DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM EDT (0300 UTC), the center of Hurricane Gert was located
near latitude 34.8 North, longitude 70.3 West.  Gert is moving
toward the northeast near 15 mph (24 km/h) and this motion is
expected to continue with a significant increase in forward speed
during the next couple of days.

Maximum sustained winds have increased to near 85 mph (140 km/h)
with higher gusts.  Some additional strengthening is possible
tonight and Wednesday.  After that, Gert is expected to weaken,
with the cyclone becoming an extratropical low by Thursday night.

Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km).

The estimated minimum central pressure is 979 mb (28.91 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Gert will spread northward along the
east coast of the United States from North Carolina northward to
Long Island during the next couple of days, with the first impacts
expected tonight.  Swells are also expected to affect Bermuda
during the next couple of days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
