A wind advisory is in effect until 8 a.m. and it's expected to remain cold today, according to forecasters with the National Weather Service.
The boat scheduled to depart to Fort Sumter at 11 .m. has been cancelled due to high winds in the harbor. The 1:30 and 2:30 p.m. boats are expected to run on schedule unless conditions change, according to park officials.
Winter storms in the northeast are also affecting travel out and into Charleston.
In the Lowcountry, high temperatures today are only expected to reach the lower 40s with 15 to 25 mph winds and gusts up to 35 mph.
Tonight, temperatures are expected to dip to the upper 20s. Tomorrow night, there is a 20 percent chance of rain and temperatures are not expected to be as cold, with lows in the mid 40s.

Winter storms along the east coast today are affecting travel as nearly two feet of snow dropped just north of Boston, shutting down major highways in New York and Pennsylvania and forcing U.S. airlines to cancel thousands of flights nationwide.
John F. Kennedy Airport in New York City shut down at around 6: 45 a.m. but reopened at 10:15 a.m., according to its website. About ten flights departing from Charleston International Airport had been canceled or delayed since this morning, departing to Charlotte, Washington D.C., Newark and Chicago, according to airport officials.
Nine flights arriving to Charleston were also canceled, coming from Washington D.C., Chicago, New York, Newark and Philadelphia.
Charlene Gunnells, spokesperson for the Charleston County Aviation Authority, said she didn't know if there would be more cancellations later today. "There is no way for us to predict cancellations or delays. The decision to cancel or delay a flight is determined by the airlines and the airports in the areas experiencing bad weather," she said.
Gunnells said passengers should check with their airline for delays or cancellations before heading to the airport.
