Maximum sustained winds are 85 kt with gusts to 105 kt, and the minimum central pressure is 971 mb. Nigel is forecast to accelerate northeastward later today as it pulls farther away from the area. Strong winds and seas 12 ft or greater north over the northwest part of the area will lift north of 31N later this morning. A stationary front extending from near 31N70W to east- central 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 by this weekend while it moves generally northward.
