An Dehradun weather alert from the India Meteorological Department warns of thunderstorms with lightning and gusty winds across Uttarakhand from April 28 to May 2, 2026. The bulletin, issued by IMD’s Dehradun centre, lists Dehradun, Haridwar, and surrounding districts in the affected zone.
The current run of warm weather will break first. Dehradun recorded 37.5 degrees Celsius on April 24, which is 3.5 degrees above the seasonal normal. Partly cloudy skies on April 25 and 26 are now giving way to a wider unstable system arriving by April 28.
What the Dehradun weather alert covers
Thunderstorms in this period bring three risks. Lightning strikes, sudden gusty winds touching 50 to 60 kilometres per hour, and intermittent heavy rain spells of 10 to 30 millimetres in short bursts. Hail is possible in higher elevation pockets above 1,500 metres, including Mussoorie and Chamba.
If you live in Dehradun’s Rispana or Bindal floodplain areas, watch drainage. Even moderate rain can flood low-lying lanes near the river beds. Park vehicles on higher ground.
Detailed forecast for Dehradun
For April 27, expect partly cloudy skies with a high near 35 degrees and a low of 22. April 28 brings the first thunderstorm window, most likely between 3 PM and 7 PM. April 29 and 30 carry the strongest storm probability, with gusty winds and lightning expected through the afternoon and evening. May 1 and 2 see lingering instability before clearer skies return on May 3.
Safety steps for the next five days
Lightning is the deadliest part of these storms. India loses more than 2,000 lives a year to lightning strikes, with Uttarakhand among the affected states. If you hear thunder, stay indoors. If you are caught outdoors, avoid trees, water bodies, and open ground. Squat low with feet together until the storm passes.
Unplug sensitive electronics during severe spells. Surge damage from direct or nearby strikes is the most common insurance claim during these systems. Charge your phone in advance. Power cuts of 30 minutes to two hours are typical during heavy lightning.
