IMD warns of thunderstorms and heavy rain across 15 Indian states within 12 hours

Indian media reports said the India Meteorological Department issued a short-term weather warning for thunderstorms, heavy rain and gusty winds across 15 Indian states within 12 hours.

The reports said wind speeds could reach up to 70 km/h in some areas. Delhi-NCR, Uttar Pradesh, Bihar, Rajasthan, West Bengal, Kerala and Tamil Nadu were among the regions named in coverage.

What the alert said

Navbharat Times first reported the 15-state, 12-hour warning on June 29, 2026. Later coverage from Times of India and Economic Times said IMD was also forecasting rain, thunderstorms and gusty winds across several regions as the southwest monsoon advanced.

Those reports described the weather pattern as affecting northern, eastern, central and southern India, with yellow alerts issued in multiple regions.

Broader weather backdrop

The reports placed the alert in the middle of an active monsoon phase at the end of June. Economic Times said Delhi-NCR, including Delhi, Noida and Gurugram, could see showers and some relief from heat.

Times of India also reported an increased flash-flood risk in parts of northeastern and eastern India.

Why it matters

The warning is relevant for commuters, residents and local authorities because thunderstorms, lightning and gusty winds can disrupt travel and outdoor activity. Heavy rain also raises the risk of localized flooding in vulnerable areas.

What to watch next

Further updates may clarify whether IMD issues a more specific state-wise bulletin, whether any areas move from yellow to orange or red alerts, and whether the weather warning leads to flooding, transport disruption or other impacts.
