DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the eye of Hurricane Erin was located
near latitude 20.3 North, longitude 65.1 West. Erin is moving toward
the west-northwest near 14 mph (22 km/h). This motion is expected to
continue through Sunday with a decrease in forward speed. A turn
more northward is expected to occur on Monday into Tuesday. On the
forecast track, the center of Erin is expected to begin moving away
from the Virgin Islands and Puerto Rico on Sunday, and pass to the
east of the Turks and Caicos Islands and the southeastern Bahamas
Sunday night and Monday.

NOAA Hurricane Hunter and Air Force Reserve reconnaissance data
indicates that maximum sustained winds have decreased to near 140
mph (220 km/h) with higher gusts. Erin is a category 4 hurricane on
the Saffir-Simpson Hurricane Wind Scale. Fluctuations in intensity
are expected over the next day or two due to inner-core structural
changes with Erin.

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

The estimated minimum central pressure measured by Air Force reserve
dropsonde data is 937 mb (27.67 inches)

HAZARDS AFFECTING LAND
----------------------
Key messages for Erin can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC.

RAINFALL: The outer bands of Erin are expected to produce areas of
heavy rainfall tonight into Sunday across the northern Leeward
Islands, the Virgin Islands, and Puerto Rico. Rainfall totals of 2
to 4 inches, with isolated totals of 6 inches, are expected. This
rainfall may lead to isolated and locally considerable flash and
urban flooding, along with landslides or mudslides.

For a complete depiction of forecast rainfall and flash flooding
associated with Erin, please see the National Weather Service Storm
Total Rainfall Graphic, available at
hurricanes.gov/graphics_at5.shtml?rainqpf

WIND: Tropical storm conditions are possible within the watch
area by early Saturday.

SURF: Swells generated by Erin will begin affecting portions of the
northern Leeward Islands, the Virgin Islands and Puerto Rico by this
weekend, and will likely spread to the western Atlantic next week.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
forecast office.
