DISCUSSION AND 48-HOUR OUTLOOK
At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone
Hermine was located near latitude 37.2 North, longitude 69.6 West.
The post-tropical cyclone is moving toward the east-northeast near
10 mph (17 km/h). A turn toward the north with a decrease in
forward speed is expected later today, followed by a slow
north-northwestward motion through Monday. On the forecast track,
the center of Hermine will meander slowly offshore of the
mid-Atlantic coast for the next couple of days.
Maximum sustained winds have increased to near 70 mph (110 km/h)
with higher gusts. Hermine is expected to be at or near hurricane
strength during the next 48 hours.
Tropical-storm-force winds extend outward up to 205 miles (335 km)
from the center.
The minimum central pressure estimated from Air Force reconnaissance
aircraft observations is 999 mb (29.50 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions will spread northward within the
warning area along the Atlantic coast through Monday. Tropical
storm conditions are possible in the watch area by Monday.
STORM SURGE: The combination of a storm surge and the tide will
cause normally dry areas near the coast to be flooded by rising
waters moving inland from the shoreline. Along the immediate
coastline, the surge will be accompanied by large and dangerous
waves. There is a danger of life-threatening inundation within the
next 36 hours from Cape Charles, Virginia, to Sandy Hook, New
Jersey. Persons within these areas should take all necessary
actions to protect life and property from rising water. Promptly
follow all instructions, including evacuation orders, from local
officials. There is also the possibility of life-threatening
inundation during the next 48 hours at many coastal locations
between Sandy Hook, New Jersey, and Bridgeport, Connecticut,
including Long Island.
For a depiction of areas at risk, please see the Prototype Storm
Surge Watch/Warning graphic, which displays 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
The water could reach the following heights above ground if the
peak surge occurs at the time of high tide...
North Carolina sounds and northern Outer Banks...1 to 2 feet
Cape Charles to Chincoteague, VA...2 to 4 feet
Chincoteague, VA to Atlantic City, NJ...3 to 5 feet
Atlantic City to Sandy Hook, NJ...2 to 4 feet
Sandy Hook, NJ to Bridgeport, CT including Long Island...1 to 3
RAINFALL: Heavy rainfall associated with Hermine will remain
offshore through Monday/Labor Day. Hermine will produce rainfall
amounts of 1 to 2 inches over southern New England from Long Island
to eastern Massachusetts, and additional rainfall of one inch or
less along the coastline of the mid-Atlantic states.
SURF: Large waves generated by Hermine will affect the U.S. east
coast from the mid-Atlantic states and expand northward along the
coast of southern New England through Monday. These waves are
likely to cause life-threatening surf and rip current conditions,
and significant beach erosion. Please consult products from your
local weather office.
