Heavy rain is expected to stick around south Louisiana for much of the weekend, prompting the National Weather Service to issue a flash flood warning for much of the Baton Rouge area through Sunday night.
In anticipation of the rain, the Downtown Business Association cancelled Friday’s Live After Five outdoor concert in downtown Baton Rouge.
In addition, the King’s Kids Club free movie night set for Friday evening at the Dr. Martin Luther King Jr. Community Center,was cancelled because of the weather, according to MLK Community Center Outreach Worker, Gabrielle Brown-Morgan.
The rainy weather is the result of a slow moving cold front due to stall over Louisiana this weekend at the same time a low pressure system from the west moves into the area bringing with it tropical moisture.
Forecasters expect rain levels to reach three to five inches with the possibility that some areas in south Louisiana could get more than eight inches through Sunday evening.
The heaviest rains Saturday will be in southwest Mississippi and the Baton Rouge area with an expected two to three inches for most areas, although some could see as much as five inches of rain by Saturday evening. On Sunday, the worst of the rain will move south and be located in areas like New Orleans and Houma.
Rainfall will continue into the early week, but the heaviest rainfall should be over by then, according to the National Weather Service.
The risk for flash floods will be greatest on Sunday because soils will already be saturated with rainfall leaving the new rainfall to run off into streets or waterways. However, since river levels across the area are running low, there is the ability to absorb some of the excess water and no rivers are forecast to flood, according to the National Weather Service.
Tides will be six inches to a foot above normal in Lake Pontchartrain and surrounding areas, which affects how much water can flow out of river systems, but the impact should be minor because the river levels are so low.
The additional rain could help with the increasing drought conditions that have been creeping over Louisiana in the past several weeks although it will make for a soggy weekend for football watching and tailgating.
According to the U.S. Drought Monitor, Louisiana went from having no drought conditions in 22 percent of the state last week to only a little over 1 percent of the state showing no drought conditions in this week’s report.
