Monday night a Hurricane Warning was extended westward to include Puerto Rico and the Virgin Islands. Hurricane Irma was centered as of 11 p.m. AST/EDT about 410 miles (660 km) east of the Leeward Islands, moving toward the west near 13 mph (20mkm/h).

The general motion is expected to continue, followed by a turn toward the west-northwest later today. On the forecast track, the center of Irma will move near or over portions of the northern Leeward Islands tonight and early Wednesday.

A Hurricane Warning is in effect for Antigua, Barbuda, Anguilla, Montserrat, St. Kitts, Nevis, Saba, St. Eustatius, Sint Maarten, Saint Martin, Saint Barthelemy, British Virgin Islands, U.S. Virgin Islands, Puerto Rico, Vieques, and Culebra. A Hurricane Watch and Tropical Storm Warning is in effect for Guadeloupe. A Tropical Storm Watch is in effect for Dominica.

Maximum sustained winds are near 140 mph (220 km/h) with higher gusts – a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional strengthening during the next 48 hours is forecast. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km).

Users are reminded to not focus on the exact forecast track, especially at the longer ranges, since the average NHC track errors are about 175 and 225 statute miles at days 4 and 5, respectively.
