Prior to the arrival of the heavy rain and high winds from Hurricane Irene, smoke from the Great Dismal Swamp fire continues to be problematic. There have been some very low visibilities reported at several National Weather Service observing locations this morning. As a result, Code Purple conditions are now likely in Suffolk for today. Code Red to occasionally Code Purple conditions are likely in Southampton and Isle of Wight counties. Code Orange to occasionally Code Red conditions are likely in Sussex and Surrey counties.
