Weather Update, August 27, 2026: The India Meteorological Department (IMD) has forecast another active spell of monsoon weather across several parts of the country on Thursday, with heavy rain, thunderstorms, lightning and strong winds expected in multiple regions.

However, the latest official IMD bulletin does not support a blanket claim that 14 states will receive “torrential rain and storms within seven hours.” Instead, the national forecast shows different levels of rain and thunderstorm risk across several states and meteorological subdivisions through August 27.

The most significant rain risk is concentrated over parts of Uttar Pradesh, Bihar, Madhya Pradesh, Jharkhand, Chhattisgarh, Odisha, northeastern India and the Himalayan region.

Heavy Rain Likely in Several Parts of India

According to the IMD’s August 26 night bulletin, heavy rainfall at isolated places is likely on August 27 over Uttar Pradesh, Bihar, Madhya Pradesh, Chhattisgarh, Jharkhand and Odisha.

Heavy rain is also forecast at isolated locations over Arunachal Pradesh, Assam and Meghalaya, Nagaland, Manipur, Mizoram and Tripura, Sub-Himalayan West Bengal and Sikkim, as well as Kerala and Mahe.

The warning means that not every district in these regions will receive intense rainfall. Heavy rain may occur in isolated pockets, while nearby locations could see lighter or intermittent showers.

Uttar Pradesh Remains Under Rain Watch

Uttar Pradesh continues to be one of the areas requiring close attention.

The IMD expects heavy rainfall at isolated places over both western and eastern parts of Uttar Pradesh on August 27. East Uttar Pradesh is also likely to see fairly widespread to widespread rainfall.

A separate flash-flood outlook has identified a low to moderate risk in parts of West Uttar Pradesh, particularly around Auraiya, Hamirpur and Jhansi, through the period ending August 27 evening.

The warning points to the possibility of surface runoff and temporary inundation in low-lying areas where the ground is already saturated.

Residents in vulnerable districts should keep track of local warnings because rainfall intensity can differ considerably within short distances.

Madhya Pradesh Faces Heavy Rain and Flash-Flood Risk

Madhya Pradesh is another state where weather conditions remain unsettled.

The IMD has forecast heavy rainfall at isolated places over both eastern and western Madhya Pradesh on August 27, while thunderstorms and lightning are also possible in parts of the state.

The flash-flood outlook includes several districts.

In East Madhya Pradesh, the risk area includes Chhatarpur, Chhindwara, Tikamgarh, Damoh, Jabalpur, Katni, Narsinghpur, Panna and Sagar.

In western parts of the state, Ashoknagar, Bhind, Datia, Guna, Gwalior, Narmadapuram, Shivpuri and Vidisha are among the districts mentioned in the outlook.

People living close to streams, drainage channels and low-lying roads should be particularly cautious during intense showers.

Bihar, Jharkhand and Odisha Could See Thunderstorms

Rainfall activity is also expected to remain strong across eastern India.

Heavy rain is likely at isolated places over Bihar, Jharkhand and Odisha on August 27.

The IMD has additionally forecast thunderstorms accompanied by lightning and gusty winds of around 30-40 kmph at isolated locations across Bihar, Jharkhand, Odisha and West Bengal-Sikkim.

Such conditions can lead to localised waterlogging, temporary disruption to road traffic and lightning-related risks.

People working outdoors should avoid open fields and exposed locations when thunderstorms develop.

What Is the Forecast for Rajasthan?

The latest forecast for Rajasthan is more limited than some circulating reports suggest.

The IMD's Jaipur centre has issued a thunderstorm and lightning warning for parts of East Rajasthan on August 27, but its subdivision-wise warning does not indicate widespread heavy rainfall across the state for the day. West Rajasthan has no warning listed for August 27 in the latest bulletin.

The national IMD bulletin also mentions isolated thunderstorms and lightning over East Rajasthan on August 27.

Therefore, claims of a widespread yellow alert for heavy rain across Rajasthan should be treated carefully unless supported by a newer district-specific bulletin.

Delhi May See Rain, but No Nationwide IMD Heavy-Rain Warning for the Capital

Delhi and adjoining Haryana recorded rainfall activity on August 26, according to the IMD’s observations.

However, the latest national Day-2 warning for August 27 does not list Haryana-Chandigarh-Delhi among the regions under an isolated heavy-rainfall warning.

This does not mean Delhi will remain completely dry. Local showers or thunderstorms can still occur, and residents should check the latest city-specific nowcast before travelling.

The distinction is important because a general possibility of rain is different from an official heavy-rain warning.

Uttarakhand and Other Hill Areas Need Extra Caution

The Himalayan states continue to face weather-related risks.

The IMD expects fairly widespread to widespread rainfall over Uttarakhand through the coming days, with isolated thunderstorms and lightning also possible on August 27.

Heavy rainfall is forecast over Uttarakhand again later in the period, particularly from August 30 into early September.

Because even moderate-to-heavy rain can trigger landslides or falling rocks on unstable slopes, travellers should remain cautious on mountain highways.

Weather conditions in hill areas can deteriorate quickly, particularly near landslide-prone stretches and swollen streams.

What Is Driving the Current Weather?

Several active weather systems are influencing the monsoon.

The IMD says a low-pressure area over southeast Uttar Pradesh and adjoining areas remained active on August 26, with an associated cyclonic circulation extending into the atmosphere.

The monsoon trough was passing through Jammu, Dehradun, southeast Uttar Pradesh, Daltonganj and Digha before extending towards the northeast Bay of Bengal.

A trough also extended from the low-pressure system across East Madhya Pradesh, Chhattisgarh and Odisha. In addition, cyclonic circulations were present over north Haryana, Northeast Assam and northwest Madhya Pradesh.

Together, these systems are supporting moisture convergence and widespread rainfall activity across central, eastern and northeastern India.

Thunderstorms and Strong Winds Also in the Forecast

Rain is not the only concern.

The IMD has warned of thunderstorms accompanied by lightning over parts of Arunachal Pradesh, Assam, Meghalaya, Chhattisgarh, East Rajasthan, Madhya Pradesh, the northeastern states and Uttarakhand.

Andhra Pradesh and Tamil Nadu-Puducherry-Karaikal may see gusty winds reaching 40-50 kmph, while Bihar, Jharkhand, Odisha and West Bengal-Sikkim could experience winds of around 30-40 kmph during thunderstorms.

Over the Andaman and Nicobar Islands, thundersqualls with winds reaching 50-60 kmph are also possible.

Safety Advice for Residents and Travellers

People in rain-affected areas should monitor district-level IMD nowcasts rather than relying only on broad national forecasts.

Avoid sheltering under trees, electric poles or weak structures during thunderstorms. Travellers in hill regions should check road conditions before starting their journey, particularly where landslides have occurred recently.

Farmers should secure harvested crops and avoid working in open fields during lightning activity.

Those living in low-lying neighbourhoods should remain alert for sudden waterlogging, especially in districts included in the flash-flood outlook.

The most important point for August 27 is that heavy rain is likely in several regions, but the intensity and warning level vary considerably from state to state. The IMD’s official bulletins remain the most reliable source for local alerts, especially as monsoon weather can change quickly.

Note: IMD warnings are updated several times a day. Forecasts mentioned here are based on the latest national bulletin available for August 27, 2026, and local conditions may change with subsequent nowcasts.
