Most of south Louisiana will be under a flash flood watch from Sunday morning through Monday, according to the National Weather Service.

Weather predictions suggest between 3 to 5 inches of rain with higher amounts possible through Monday, with localized flooding might occur in urban and poor drainage areas.

A flash flood watch means that there are conditions that may develop into flash flooding.

The rain should ease drought conditions that have caused lawns to become brittle and prompted the fire marshal to issue a burn ban for the entire state.

More than a month has passed since Baton Rouge has had significant rain, and the rest of the state hasn’t fared much better. Almost 54 percent of the state is in extreme drought, but relief could be on the way this weekend and into next week.

“Right now, we are the drought hot spot east of the Rocky Mountains,” said Barry Keim, the state climatologist.

In Baton Rouge, there has been only 0.14 inches of rain over the last 30 days, which is about 4 percent of normal. The Lafayette area is worse, with only 0.13 inches of rain, or about 3 percent of normal. New Orleans has fared a bit better, with 1.2 inches of rain, or 36 percent of normal.
