The primary weather effects/hazards on the Southeast U.S. Coast remains heavy rain but adds a long duration strong easterly wind flow likely to raise havoc on coastal beaches with extensive erosion and inland flowing ocean water through river inlets flooding areas well inland. The onshore wind flow/accelerating water rise problem lasts well beyond the immediate storm as strong high pressure over the northeast maintains strong east wind through next week.

ECMWF forecasts heavy rain effects from Imelda early next week followed by a second event in the 11-15-day period. Each event combines for widespread flooding risk in the 15-day forecast.
