GOHSEP SITUATION REPORT

27 January 2014

As of 1330 Hours

STATE EOC ACTIVATION LEVEL: Modified Level III

WebEOC Incident Name: 007-14 Winter Weather - Statewide – 28-30, January 2014

 

SITUATION: GOHSEP is currently monitoring an impending winter weather situation slated to impact the state. A cold front is currently pushing through the state, bringing with it freezing temperatures from an arctic air mass.  Concurrently, an upper level disturbance tracking across the western Gulf of Mexico will begin to move moisture into the southern half of the state late this evening and into the overnight hours. The combination of frigid temperatures and moisture will set up for a potential significant winter weather event. This is a very fluid situation and is being monitored closely.

 

The breakdown of impacts are below:

 

NWS Slidell:

-        A  Winter Storm Watch is in effect for the entire forecast area. This is likely to be upgraded to a Winter Storm Warning later today.

-        All forms of precipitation will be possible Tuesday and Tuesday night.

-        Ice accumulations will be possible before it transitions over to snow. Possible accumulations of snow could reach up to 4 inches in some areas, while possible accumulations of ice could reach up to .25 inches.

-        Heaviest ice accumulations at this time are expected to occur along and south of the I-10/12 corridor including Metro New Orleans.

-        Heaviest snow accumulations at this time are expected to occur north of the I-10/12 corridor in the northern reaches of the north shore Parishes.

-        A Hard Freeze is expected as duration of below freezing temperatures can be 48 to 60 hours long.

-        Estimated Timing and Duration:

o   Baton Rouge: below freezing very early Tuesday morning; onset of freezing rain by sunrise Tuesday, onset of sleet by early afternoon with some snow mixing in. Transitioning to all snow before ending very late Tuesday night.  

o   New Orleans: below freezing shortly after sunrise Tuesday; onset of freezing rain by mid-late morning, transitioning to sleet by late afternoon with some snow possibly mixing in before ending very early Wednesday morning.
