winds, conditions that make outside preparations difficult or
dangerous.

expected somewhere within the warning.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere in southeastern Newfoundland should monitor the

products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the center of Hurricane Larry was located
near latitude 30.9 North, longitude 61.1 West. Larry is moving
toward the north-northwest near 16 mph (26 km/h), and a turn toward
the north-northwest and north with an increase in forward speed is
forecast today, with a faster northeastward motion expected by
Friday.  On the forecast track, the center of Larry should pass
east of Bermuda today, and move near or over southeastern
Newfoundland Friday night or early Saturday morning.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts.  Gradual weakening is forecast during the next couple
of days, but Larry is expected to remain a hurricane during that
time. Larry should become an extratropical cyclone early Saturday,
after passing by Newfoundland, then weaken further while it passes
southeast of Greenland Sunday night.  Larry is expected to be
absorbed by a larger baroclinic system east of Greenland Monday.

Larry remains very large, with Hurricane-force winds extending
outward up to 90 miles (150 km) from the center and
tropical-storm-force winds extending outward up to 220 miles (350
km) from the center.

The estimated minimum central pressure is 969 mb (28.62 inches).


HAZARDS AFFECTING LAND

later this morning.

Hurricane conditions are possible within the hurricane watch area in
southeastern Newfoundland Friday night with tropical storm
conditions possible by late Friday. Tropical storm conditions are
possible in the tropical storm watch area in southeastern
Newfoundland by late Friday.

SURF:  Swells generated by Larry will continue to affect the Leeward
Islands, portions of the Greater Antilles, the Bahamas, and Bermuda
through the end of the week. Significant swells from Larry will
continue affecting the east coast of the United States and Atlantic
Canada through the end of the week. These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.

RAINFALL:  Outer rain bands from Hurricane Larry may periodically
impact Bermuda Thursday. Significant rainfall totals are currently
not expected, however briefly heavy rain rates within these bands
may result in an inch or two of rain through Thursday.  Heavy rains
from Larry will move quickly across eastern New Foundland Friday
night, producing 1 to 2 inches of rain.
