IMD Flags Thunderstorms From 24 Sep and Heavy Rain Into Late Week Over East UP

The India Meteorological Department’s East Uttar Pradesh warning table, issued on 22 September, keeps Tuesday and Wednesday clear of alerts and then builds a thunderstorm-to-heavy-rain sequence through the rest of the week.

For 22 and 23 September the East UP row shows “No warning.” From 24 September the product flips to thunderstorm and lightning with squall risk. From 25 through 28 September the same subdivision carries a heavy-rain tag layered on thunderstorm, lightning and squall language. Varanasi and the wider Purvanchal belt sit inside that East UP coverage.

The table is a forecast product, not an observation sheet. It does not replace the half-hourly METARs from Babatpur, which on Tuesday morning still showed mist and modest temperatures. What it does is flag the days when outdoor plans, ghat work and low-lying traffic should assume convective weather rather than a quiet late-monsoon lull.

Heavy rain in IMD’s colour language usually means a step up from light scattered showers — enough to waterlog poorly drained stretches, slow the Cantt–airport road and push fresh silt toward already messy ghat steps if the Ganga’s local drains back up. Squall and lightning groups add a short-fuse wind and safety risk for open-field labour and for anyone on two-wheelers when a cell rolls through.

West Uttar Pradesh’s companion table on the same page is quieter on 24 September and picks up thunderstorm language from 25 September, with heavy rain later in the window. That split matters for travellers crossing from Lucknow-side districts into Banaras: the eastern subdivision turns active a day earlier on this issue cycle.

IMD updates these subdivision warnings daily. A calm 22–23 September does not lock the weekend; a revised chart on Wednesday could trim or extend the heavy-rain stretch. For now the official East UP line is plain: no warning for the next two calendar days, thunderstorm risk from the 24th, and heavy rain in the frame from the 25th through the 28th.

Municipal drainage crews and temple-town event planners typically treat such a sequence as a cue to clear silt traps and check pump points before the first thunderstorm day. Farmers watching standing crop in the district’s fringe blocks will read the same chart as a moisture opportunity wrapped inside a lodging and flood risk if falls turn sharp.

Until later METARs or a city observatory sheet show an actual wet spell, Tuesday’s airport mist remains the observed weather. The IMD table is the forward look — and for East UP that look turns unsettled from midweek.

Boat operators still waiting for calmer Ganga flow will read the midweek thunderstorm tag with caution: a sharp cell can raise local runoff into ghats even when the main gauge is falling. Travellers holding Cantt tickets for Thursday onward should keep an eye on revised IMD charts and on live train running status if lightning slows yard work.
