A ***COLD WEATHER ADVISORY*** remains in effect until 9am Tuesday and again Tuesday night across southeast Louisiana and southern Mississippi. Very cold wind chills, as low as 20 degrees, could lead to frostbite or hypothermia if proper clothing is not worn. While the air temperatures should not be low enough to cause infrastructure issues for most of the Metro Area, those living north of the I-12 corridor may consider wrapping exposed, exterior pipes out of an abundance of caution.
