Individual waves may be more than twice the significant wave height. .SYNOPSIS...Fresh to strong NE to E winds and rough seas are expected north of 27N through Sun morning as a tight pressure gradient persists between high pressure to the N and a stationary front extending from the Straits of Florida to 1009 mb low pressure near 27.5N92W.
