Winter Storm Warning in effect from 6:00 a.m. Tuesday to 6:00 a.m. Wednesday.

A strong cold front is moving through southeast Louisiana today ad is situated south of Lake Pontchartrain. A disturbance will move across the northern Gulf of Mexico on Tuesday and spread precipitation back into the area. With a very cold air mass already in place, precipitation is likely to fall as freezing rain...sleet or snow across most or all of the area. The potential exists for hazardous travel conditions from icing due to freezing rain as well as significant problems with tree limbs and power lines falling.

  • Timing: A wintry mix of precipitation could begin as early as daybreak tuesday morning, with the heaviest precipitation expected from midday Tuesday into Tuesday night.
  • Impacts: Precipitation will begin in the form of freezing rain across the entire area. Precipitation will slowly transition to sleet and snow generally north of the Interstate-10 corridor during the afternoon and evening. Ice accumulations of one quarter of an inch can be expected in all locations with accumulations possibly nearing one half inch south of Lake Pontchartrain and in the metropolitan New Orleans area. Snow amounts of one to three inches with locally higher amounts are possible especially in southwest Mississippi and the adjacent Louisiana parishes. Elsewhere in the warned area, snow amounts of near to less than one inch are expected. In addition, a hard freeze is likely on Wednesday morning across the entire area and wind chill values in the single digits are possible on Tuesday night and early Wednesday morning.
  • Main impact: Driving conditions will become especially hazardous beginning by daybreak tomorrow morning through mid-morning. Hazardous conditions will persist throughout the day on Tuesday and Tuesday night. Since temperatures will not rise above freezing for any significant period of time, hazardous driving conditions are likely to persist into Wednesday. In addition, ice accumulations of a quarter of an inch has the potential to cause significant problems with power lines and tree limbs becoming too heavy to maintain their integrity.

Precautionary/preparedness actions...

A winter storm warning means significant amounts of snow, sleet, and ice are expected or occurring. Strong winds are also possible. This will make travel very hazardous or impossible.
