Tropical Storm Arthur continued to slowly drift towards the northwest as its sustained winds increased to 50 miles per hour.
At 11 p.m., the center of the storm was located about 90 miles east-southeast of Cape Canaveral, Florida or 100 miles north-northwest of Freeport, Grand Bahama Island.
No watches were in effect for South Florida, but a tropical storm watch was in effect for the east coast of Florida from Fort Pierce to Flagler Beach. Tropical storm conditions are possible in the watch area within the next 24 to 36 hours.
The National Hurricane Center said areas north of the watch area through southeastern Virginia should monitor the storm because tropical storm and hurricane watches may be issued in the next few days.
The NHC said the center of the storm is expected to remain just offshore and move along the east-coast for the next day or so. The system should pass east of northeastern Florida on Wednesday and Wednesday night.
Arthur may become a hurricane by Thursday.
