Overview

• IMD projects September rainfall at about 109% of the long-period average of 167.9 mm, with most regions likely to see normal to above-normal rain.
• Authorities are cautioned about landslides and flash floods in Uttarakhand and Himachal Pradesh, with possible disruption in south Haryana, Delhi and north Rajasthan, and heavy rain over the upper Mahanadi catchment in Chhattisgarh.
• Northwest India logged 265 mm in August, the highest for the month since 2001, driven by frequent western disturbances interacting with monsoon low-pressure systems.
• From June 1 to August 31, India received 743.1 mm of rain, about 6% above normal, alongside severe impacts including Punjab’s worst flooding in decades and repeated cloudbursts and landslides across Himalayan states.
• IMD expects continued rain into early September with a fresh Bay of Bengal low on September 2, has ruled out monsoon withdrawal in the first week, and reports localized extremes such as Marathwada flash floods and Ludhiana surpassing last year’s seasonal total.
