Irene is an extremely dangerous storm for an area that has no experience with hurricanes, and I strongly urge you to evacuate from the coast if an evacuation is ordered by local officials. My area of greatest concern is the coast from Ocean City, Maryland, to Atlantic City, New Jersey. It is possible that this stretch of coast will receive a direct hit from a slow-moving Category 2 hurricane hitting during the highest tide of the month, bringing a 10 - 15 foot storm surge.
I’m personally a bit more concerned with areas slight to the south of Ocean City - like Chincoteague.
Jeff Masters really spells it out in his analysis. Particularly disturbing info about the highest tides of the year occurring during the same time.
