All clear concerning the risk of severe thunderstorms that passed through the area this morning and around midday. A wind advisory remains in effect for sustained winds 15 to 30 mph with gusts as high as 40 mph across most of metro New Orleans (south shores of Lakes Pontchartrain and Borgne) and southeast Louisiana coastal areas. Gale warnings remain in effect across the marine area for sustained winds near 30 knots and gusts around 40 knots and associated dangerous wave conditions.
Cold wind chill values in the upper teens and 20s are expected due to the strong winds and cold temperatures late tonight and early Sunday. A light to moderate freeze is expected Sunday night/early Monday with lows 26 to 32 across areas mainly north and west of Lake Pontchartrain into south Mississippi.
Late this afternoon is the beginning of the weather advisory through early Sunday morning for the winds and marine hazards. Late tonight and early Sunday morning for the cold wind chills, and late Sunday night and early Monday morning for the light to moderate freeze across much of the area.
Sustained winds through early Sunday morning could blow around lighter, unsecured objects and produce strong cross winds on elevated roads and bridges.
