Discussion

Low pressure is going to intensify significantly this weekend near the Southeast US coastline, induced by a frontal boundary zone that slides into the region, and energized by an upper-level trough that drops southeast across the Great Lakes. It appears likely that this strong coastal storm will then push far enough to the north to have an impact on the Mid-Atlantic region all the from late Saturday night into late Monday. The worst impact will be along coastal sections where rain will be heaviest, winds will be strongest, and the threat of coastal flooding/beach erosion will be high due to a prolonged period of onshore flow. In terms of some specifics for the NYC metro region, estimates are for east-to-northeast wind gusts of 50-60 mph along coastal sections, 30-50 mph inland...3+ inches of rain along coastal sections, and 1-3 inches inland.
