Subtropical Storm Josephine poses risks to coastal communities along the East Coast. The primary hazards include wind gusts of up to 40 mph, which may cause minor structural damage and power outages. Coastal flooding, with water levels rising up to 4 feet above normal, threatens low-lying areas and infrastructure near the shore. Dangerous rip currents are also expected, creating hazardous conditions for swimmers and surfers. Residents in flood-prone areas should prepare for potential evacuations, while beachgoers are urged to avoid entering the water during this period.
