DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 PM EDT (2100 UTC), the center of Post-Tropical Cyclone
Matthew was located near latitude 35.4 North, longitude 72.0 West.
The post-tropical cyclone is moving toward the east-northeast near
15 mph (24 km/h), and this general motion is expected to continue
tonight.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Some weakening is forecast tonight, and the low is expected
to be absorbed within a frontal boundary on Monday.

Hurricane-force winds extend outward up to 90 miles (150 km),
primarily to the southwest and west of the center, and
tropical-storm-force winds extend outward up to 240 miles (390 km).

The estimated minimum central pressure based on data from a NASA
Global Hawk aircraft is 988 mb (29.18 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Wind gusts to tropical storm force will continue over
portions of the Outer Banks tonight.

STORM SURGE:  Dangerously high water levels over portions of the
Outer Banks will gradually subside overnight and early Monday.
Consult products issued by your local National Weather Service
forecast office for additional information.

RAINFALL: Life-threatening flooding will continue over portions
of eastern North Carolina that have received record rains from
Matthew.  Consult products issued by your local National Weather
Service forecast office for additional information and warnings.

SURF:  Swells generated by Matthew will continue to affect much of
the southeastern and Mid-Atlantic coasts of the United States
during the next couple of days.  These swells will likely cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

POST-TROPICAL CYCLONE MATTHEW DISCUSSION NUMBER  47
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL142016
500 PM EDT SUN OCT 09 2016

Dropsonde data from a NASA Global Hawk mission into Matthew today
indicate that the post-tropical cyclone has not weakened.  The
observations continue to show a band of 60-65 kt winds to the
southwest and west of the center.  Matthew is moving east-
northeastward at about 13 kt, and an east-northeastward motion
within the mid-latitude westerlies should continue through
tonight.  Matthew is forecast by the global models to weaken and be
absorbed within a frontal boundary on Monday, and the NHC forecast
follows suit.  It should be noted that a strong baroclinic low is
expected to develop along the same frontal boundary near Nova
Scotia on Monday.

Winds over the Outer Banks of North Carolina have gradually
diminished this afternoon, and the tropical storm warning has been
discontinued. Dangerously high water levels over portions of the
Outer Banks will gradually subside overnight and early Monday.
Based on these trends, this will be the last NHC advisory on
Matthew.  For additional information on the elevated water levels in
the Outer Banks and the ongoing freshwater flooding in eastern North
Carolina, see products and warnings issued by your local National
Weather Service forecast office.  Additional information on Matthew
can also be found in High Seas Forecasts issued by the National
Weather Service, under AWIPS header NFDHSFAT1 and WMO header FZNT01
KWBC.
