A monsoon low that tracked across central India last week is now moving northward as heavy rain falls in northwestern India.
Since Friday, heavy rain pounded the city of Surat, totaling more than 330 mm (13 inches) of rain, with lighter rain continuing into Sunday.
Through the first half of this week, the core of the heaviest rain will move to the north, spreading into Kashmir and Himachal Pradesh Tuesday and Wednesday.
The most widespread areas of rain will stretch along the Pakistan and India border, stretching east toward New Delhi. Rainfall amounts of 1-3 inches (25-75 mm) will be common across this area with a few areas getting in excess of 3 inches (75 mm). Lahore will be one city at risk for heavy rainfall.
"The moisture will be pulled as far north as Kashmir and Nepal," AccuWeather Senior Meteorologist Jason Nicholls said. This is where downpours are expected through Wednesday as moisture is pushed into the Himalayan Mountains.
Moisture streaming into the mountains will cause heavy rain from Kashmir to Himachal Pradesh with upwards of 6 inches (150 mm) possible. Rainfall of this magnitude will be capable of producing life-threatening flash flooding and mudslides.
While dangerous flooding is possible through Wednesday, the rain will also be beneficial for areas that could be receiving one of their last significant precipitation events prior to the start of the dry season which will last until the monsoon rains return next summer.
Following this surge of downpours, dry weather is expected to settle into western India for the rest of this week and continue into next week.
Meanwhile, another surge of monsoonal moisture from the Bay of Bengal will aim for eastern coast of India, bringing a period of drenching showers and thunderstorms across northeastern India early this week. Localized flash flooding is expected across northeastern India and Bangladesh.
