No Thomas County roads or state routes in the county are closed. U.S. 19 North also remains open.
It is not anticipated that any roads will close, said Capt. Steven Jones, Thomas County Sheriff's Office public information officer.
Jones said Thomas County residents should go home early today, if possible, and not be on roads after dark.
The temperature will not be as high as thought today and lower than anticipated tonight.
"Things that were frozen will refreeze," said Chris Jones, Thomas County emergency management agency director.
