DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 800 PM AST (0000 UTC), the eye of Hurricane Maria was located
near latitude 15.3 North, longitude 61.1 West. Maria is moving
toward the west-northwest near 9 mph (15 km/h), and this general
motion is expected to continue through Wednesday. On the forecast
track, the core of Maria will move near Dominica and the adjacent
Leeward Islands during the next few hours, over the extreme
northeastern Caribbean Sea the remainder of tonight and Tuesday, and
approach Puerto Rico and the Virgin Islands Tuesday night and
Wednesday.

Maximum sustained winds are near 160 mph (260 km/h) with higher
gusts. Maria is a category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some additional strengthening is possible
tonight, but some fluctuations in intensity are likely during the
next day or two.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 125 miles
(205 km).

The estimated minimum central pressure based on Air Force Hurricane
Hunter data is 925 mb (27.32 inches).
