Heavy rainfall and strong to severe thunderstorms are possible on Sunday as an area of low pressure moves into Southwest Louisiana.

The National Weather Service’s Lake Charles office said the excessive rainfall is expected much of the day Sunday across much of the region and lower southeast Texas.

Rainfall totals across the area are expected to be between 1 and 3 inches, but locally higher amounts will be possible, and this could result in minor flooding of urban and poor drainage areas, the agency said.

The area is at a marginal risk for isolated hail and damaging winds, along with a few isolated weak tornadoes.
