DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 200 AM EDT (0600 UTC), the center of Hurricane Matthew was
located by NOAA Doppler weather radars and an Air Force Reserve
Hurricane Hunter aircraft near latitude 34.8 North, longitude 75.8
West. Matthew is moving toward the northeast near 16 mph (27 km/h).
This motion is expected to continue early this morning, followed
by a turn toward the east-northeast by this afternoon. An eastward
motion is expected by tonight and Monday. On the forecast track,
the center of Matthew should move near or just south of the coast of
North Carolina this morning and east of the North Carolina coast by
this afternoon.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Little change in strength is forecast during the next
several hours, although Matthew should become a post-tropical
cyclone later this morning. Weakening is expected by this afternoon
and Monday.
Hurricane-force winds extend outward up to 70 miles (110 km) mainly
to the southwest of the center, and tropical-storm-force winds
extend outward up to 240 miles (390 km). A wind gust to 69 mph (111
km/h) was recently reported at Elizabeth City, North Carolina, and a
wind gust to 59 mph (94 km/h) was reported at Morehead City, North
Carolina, during the past hour.
The estimated minimum central pressure based on a combination of
aircraft data and surface observations is 983 mb (29.03 inches).
HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane and tropical storm conditions are expected to
continue over the hurricane warning area this morning and then
subside by this afternoon.
Hurricane conditions are possible within the Hurricane Watch and
Tropical Storm Warning area in North Carolina later this morning,
with tropical storm conditions continuing well inland for the
next few hours.
STORM SURGE: The combination of a dangerous storm surge, the tide,
and large and destructive waves will cause normally dry areas near
the coast to be flooded by rising waters moving inland from the
shoreline. The water could reach the following heights above ground
if the peak surge occurs at the time of high tide...
Surf City to Duck, North Carolina, including portions of the Pamlico
and Albemarle Sounds...3 to 5 ft
Along the Georgia and South Carolina coasts southwest of Matthew's
center, inundation caused by Matthew's storm surge will slowly
recede today.
The deepest water will occur along the immediate coast in areas of
onshore winds. 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. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.
There is a danger of life-threatening inundation during the next 36
hours along the coast from Surf City to Duck, North Carolina,
including portions of the Pamlico Sound. 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 rain accumulations of
8 to 12 inches from northeast South Carolina into northeast North
Carolina and southeast Virginia, with possible isolated totals of 20
inches possible. This rainfall is producing record-breaking flooding
over portions of eastern North Carolina, and it may result in
life-threatening flooding and flash flooding elsewhere across the
region.
SURF: Swells generated by Matthew will continue to affect much of
the coast of the southeastern United States through early next week.
These swells will likely cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
