WATCHES AND WARNINGS

There are no coastal tropical cyclone watches or warnings in effect.

Interests in Ireland should monitor products issued by Met Eireann,

by the UK Met Office.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Ophelia was
located near latitude 41.6 North, longitude 16.0 West. Ophelia is
moving toward the north-northeast near 38 mph (61 km/h), and this
motion is expected to continue during the next 24 to 48 hours. On
the forecast track, the center of the post-tropical cyclone will
approach Ireland tomorrow morning. However, strong winds and rains
should begin earlier.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Additional weakening is forecast, but Ophelia should
maintain hurricane force winds until it reaches Ireland.

Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 150 miles
(240 km).

The estimated minimum central pressure is 973 mb (28.74 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Gale-force winds are expected to begin across southern
Ireland by early Monday morning and gradually spread northward
across the country during the day. Hurricane-force winds are
expected to reach the southern portions of Ireland by Monday
afternoon and spread inland across the country into Monday night.
Preparations to protect lives and property should be rushed to
completion by this afternoon.

Wind speeds atop and on the windward sides of hills and mountains
are often up to 30 percent stronger than the near-surface winds
indicated in this advisory, and in some elevated locations could be
even greater.

RAINFALL: Ophelia is expected to produce rainfall amounts of 2 to
3 inches (50 mm to 75 mm) with isolated totals near 4 inches (100
mm) through Tuesday across western Ireland and Scotland. Across
eastern Ireland, rainfall amounts will average around 1 inch (25 mm)
or less.

STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding near and to the east of where the
center of the post-tropical cyclone makes landfall. Near the coast,
the surge will be accompanied by large and destructive waves.


NEXT ADVISORY
-------------
Next complete advisory at 500 PM AST.
