Winter Storm Warning Issued for Southeast Louisiana

NEW ORLEANS, La. — A Winter Storm Warning is in effect for much of southeast Louisiana as an Arctic cold front threatens to bring snow, sleet, and freezing rain to the region. The warning, issued Monday night through Tuesday, could result in hazardous travel conditions and significant snowfall accumulations, particularly north of Interstate 10.

The National Weather Service predicts snow accumulations of 2 to 4 inches in the River Parishes and New Orleans metro area, with higher totals of 3 to 6 inches expected on the North Shore. Coastal areas, including Plaquemines Parish, may see a mix of sleet, freezing rain, and up to an inch of snow. Temperatures are expected to plummet into the 20s and 30s, with wind chills making it feel even colder.

“This is a developing Gulf low interacting with Arctic air, which is unusual for our region,” said a WDSU meteorologist. “We’re looking at a mix of precipitation types, including sleet, freezing rain, and snow, which could create dangerous conditions on roads.”

Residents are urged to prepare for the storm by stocking up on essentials, protecting pipes from freezing, and avoiding unnecessary travel. A Cold Weather Advisory is also in effect for Sunday and Monday nights, with wind chills expected to dip into the teens and low 20s.

In New Orleans, the storm could begin with sleet early Tuesday before transitioning to snow. The heaviest snowfall is expected between noon and 4 p.m., tapering off by Tuesday night. Similar conditions are forecast for the River Parishes and Bayou Parishes, where a mix of snow and sleet is likely.

“This is a workhorse forecast,” the meteorologist added. “We’re seeing consistent predictions from both U.S. and European models, which gives us confidence in the timing and intensity of this event.”

Authorities are warning residents to stay off the roads if possible, as icy conditions could make travel treacherous. The storm coincides with the Martin Luther King Jr. holiday, potentially disrupting plans for many across the region.

As the storm moves out, temperatures will remain bitterly cold through Wednesday, with hard freezes expected in northern areas. Residents are advised to protect pets, plants, and pipes, and to stay tuned for updates as the forecast evolves.
