IMD weather alert issued for Delhi-NCR, Uttar Pradesh, Madhya Pradesh, and Bihar as a low-pressure system triggers heavy rainfall.

Heavy Rain Alert Across North and Central India as Low Pressure Area Intensifies

New Delhi, August 10, 2026 — The India Meteorological Department (IMD) has issued fresh weather alerts for large swathes of North and Central India as a low-pressure system over southwest Uttar Pradesh and an active monsoon trough continue to drive widespread precipitation. Delhi-NCR, Uttar Pradesh, Madhya Pradesh, Bihar, and parts of Himachal Pradesh are bracing for moderate to heavy rainfall over the coming days, with several major rivers already breaching or flowing near critical danger thresholds.

Current Weather System & Bay of Bengal Outlook

The primary driver of the current wet spell is a low-pressure area situated over southwest Uttar Pradesh and its neighborhood, operating in tandem with the monsoon trough. This synoptic feature is triggering intense rainfall, thunderstorms, and gusty surface winds ranging between 50 to 60 kmph (with higher gusts in isolated pockets).

Additionally, meteorologists project that another low-pressure system will form near the northern Bay of Bengal around August 13, 2026. This secondary system is expected to reinvigorate monsoon activity across eastern coastal and inland states including West Bengal, Odisha, Bihar, and Jharkhand.

Delhi-NCR Weather Update: Waterlogging and Gusty Wind Forecast

In the National Capital Region (NCR), rain lashed several localities on Monday afternoon, delivering significant relief from stifling humidity. The Mayur Vihar weather station recorded 37 mm of rainfall by early afternoon, followed by moderate spells across Ridge, Lodhi Road, and Safdarjung observatories.

Rainfall in Delhi-NCR brought relief from humidity, though waterlogging was reported in low-lying urban pockets.

The IMD projects intermittent light to moderate showers continuing through August 15–16, interspersed with isolated intense downpours and lightning. Strong surface winds up to 60 kmph are likely during thunderstorm activity. While temperatures have dropped sharply, municipal authorities have deployed dewatering pumps to clear waterlogging along key traffic corridors.

Uttar Pradesh: Ganga, Yamuna & Ghaghra Rivers Flow Above Danger Mark

Monsoon activity remains severe across western and eastern Uttar Pradesh. Heavy downpours have swollen major river basins, causing localized flooding in riparian districts.

According to official hydrological reports from the Central Water Commission (CWC), over ten major rivers—including the Ganga, Yamuna, Sharda, Ghaghra, and Saryu—are flowing near or above their official danger marks:

• The Ghaghra River has crossed the danger threshold in Barabanki district.
• The Ganga River is flowing above the danger level in Kaushambi.
• The Sharda River has breached warning limits in Lakhimpur Kheri.

Districts such as Lalitpur and Mahoba remain under heavy to very heavy rainfall alerts, while yellow warnings remain active across central UP.

Madhya Pradesh & Bihar: Dindori School Closures & Yellow Alerts

In Madhya Pradesh, continuous downpours forced the Dindori district administration to order a complete closure of all government and private schools (from Nursery to Class 12) on Monday.

The Narmada river in Mandla crossed danger mark following heavy downpours in upper catchments of Madhya Pradesh.

In Mandla district, the Narmada River has crossed its danger mark, inundating low-lying ghats and bridges. Orange alerts for heavy rain remain in force for Bhopal, Raisen, Sehore, and surrounding districts of western Madhya Pradesh.

Meanwhile in Bihar, IMD has sounded a yellow alert across 20 districts, warning residents against frequent cloud-to-ground lightning strikes and sudden localized squalls.

What to Expect (August 10–15, 2026) & Official Safety Advisory

With monsoon dynamics remaining vigorous over northern and central zones, meteorologists recommend the following timeline and precautions:

• August 10–12: Peak rainfall activity across UP, MP, and Delhi-NCR with gusty winds and river level monitoring.
• August 13–15: Secondary Bay of Bengal low-pressure system takes shape, shifting major rainfall density toward East India (Bihar, Jharkhand, Odisha, West Bengal).
• Hilly Terrain Caution: Landslide and flash flood risks remain elevated in Himachal Pradesh and Uttarakhand; several state highways remain closed.
