The retreating monsoon continues to influence weather conditions across India, bringing the possibility of rain, thunderstorms, lightning and strong winds to several regions. According to the forecast cited in the source, the India Meteorological Department has issued weather updates covering as many as 18 states and Union Territories, including Rajasthan, Delhi-NCR, Uttar Pradesh, Bihar, West Bengal, Madhya Pradesh and Chhattisgarh.

Weather conditions will not be uniform across every district. Some places may receive intense spells of rain, while others could experience only cloudy skies or isolated showers. Residents should therefore check the latest district-level forecast and warning before travelling.

Delhi-NCR may receive isolated light rain

Rainfall activity has weakened across Delhi and the National Capital Region, but partly cloudy conditions may offer some relief from strong daytime sunshine.

The maximum temperature on September 19 is expected to remain near 35 degrees Celsius, while the minimum may settle around 23 degrees Celsius. Light rain is possible in a few locations, although widespread heavy rainfall has not been indicated in the supplied forecast.

Conditions are expected to become clearer on September 21, 22 and 23. However, residents should continue following short-term weather bulletins because thunderstorms and lightning can develop quickly.

Rajasthan braces for more rain

A fresh weather system has affected Rajasthan, bringing heavy to very heavy rainfall to parts of the state. Rain is expected to continue in several areas on September 19.

Meanwhile, conditions may become favourable for the southwest monsoon to withdraw from some parts of western Rajasthan. This means rainfall activity could gradually decrease in the western region even as eastern and southeastern districts remain vulnerable to showers.

Isolated light to moderate rain is possible over eastern and southeastern Rajasthan on September 20. Weather conditions are likely to become mainly dry across most of the state from September 21.

Rainfall intensity can vary considerably between neighbouring districts. Travellers should review local warnings, road conditions and waterlogging reports before starting their journey.

Rain and thunderstorms forecast in Uttar Pradesh

Weather conditions are gradually changing across Uttar Pradesh. Rain has weakened in several districts, while daytime temperatures have begun to increase. Despite this decline in overall activity, thunderstorms and lightning remain possible in some areas.

Eastern Uttar Pradesh may experience rain, thunderstorms and lightning on September 19 and 20. Parts of western Uttar Pradesh could witness similar conditions on September 19.

People in areas covered by a thunderstorm warning should avoid open fields, isolated trees, rooftops and metal structures when lightning begins. Farmers and outdoor workers should move to a secure building as soon as they hear thunder.

Bihar may see rain until September 24

Unsettled weather could continue across Bihar for several more days. Some parts of the state may receive rain accompanied by thunderstorms and lightning on September 19.

The source report states that heavy rainfall was recorded in certain areas on September 18. Rainfall activity could continue in multiple districts until September 24, although its intensity and distribution may change from day to day.

Residents should follow district-specific alerts because a state-level forecast does not mean every location will receive the same amount of rain. People living in low-lying areas should also remain alert to waterlogging after an intense spell.

West Bengal faces rain and gusty winds

Several parts of West Bengal, including Kolkata, have been experiencing rain. Additional rainfall, thunderstorms, lightning and gusty winds are forecast in parts of the state.

South Bengal may witness scattered rain along with thunderstorms. People should remain cautious during sudden changes in weather, particularly when strong winds or lightning are reported.

Rain and thunderstorms are also expected across several districts of north Bengal. Isolated heavy rainfall may occur in:

• Darjeeling
• Kalimpong
• Jalpaiguri

Those travelling through hilly areas should monitor local advisories because heavy rain can affect road visibility and increase the risk of landslides or falling debris.

Low-pressure area may develop over Andaman Sea

A low-pressure area is expected to form over the north Andaman Sea around September 19. According to the cited forecast, the system may move towards the coasts of southern Odisha and northern Andhra Pradesh during the following three to four days.

Its formation and movement could influence rainfall over parts of eastern and central India. The system’s exact path and intensity will become clearer through subsequent meteorological updates, so residents in potentially affected coastal and adjoining regions should monitor official bulletins.

Madhya Pradesh and Chhattisgarh under rain watch

Rainfall is also forecast in Madhya Pradesh and Chhattisgarh, particularly over their eastern regions. Eastern Madhya Pradesh may receive rain in some places, with thunderstorms and lightning possible across several areas.

Similar unstable conditions could affect parts of Chhattisgarh. Since thunderstorm activity can be highly localised, people should take precautions even if the weather initially appears calm.

Safety precautions during thunderstorms and heavy rain

People living in areas covered by rain or lightning alerts should keep mobile phones charged and follow official weather warnings. Unnecessary travel should be postponed during intense rainfall, especially where roads are flooded or visibility is poor.

Avoid standing under trees or near electricity poles during thunderstorms. Drivers should slow down, maintain a safe distance from other vehicles and never attempt to cross a heavily flooded road without knowing its depth.

This forecast is based on the information supplied for September 19, 2026. Weather conditions can change quickly, so readers should verify the latest local forecast and warning issued by the IMD before making travel or outdoor plans.
