DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 AM AST (0900 UTC), the center of Hurricane Maria was located
near latitude 14.6 North, longitude 59.5 West. Maria is moving
toward the west-northwest near 13 mph (20 km/h), and this motion
with a decrease in forward speed is expected through Tuesday night.
On the forecast track, the center of Maria will move across the
Leeward Islands late today and tonight and then over the
extreme northeastern Caribbean Sea Tuesday and Tuesday night.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Significant strengthening is forecast during the next 48
hours, and Maria is expected to become a dangerous major hurricane
before it moves through the Leeward Islands.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

The estimated minimum central pressure is 977 mb (28.85 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are first expected within portions of
the Leeward Islands by late today, with tropical storm conditions
beginning during the day today. Hurricane conditions are possible
within the hurricane watch area by Tuesday, with tropical storm
conditions possible tonight. Tropical storm conditions are possible
in the tropical storm watch area through tonight.

STORM SURGE: A dangerous storm surge accompanied by large and
destructive waves will raise water levels by as much as 5 to 7 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
central and southern 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
with isolated maximum amounts of 8 inches over the remaining
northern Leeward Islands from Barbuda to Anguilla, as well as the
Windward Islands and Barbados. Rainfall on all of these islands
could cause life-threatening flash floods and mudslides.

SURF: Swells generated by Maria are affecting the Lesser Antilles.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.
