The Indian Meterological Department (IMD) had issued a monsoon alert, forecasting rain, thunderstorms, and strong winds in 18 states. Delhi, gearing up for the BRICS Summit on September 12  and 13, is likely to witness rain on both these days.

The weather is likely to remain bad in many states, including Delhi, Uttar Pradesh, Bihar, Haryana, Punjab, Himachal Pradesh, Jharkhand, Madhya Pradesh, Maharashtra, Rajasthan, Gujarat, Jammu and Kashmir, Assam, Chhattisgarh and Arunachal Pradesh.

The IMD has attributed this to the low-pressure area persisting in the Bay of Bengal. "Tomorrow, the westerly winds are likely to turn easterly. The low-pressure area, currently over southern Odisha, is expected to move towards central Madhya Pradesh, bringing rainfall activity over the region," said Mahesh Palawat of Skymet.

He also issued an alert for Delhi, stating light rain is expected in Delhi from the evening hours on September 11. “Light to moderate rainfall, with isolated moderate spells, is likely on September 12 and 13. This could be one of the last spells of the monsoon over Delhi this year," he said.

Low-pressure area

A heavy rain alert has been issued in Madhya Pradesh, and a warning of rain and thunderstorms has also been issued in Uttar Pradesh. The weather is also set to change in Rajasthan.

A new phase of rain is likely to start in Madhya Pradesh due to the low-pressure area formed in the Bay of Bengal, active monsoon trough and cyclonic circulation formed in the western part. Its effect will be more in eastern Madhya Pradesh on Friday, whereas from Saturday, rain may increase in the western part as well.

The weather in Rajasthan is set to change again in two days. A new round of rain is about to begin in various parts of the state. Currently, dry westerly winds are blowing across most of the state, causing temperatures to rise. However, the influence of a new weather system forming in the Bay of Bengal will likely alter both temperature and rainfall conditions in the coming days.
