meteorological service.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 200 AM EDT (0600 UTC), radar data from Guantanamo, Cuba, along
with reports from an Air Force Reserve Hurricane Hunter aircraft,
indicate that the eye of Hurricane Matthew was located near latitude
20.7 North, longitude 74.4 West. Matthew is moving toward the north
near 8 mph (13 km/h), and this general motion is expected to
continue overnight. A turn toward the north-northwest is expected
today, followed by a northwest turn Wednesday night. Matthew
will be moving across the Bahamas through Thursday, and is expected
to be very near the east coast of Florida by Thursday evening.

Maximum sustained winds have decreased to near 125 mph (205 km/h)
with higher gusts. Matthew is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity
are possible during the next couple of days, but Matthew is expected
to remain a powerful hurricane through at least Thursday night.

Hurricane-force winds extend outward up to 45 miles (75 km) from
the center and tropical-storm-force winds extend outward up to 175
miles (280 km).

The minimum central pressure estimated from reconnaissance
aircraft data is 962 mb (28.41 inches).



1. Matthew is likely to produce devastating impacts from storm
surge, extreme winds, heavy rains, flash floods, and/or mudslides in
portions of the warning areas in Haiti, Cuba, and the Bahamas.
Please consult statements from the meteorological services and other
government officials in those countries.

2. When a hurricane is forecast to take a track roughly parallel
to a coastline, as Matthew is forecast to do from Florida through
South Carolina, it becomes very difficult to estimate impacts this
far in advance. For example, only a small deviation of the track to
the left of the NHC forecast could bring the core of a major
hurricane onshore, while a small deviation to the right could keep
all of the hurricane-force winds offshore. It will likely take
another day or so for the potential impacts of Matthew in the United
States to clarify.

3. Tropical storm or hurricane conditions could affect portions of
Florida north of the current Hurricane Watch area, Georgia, South
Carolina, and North Carolina later this week or this weekend, even
if the center of Matthew remains offshore. It is too soon to
specify what, if any, direct impacts Matthew might have on the
remainder of the U.S. east coast farther to the north. At a
minimum, very dangerous beach and boating conditions are likely
along much of the U.S. east coast later this week and weekend.
