Overview
- Pre-monsoon showers and thunderstorms prompted yellow or orange IMD alerts for Delhi, Mumbai and more than 60 districts of Uttar Pradesh on Sunday, May 31.
- Rain and gusty winds drove daytime highs down in Delhi by as much as 9.4°C at some stations and temporarily improved the city’s air quality into the 'satisfactory' range.
- Mumbai saw the season’s first pre-monsoon showers with highly localised heavy pockets and BMC gauges reporting up to about 27–35 mm in some suburbs.
- Heavy downpours in Uttarakhand led authorities to temporarily suspend the Kedarnath yatra and strand hundreds of pilgrims before rescue teams evacuated people and restrictions were eased.
- The IMD attributes the spell to a western disturbance plus moisture inflow, expects showers to linger into early June before weakening, and forecasts the southwest monsoon will likely deliver roughly 90% of the long‑period average with implications for water and crop planning.
