Developing monsoon low to renew flood threat along western India


The wet season has been taking a devastating toll in parts of the Bay of Bengal region since arriving late in May and throughout the month of June. More rain is on the way for areas that have already been inundated with floodwaters.

On Friday, the death toll rose to 34 in the state of Assam, located in northeastern India, as rounds of heavy rain continued to exacerbate flooding across the area. Over 1.6 million people in 22 different districts have been impacted by the flooding across the state, according to The New Indian Express.

At least 20 deaths have been blamed on lightning in the state of Bihar after strong thunderstorms developed on Thursday.

An additional 21 people were killed by lighting strikes in Bihar on Saturday. Lightning is being blamed for 17 deaths in Uttar Pradesh to start the weekend.

On Saturday morning, local time, a landslide in the Bajhang district in Nepal has killed at least six people and one other is still missing. 400 people have been displaced by the landslide and 45 homes are still at risk of being swept away, according to a report from The Kathmandu Post.

Monsoon rainfall has also led to severe flooding in Bangladesh, stranding hundreds of thousands of people, and deadly landslides in Myanmar.

Occasional showers and thunderstorms are forecast to continue across much of India throughout the weekend with the monsoon in full swing across the region.

Any thunderstorms that develop can produce localized flooding, gusty winds and frequent lightning strikes.

The area under the highest risk of flooding will continue to be northeastern regions as flooding downpours will be in the forecast for the eastern Himalayan Mountains as well as where the water runs downstream.

More rounds of heavy rainfall in an area with saturated ground will also greatly increase the risk of mudslides in this area.

Moisture from the Arabian Sea and a developing monsoon low will help to fuel heavier downpours along the coastal areas from southern Gujarat to Kerala in western India into the beginning of next week as it shifts north.

The risk of flooding will be high along the western coast of India with rainfall totals expected to climb as high as 200-300 mm (8-12 inches) by the middle of next week.

As the monsoon low continues to meander to the north and west it is forecast to bring more widespread showers and thunderstorms to northwestern India, including the capital region, by the middle of the week.

The southwest monsoon season typically lasts throughout the summer months before it begins to gradually recede from northwest to southeast across India during the months of September and October.
