Coastal Flood Advisoryuntil Wed 10 PM

Evening high tide brings peak flooding through 10 PM

This evening's high tide is the peak of the week's coastal flooding in Rehoboth Beach, with minor flooding on the most vulnerable coastal and bayside roads and moderate flooding possible in some back bays; the advisory runs until 10 PM. Waves of 10 feet or more just offshore will keep chewing at the beaches around high tide, and coastal gusts of 30 to 40 mph linger into the evening.
