A monsoon low will lead to heavy rain and potential flooding across India into this weekend.
On the heels of heavy rain and flooding across a large swath of India last week, a monsoon low from the Bay of Bengal will cross India to bring a new round of flooding.
Showers and thunderstorms brought torrential rainfall to Odisha, Chhattisgarh, eastern Maharashtra and northern Andhra Pradesh through Wednesday.
The downpours have already resulted in numerous reports of flash flooding and at least four deaths across Odisha, according to the Times of India.
Rainfall has totaled over 300 mm (12 inches) in Jagdalpur this week with widespread reports of around 100 mm (4 inches).
The Nagavalli and the Kalyani rivers have risen at alarming rates inundating vast areas, causing extensive damage to bridges and snapping road and railway connectivity.
The rainstorm will track northwest across the country, reaching Gujarat by this weekend. At least nine people were killed in Gujarat from flooding last week. Additional downpours will quickly create a dangerous situation across the state.
Rainfall totals will average 100-200 mm (4-8 inches), with local amounts over 300 mm (12 inches) from northern Maharashtra and Madhya Pradesh to Gujarat later this week.
The heaviest downpours will shift into Madhya Pradesh and northern Maharashtra on Thursday and Friday before moving into Gujarat this weekend.
Tropical cyclones and monsoon lows are essential for bringing rainfall to India during the monsoon season, but they can also threaten widespread flooding and increase the risk for mudslides.
Farther north, New Delhi and the National Capital Region will have the threat for a daily shower or thunderstorm, but heavy rainfall is not expected to be widespread this week.

During the past several weeks, flooding in northeastern India has contributed to 90 deaths, according to the Times of India .
Assam was hit the hardest, with 69 lives lost in floods and landslides according to India.com.
Roughly 2 million people have been displaced, Assam Chief Minister Sarbananda Sonowal told Reuters.
The city of North Lakhimpur was inundated with more than 340 mm (13 inches) of rain last week. The Brahmaputra River and its tributaries significantly overflowed their banks but have since started to recede.
The heavy rainfall in Assam also flooded more than half of the Kaziranga National Park , which is home to the world’s largest one-horned rhinoceros population.
Heavy rainfall is not expected across Assam the next several days; however, localized downpours can still result in additional flooding. The threat for widespread downpours will return this weekend.
