Hurricane Maria headed for Virgin Islands & Puerto Rico
Tuesday, September 19, 2017, Caribbean Sea
At 500am AST (0900 UTC), the center of Hurricane Maria was near latitude 16.0 North, longitude 62.3 West… …moving toward the west-northwest near 9mph (15 km/h), and this general motion is expected to continue through Wednesday.

On the forecast track, the eye of Maria will move over the northeastern Caribbean Sea today, and approach the Virgin Islands and Puerto Rico tonight and Wednesday.

Maximum sustained winds are near 155 mph (250 km/h) with higher gusts. Maria is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely during the next day or two, but Maria is forecast to remain an extremely dangerous category 4 or 5 hurricane while it approaches the Virgin Islands and Puerto Rico.

Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205km).

Hurricane conditions will continue to spread throughout portions of the hurricane warning area in the Leeward Islands this morning. Hurricane conditions should spread through the remainder of the Hurricane Warning area later today and Wednesday.  Hurricane conditions are possible within the Hurricane Watch area in the Dominican Republic late Wednesday, with tropical storm conditions possible by early Wednesday. Tropical storm conditions are possible in the Tropical Storm Watch area in St. Vincent and the Grenadines this morning, and are possible in the Tropical Storm Watch area in the Dominican Republic on Wednesday

…A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 7-11 feet above normal tide levels in the hurricane warning area near where the center of Maria moves across the Leeward Islands and the British Virgin Islands.

The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline…

…The deepest water will occur along the immediate coast near and to the north and east of the landfall location, where the surge will be accompanied by large and destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances…
