DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the center of Hurricane Ernesto was
located near latitude 32.6 North, longitude 64.6 West. Ernesto is
moving toward the north-northeast near 9 mph (15 km/h), and this
general motion is expected today. A faster northeastward motion is
then expected late this weekend into early next week. On the
forecast track, the center of Ernesto is expected to slowly depart
Bermuda today and move near or east of Newfoundland Monday night.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Little change in strength is forecast today. Some
re-intensification is possible late in the weekend before weakening
begins on Monday.

Ernesto is a large tropical cyclone. Hurricane-force winds extend
outward up to 70 miles (110 km) from the center and tropical-storm-
force winds extend outward up to 240 miles (390 km).

The estimated minimum central pressure based on dropsonde data is
974 mb (28.76 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Ernesto can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC
and on the web at hurricanes.gov/text/MIATCDAT5.shtml.

WIND: Hurricane conditions are expected on Bermuda through the
next several hours. Due to Ernesto's large size and slow motion,
strong winds will continue on the island through most of today into
this evening.

STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding on Bermuda in areas of onshore winds.
Near the coast, the surge will be accompanied by large and
destructive waves.

RAINFALL: Ernesto is expected to produce total rain accumulations of
6 to 9 inches or 150 to 225 mm on Bermuda. This rainfall will likely
result in considerable life-threatening flash flooding, especially
in low-lying areas on the island.

SURF: Swells generated by Ernesto are affecting portions of the the
Bahamas, Bermuda, and the east coast of the United States. These
swells will likely reach portions of Atlantic Canada today.
Life-threatening surf and rip current conditions are likely in these
areas during the next couple of days. Please consult products from
your local weather office, and stay out of the water if advised by
lifeguards.
