Baton Rouge, LA – Freezing temperatures, ice covered bridges and widespread power outages can create dangerous conditions across Louisiana, even during winters with little snowfall. As winter weather awareness efforts continue Tuesday, October 27, residents are being reminded that freezing rain and winter flooding can threaten travel, homes and communities.
According to the National Weather Service NWS , freezing rain occurs when liquid precipitation freezes on contact with surfaces at or below freezing. Ice accumulation can make roads hazardous, damage trees and power lines, and disrupt electrical service.
How Dangerous Can Louisiana Ice Storms Become? Even a thin coating of ice can make bridges, overpasses and untreated roads extremely slippery. Accumulations approaching half an inch can cause substantial tree damage and widespread power outages.
Louisiana experienced significant winter weather in February 2021, when prolonged freezing temperatures and icy conditions disrupted travel and utilities.
In January 2025, a rare Gulf Coast winter storm brought substantial snowfall to portions of southern Louisiana, demonstrating that dangerous winter conditions can reach even coastal communities.
Drivers traveling Interstate 10, Interstate 20, Interstate 49 and Interstate 55 should exercise caution when freezing precipitation is forecast.
Ice Jams and Winter Flooding Risks River ice jams develop when accumulated ice restricts water flow, potentially causing flooding upstream.
Although significant river ice jams are exceptionally rare in Louisiana, prolonged freezing temperatures can create localized ice concerns along smaller waterways.
Heavy winter rainfall, saturated ground and rising rivers present more common flooding threats.
Communities near the Mississippi, Red, Ouachita and Atchafalaya river systems should monitor official river forecasts during periods of heavy rainfall.
How Louisiana Residents Can Prepare Before severe winter weather arrives, residents should take several precautions:
Protect exposed pipes and bring pets indoors during freezes. Keep flashlights, batteries, blankets and emergency supplies accessible. Charge phones and prepare for possible power outages. Avoid unnecessary driving on icy bridges and overpasses. Never operate generators or outdoor grills indoors. Stay away from downed power lines and flooded roads. Residents can monitor official forecasts through the NWS New Orleans/Baton Rouge office , NWS Shreveport office and NWS Lake Charles office .
Winter weather awareness efforts continue through Saturday, October 31 , emphasizing preparation before freezing temperatures, icy roads and winter flooding threaten Louisiana communities.
