the National Hurricane Center rates short‑term Atlantic tropical odds as low.
- Seasonal factors such as El Niño and slow‑moving storm trains are helping concentrate heavy downpours, raising the risk of flash flooding, coastal swells and hazardous rip currents so residents should follow local warnings and be prepared for sudden, intense rainfall.
