Gov. Rick Scott on Tuesday urged families to be prepared for severe weather that is expected to move through the Panhandle and north Florida overnight.
The governor directed state transportation workers to spray down state bridges and roads with a saline solution in anticipation of the storm.
More than 20 counties have or were planning to open cold weather shelters.
Schools in five districts have already announced they would be closed on Wednesday. The city of Jacksonville announced it was closing its offices out of "an abundance of caution."
State government offices were expected to be open.
