DISCUSSION AND OUTLOOK
At 1100 AM EDT (1500 UTC), the center of Hurricane Dorian was
located near latitude 35.7 North, longitude 74.8 West. Dorian is
moving toward the northeast near 17 mph (28 km/h) and this general
motion with an increase in forward speed is expected through
Saturday night. On the forecast track, the center of Dorian will
move away from the coast of North Carolina during the next several
hours. The center should move to the southeast of extreme
southeastern New England tonight and Saturday morning, and then
across Nova Scotia late Saturday or Saturday night.
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Slow weakening is expected through Saturday. After that,
Dorian is forecast to become a post-tropical cyclone with
hurricane-force winds by Saturday night as it approaches Nova
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 220 miles
(350 km). About an hour ago, a Weatherflow station at Avon Sound,
North Carolina reported a sustained wind of 83 mph (134 km/h) and a
wind gust of 98 mph (158 km/h).
The minimum central pressure based on Air Force Reserve Hurricane
Hunter data and surface observations is 957 mb (28.26 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions should end along portions of the
North Carolina coast during the next few hours. Tropical storm
conditions should continue on the southeastern coast of Virginia for
the next several hours, and are expected to spread across other
portions of the the Mid-Atlantic states later today. Tropical
storm conditions are also expected in the warning area over portions
of extreme southeastern Massachusetts tonight or early Saturday,
and in the warning area in Maine Saturday afternoon
Hurricane conditions are possible in Nova Scotia and Prince
Edward Island Saturday, and tropical storm conditions are possible
over other portions of the Canadian Maritime and Atlantic areas
Saturday and Saturday night.
STORM SURGE: 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. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Salter Path to Duck NC, including Pamlico and Albemarle
Sounds and the Neuse and Pamlico Rivers...4 to 7 ft
Duck NC to Poquoson VA, including Hampton Roads...2 to 4 ft
Water levels could begin to rise well in advance of the arrival of
strong winds. The surge will be accompanied by large and
destructive waves. Surge-related flooding depends on the how close
the center of Dorian comes to the coast, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
Storm Surge is likely in the Gulf of St. Lawrence, the Southwest
Coast of Newfoundland, and Eastern Nova Scotia.
RAINFALL: Dorian is expected to produce the following rainfall
totals through Saturday:
Northeastern North Carolina into far southeast Virginia...Additional
1 to 4 inches, isolated storm totals 10 inches.
Extreme Southeastern New England...2 to 4 inches.
Nova Scotia and Prince Edward Island...3 to 5 inches.
Newfoundland...1 to 2 inches
This rainfall may cause life-threatening flash floods
SURF: Large swells will affect much of the southeastern United
States coast from northern Florida through North Carolina 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.
