Weather conditions are expected to remain unsettled across large parts of India on September 18, 2026, with rain, thunderstorms and strong winds forecast in several regions. According to the weather alert cited in the report, as many as 21 states and Union Territories could experience varying spells of rain and stormy conditions during the day.

The forecast covers several parts of north, east, west, central and northeast India. Uttar Pradesh, Bihar, Rajasthan and Delhi are among the regions where rain and thunderstorms have been predicted. Wind speeds could also increase sharply in isolated locations, with gusts reportedly capable of reaching around 85 kmph in some areas.

Since weather conditions can change quickly, residents in affected regions should follow the latest local forecasts and warnings, particularly during thunderstorms, lightning and strong winds.

Rain and Thunderstorm Alert Across Several States

The September 18 forecast mentioned in the report covers Uttar Pradesh, Bihar, Delhi, Rajasthan, Haryana, Himachal Pradesh, Uttarakhand and Punjab.

Jammu and Kashmir and Ladakh are also included, along with Jharkhand, West Bengal and Odisha in eastern India.

Gujarat, Maharashtra, Madhya Pradesh and Chhattisgarh may also witness unsettled weather. Assam and Meghalaya in the Northeast and Andhra Pradesh in southern India are among the other regions mentioned in the alert.

However, the intensity and timing of rainfall may differ considerably from one district to another. An alert for a state does not necessarily mean every location will receive heavy rainfall.

Strong Winds May Accompany Thunderstorms

Apart from rainfall, strong winds are another important part of the forecast.

The report suggests that wind speeds could reach up to 85 kmph in some locations. Uttarakhand, Andhra Pradesh, West Bengal and Chhattisgarh are among the areas where winds in the range of around 70-80 kmph have been indicated.

Strong gusts associated with thunderstorms can potentially affect trees, weak structures, outdoor objects and standing crops. People should therefore pay attention to district-level warnings if severe weather develops in their area.

What Is Driving the Change in Weather?

Several atmospheric systems are cited as contributing to the unsettled conditions.

A cyclonic circulation is reported over northeast Assam and adjoining areas in the lower tropospheric levels. Another circulation is said to be influencing western Uttar Pradesh and neighbouring regions.

Moisture-bearing winds from the Bay of Bengal may also support rainfall and thunderstorm activity across parts of the country.

The report additionally mentions the possibility of lightning and hail in some eastern regions. Since thunderstorms and lightning can develop locally, residents should rely on updated short-range warnings for their specific location.

Delhi Weather Forecast for September 18

Delhi could experience rain and thunderstorms on September 18.

According to the forecast cited in the report, winds may reach around 30-35 kmph. The maximum temperature is expected to be around 33°C, while the minimum could remain near 24°C.

People travelling across Delhi-NCR should remain prepared for temporary disruption if a strong spell of rain or thunderstorm activity develops.

During lightning or strong winds, it is safer to avoid unnecessary exposure in open areas and stay away from vulnerable trees, poles and unsecured outdoor structures.

Uttar Pradesh Weather: Several Districts Under Watch

Rain and thunderstorm conditions are also forecast across multiple districts of Uttar Pradesh, with the report referring to a yellow alert for several locations.

The districts mentioned include Meerut, Ghaziabad, Muzaffarnagar, Moradabad, Gautam Buddha Nagar, Saharanpur, Hapur, Lakhimpur Kheri, Aligarh, Mathura and Agra.

Unsettled weather has also been indicated for Etawah, Jhansi, Lalitpur, Rae Bareli, Hardoi, Unnao, Hamirpur, Amethi, Sultanpur, Azamgarh, Ayodhya, Prayagraj, Deoria, Mainpuri and Gorakhpur.

For Lucknow, the maximum temperature is expected to be around 33°C, while the minimum temperature could remain close to 26°C.

Residents should keep track of local alerts because rainfall and thunderstorm intensity can vary significantly even between neighbouring districts.

Rajasthan Rain Forecast: Jaipur Among Areas to Watch

Several parts of Rajasthan could receive moderate to heavy rainfall, according to the forecast cited for September 18. Strong winds are also possible in some areas, including Jaipur.

Districts mentioned in the forecast include Jaipur, Udaipur, Baran, Churu, Sawai Madhopur, Bundi, Kota, Dausa, Barmer, Bhilwara, Bharatpur, Jaisalmer, Alwar and Jalore.

For Jaipur, the maximum temperature has been forecast at around 29°C, while the minimum could settle near 22°C. Winds may reach approximately 50 kmph during periods of stronger weather activity.

Rainfall distribution across Rajasthan is unlikely to be uniform, so conditions in one district may differ substantially from another.

Keep Checking Local Weather Warnings

With rain, thunderstorms, lightning and strong winds forecast across several regions on September 18, people should keep an eye on updated local weather advisories throughout the day.

Forecasts can change as weather systems evolve. District-level warnings from the India Meteorological Department and instructions issued by local authorities should therefore take priority, especially when travelling or working outdoors.

Those living in areas affected by thunderstorms should take particular care during lightning and strong winds and avoid assuming that a statewide alert means identical weather conditions everywhere.
