NEW ORLEANS (WGNO) — If you live in Southeast Louisiana or along the Mississippi Coast, it’s important to stay weather aware Sunday.
The National Weather Service has issued a “Marginal Risk,” threat level 1 out of 5, for severe thunderstorms on St. Patrick’s Day, particularly areas along and south of the I-10/I-12 corridor.
The main timeframe for concern Sunday is late morning through the afternoon. Any strong or severe storms that develop have the potential to bring damaging wind gusts, isolated tornadoes, and large hail.
Additionally, there’s a “Slight Risk,” threat level 2 out of 4, for heavy rainfall which could result in localized flooding. Urban areas and places with poor drainage are especially vulnerable.
While the exact amounts and areas at risk depend on the system’s location and speed, the latest forecast models predict 1 to 3 inches of rain during the day, with some areas experiencing even higher amounts.
Given the current high soil moisture, runoff from the rainfall could exacerbate flooding issues. The National Weather Service is advising residents to clear drains and catch basins of any debris that could block water flow.
Be sure to have multiple ways to receive weather warnings and to know where your safe place is in case you need to take shelter.
