Monsoon activity remains intense across large parts of India, with several regions likely to experience another spell of heavy rainfall. The India Meteorological Department (IMD) has warned of heavy to very heavy rain, thunderstorms, lightning and gusty winds across parts of eastern, central, northern, western and northeastern India.

According to the weather outlook for August 13, 2026, Odisha and Gangetic West Bengal are among the regions where particularly intense rainfall is expected. Several other states could also see heavy showers during the day.

People living in vulnerable areas should keep track of local weather advisories, especially where thunderstorms, lightning, waterlogging or strong winds are expected.

Heavy to Very Heavy Rain Alert for Odisha and West Bengal

Weather conditions are expected to remain particularly active over eastern India on Thursday.

Odisha and Gangetic West Bengal could receive heavy to very heavy rainfall on August 13. Heavy rain is also expected at isolated places across several neighbouring regions.

These include Jharkhand, Sub-Himalayan West Bengal and Sikkim, Andaman and Nicobar Islands, Chhattisgarh, East Madhya Pradesh, West Madhya Pradesh and Vidarbha.

Thunderstorms accompanied by lightning may also develop over parts of West Bengal, Chhattisgarh and Vidarbha.

Strong or gusty winds could affect some areas of Sikkim and Jharkhand.

Rain Alert for Madhya Pradesh and Chhattisgarh

Central India is also likely to remain under the influence of active monsoon conditions.

Both eastern and western parts of Madhya Pradesh could receive heavy rainfall, while Chhattisgarh may experience a combination of rain, thunderstorms and lightning.

Vidarbha is also expected to witness heavy showers at isolated locations.

During intense spells, commuters should be particularly careful on roads where visibility can fall quickly and waterlogging can develop.

Uttarakhand, Himachal and Jammu-Kashmir May Get More Rain

Rainfall activity is also expected across the Himalayan region, including Himachal Pradesh, Jammu and Kashmir, Ladakh and Uttarakhand.

Uttarakhand could additionally experience thunderstorms accompanied by lightning.

In hilly regions, prolonged or intense rainfall can increase the possibility of localised landslides, falling rocks and disruption on vulnerable roads. Travellers should therefore check local conditions before heading towards affected hill routes.

Heavy Rain Possible in East Rajasthan

Parts of East Rajasthan are also likely to experience heavy rainfall.

The weather could remain unsettled in neighbouring areas as monsoon systems continue to influence northern and central India.

Meanwhile, thunderstorms and lightning have been forecast for East Uttar Pradesh and West Uttar Pradesh, apart from Uttarakhand.

Residents should avoid taking shelter under isolated trees or standing in open areas when lightning activity is intense.

Northeast India Braces for Widespread Rain

The northeastern states are also expected to experience widespread rainfall.

Rain is forecast across Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura.

Thunderstorms accompanied by lightning could affect several of these states, particularly Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur and Mizoram.

Persistent rainfall in northeastern India can lead to localised flooding and landslide concerns, especially in hilly and low-lying areas.

Maharashtra, Gujarat and Goa Under Rain Watch

Western India is another region where the monsoon is expected to remain active.

Rainfall is likely over Marathwada, Saurashtra and Kutch, while heavier spells are expected across Konkan and Goa, Madhya Maharashtra and Gujarat.

Madhya Maharashtra, in particular, could receive very heavy rainfall at isolated locations.

Parts of Gujarat, Saurashtra and Kutch may additionally witness thunderstorms and lightning.

States and Regions Under Rain Alert on August 13

What Should People Do During Thunderstorms?

With lightning and thunderstorms expected across several states, basic precautions can reduce risk. People should move indoors when thunder is heard and avoid open fields, isolated trees, electricity poles and exposed elevated locations.

During very heavy rainfall, avoid driving through waterlogged roads or attempting to cross overflowing streams and underpasses. In hill states, travellers should also monitor local administration and traffic advisories before starting their journey.

Since weather conditions can change quickly during the monsoon, residents in affected states should follow the latest district-level forecasts and warnings issued by the IMD and local authorities.
