LEE COUNTY, Fla. - For as cold as it feels in Southwest Florida, it's worse in other parts of the state.  The National Weather Service predicts the potential for record-setting temperatures again for many areas tonight.

Tallahassee was forecast to dip into the low 20s.  Jacksonville, Orlando and Tampa also face another night below the freezing mark.

Near Ft. Lauderdale, manatees were found seeking the warmer waters of Port Everglades.  In Orlando, a reporter with WKMG-TV captured a photo of a palm tree coated in ice.  In Miami, the tourist on South Beach are bundling up.

Helicopters were expected to hover over fields near Tampa again Tuesday night.  The choppers fly low, forcing the rising warm air back to the ground in an effort to keep crops insulated against the cold.

Several ships attempting to enter Tampa Bay, including a Carnival cruise-liner, were delayed one day by high winds and rough seas.  Officials say it would have been too dangerous to navigate under the Sunshine Skyway bridge in Monday morning's conditions.  Carnival passengers say the ship rocked back and forth in the wind and waves.

The December cold snap is even being felt as far south as Key West, where Tuesday's high temperatures failed to climb out of the 50s, staying more than 20 degrees below the norm.
