STORM SURGE: A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 4 to 6 feet above normal tide levels near where the center of Maria moves across the Leeward Islands. RAINFALL: Maria is expected to produce total rain accumulations of 6 to 12 inches with isolated maximum amounts of 20 inches across the Leeward Islands, including Puerto Rico and the U.S. and British Virgin Islands through Wednesday night. Maria is also expected to produce total rain accumulations of 2 to 4 inches for the northern and central Windward Islands. In all the above areas, these rainfall amounts could cause life-threatening flash floods and mudslides. SURF: Swells generated by Maria are beginning to affect the Lesser Antilles.
