Interests elsewhere in the Florida Peninsula, the Florida Keys, and

in the Carolinas should monitor the progress of Matthew.

A Hurricane Warning means that hurricane conditions are expected

somewhere within the warning area.  A warning is typically issued

36 hours before the anticipated first occurrence of tropical-storm-

force winds, conditions that make outside preparations difficult or

dangerous.  Preparations to protect life and property should be

rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are

expected somewhere within the warning area within 36 hours.

For storm information specific to your area in the United States,

including possible inland watches and warnings, please monitor

products issued by your local National Weather Service forecast

office. For storm information specific to your area outside the

United States, please monitor products issued by your National

meteorological service.

at 500 PM EDT (2100 utc), the eye of Hurricane Matthew was located

near latitude 26.2 north, longitude 78.6 west. The hurricane

is moving toward the northwest near 14 mph (22 km/h), and this

general motion is expected to continue tonight with a turn toward

the north-northwest early Friday.  On the forecast track, the

eye of Matthew should move near or over Freeport in the Bahamas

in the next hour or so, and move close to or over the East Coast

of the Florida Peninsula through Friday night.

Maximum sustained winds are near 140 mph (220 km/h) with higher

gusts.  Matthew is a category 4 hurricane on the Saffir-Simpson

hurricane wind scale.  Some fluctuations in intensity are likely

while the hurricane moves toward the coast of Florida.

Hurricane-force winds extend outward up to 60 miles (95 km) from the

center and tropical-storm-force winds extend outward up to 185 miles

(295 km).  Settlement Point in the Bahamas, recently reported a

sustained wind of 54 mph (87 km/h) with a gust of 62 mph (100

km/hr).

The minimum central pressure reported by a NOAA hurricane hunter

plane was 938 mb (27.70 inches).

Hazards affecting land

----------------------

wind:  hurricane conditions will continue over portions of the

northwestern Bahamas this evening.

Hurricane conditions are expected to first reach the Hurricane

Warning area in Florida this evening and will spread northward

within the warning area through Friday.  Tropical storm conditions

will continue to spread northward in the warning area along the

Florida East Coast tonight and Friday.

Hurricane conditions are expected to spread northward in the warning

area in Georgia and South Carolina Friday night and Saturday with

tropical storm conditions expected on Friday.

Winds increase rapidly in elevation in a tropical cyclone.

Residents in high-rise buildings should be aware that the winds at

the top of a 30-story building will be, on average, about one

Saffir-Simpson category higher than the winds near the surface.

Tropical storm conditions are expected in the Tropical Storm Warning

area in the Carolinas on Friday night and Saturday.

Storm surge:  the combination of a dangerous storm surge and large

and destructive waves could raise water levels by as much as the

following amounts above normal tide levels...

Northwestern Bahamas...10 to 15 feet

The water could reach the following heights above ground if the peak

surge occurs at the time of high tide...

Sebastian Inlet, Florida, to Edisto Beach, South Carolina, including

portions of the St. Johns River...7 to 11 ft

Edisto Beach to South Santee River, South Carolina...4 to 6 ft

Deerfield Beach to Sebastian Inlet, Florida...4 to 6 ft

South Santee River, South Carolina, to Cape Fear, North Carolina...2

to 4 ft

Virginia Key to Deerfield Beach, Florida...1 to 3 ft

Surge-related flooding depends on the relative timing of the surge

and the tidal cycle, and can vary greatly over short distances.

Large waves generated by Matthew will cause water rises to occur

well in advance of and well away from the track of the center.

The combination of a dangerous storm surge and the tide will cause

normally dry areas near the coast to be flooded by rising waters

moving inland from the shoreline.  There is a danger of life-

threatening inundation during the next 36 hours along the Florida

East Coast, the Georgia coast, and the South Carolina coast from

Deerfield Beach, Florida, to South Santee River, South Carolina.

There is the possibility of life-threatening inundation during the

next 48 hours from north of South Santee River, South Carolina, to

Cape Fear, North Carolina. For a depiction of areas at risk, please

see the prototype National Weather Service storm surge watch/warning

graphic. For information specific to your area, please see products

issued by your local National Weather Service forecast office.

The prototype storm surge watch/warning graphic is a depiction of

areas that would qualify for inclusion under a storm surge watch or

warning currently under development by the National Weather Service

and planned for operational use in 2017.  The prototype graphic is

available at hurricanes.Gov.

Rainfall:  Matthew is expected to produce total rainfall amounts in

the following areas:

The central and northern Bahamas...8 to 12 inches, isolated 15

inches

coastal eastern Florida, Georgia, South Carolina, and southeast

North Carolina....5 to 10 inches, isolated 12 inches

Rainfall should diminish across central and eastern Cuba with

isolated additional amounts of 1 to 2 inches possible through this

evening.

Tornadoes:  an isolated tornado or two is possible along the

east-central Florida coast tonight.

Surf:  swells generated by Matthew will continue to affect portions

of the north coast of Cuba and the Bahamas during the next few days,

and will spread northward along the East Coast of Florida and the

southeast U.S. Coast through the weekend.  These swells will likely

cause life-threatening surf and rip current conditions.  Please

consult products from your local weather office.

Rather than me constantly writing into the list every four hours or so, you
can find

updated information by going to:

http://braille.wunderground.com <http://braille.wunderground.com/> 

Don't worry about the (braille) portion of the site name sounding weird, you
can

still access the site with any Internet-capable  device anytime you wish.
Just go

to the above link, and click on the (tropical storms) link, then on the page
that

appears, click on the (public advisory) link, and scroll down the page.
You'll find

information much like what I just gave you above. I believe they update it
every

four hours or so. Stay safe everyone.

Mike
