Maximum sustained winds are 85 kt with gusts to 105 kt, and the minimum central pressure is 974 mb. Strong winds and rough seas associated with Nigel will continue to affect the forecast waters through Wed. A stationary front extending from near 31N70W to South Florida will change little through Thu. The frontal boundary should begin to slowly lift northward on Fri as low pressure develops along it to the east of northern Florida where gale conditions and rough seas are possible Thu night into Fri. This non-tropical area of low pressure could acquire some subtropical characteristics this weekend while it moves generally northward. Regardless of subtropical development, this low is likely to bring gusty winds, heavy rain, and high surf conditions to portions of the coastal Carolinas into the coastal Mid- Atlantic states late this week into this weekend.
