Tropical Storm Isaias, located off the north Florida coast, will continue to move to the north, turning north-northeast this afternoon along the southeast coast. Isaias will continue moving northeast tonight over Eastern North Carolina. Isaias will slowly weaken as it accelerates northeast on Tuesday, likely moving over our area Tuesday afternoon and evening. There is still some timing and intensity uncertainty with this storm. However, confidence continues to increase with respect to the magnitude of local hazards and impacts.
The main threats with this system involve heavy rainfall, strong winds, minor to moderate coastal flooding, along with high surf and dangerous rip currents.Locally heavy rain is expected with a widespread 2 to 4 inches, with localized amounts up to 6 inches possible. The heaviest rain is most likely to occur across New York City, Northeast New Jersey and the Lower Hudson Valley early Tuesday morning through Tuesday evening, and eastern sections Tuesday afternoon into Tuesday night.
The effects from Tropical Storm Isaias are expected to diminish quickly from southwest to northeast across the area Tuesday night.
