GOHSEP SITUATION REPORT

27 January 2014

As of 1800 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.
