SITUATION OVERVIEW
------------------

Isaias has regained hurricane strength, and has made landfall near
Ocean Isle Beach. Isaias will begin to gradually weaken as it
passes through the inner coastal plain of eastern North Carolina
overnight and into tomorrow morning.

Tropical storm force winds will continue overnight. Downed trees and
scattered power outages are possible through the morning. Tornadoes
are possible tonight through the morning, leading to locally enhanced
damage, and a Tornado Watch has been issued for all of eastern North
Carolina.

Life-threatening storm surge is expected along portions of area
beaches and coastlines, as well as for low lying areas adjacent to the
sounds and tidal rivers. Low lying properties and roadways could be
inundated and damaged, and dunes could be overtopped as wave action
enhances the storm surge risk along the beaches.

Heavy rainfall will continue to overspread the area. Localized
flooding of low lying and poor drainage areas is possible mainly along
and west of US Highway 17. River levels are likely to reach and exceed
flood stage in the next few days, though widespread flooding is not
expected.

The threat for stronger and more frequent rip currents will continue
for area beaches over the next couple days, leading to extremely
dangerous conditions for swimming.

Dangerous marine conditions are also occurring, with strong winds and
seas building to 15 to 20 feet creating treacherous conditions for
mariners.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
eastern North Carolina. Remain well sheltered from dangerous
wind having additional significant impacts. If realized, these
impacts include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.

Potential impacts from the main wind event are also now unfolding
across the Outer Banks. Remain well sheltered from
hazardous wind having possible limited impacts.

* SURGE:
Potential impacts from the main surge event are for area beaches north
of Ocracoke Inlet, the Pamlico Sound, Neuse River, Pamlico River,
Pungo River, and associated tributaries. Remain well away from life-threatening
surge having possible significant impacts. If realized, these impacts include:
    - Areas of inundation with storm surge flooding accentuated by
      waves. Damage to several buildings, mainly near the coast.
    - Sections of near-shore escape routes and secondary roads become
      weakened or washed out, especially in usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Potential impacts from the main surge event are also now unfolding
across the beaches south of Ocracoke Inlet. Remain well away from locally
hazardous surge having possible limited impacts.

Elsewhere across Eastern North Carolina, little to no impact is
anticipated.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across eastern
North Carolina. Remain well braced against a dangerous tornado event
having possible significant impacts. If realized, these impacts include:
    - The occurrence of scattered tornadoes can hinder the execution
      of emergency plans during tropical events.
    - Several places may experience tornado damage with a few spots
      of considerable damage, power loss, and communications failures.
    - Locations could realize roofs torn off frame houses, mobile
      homes demolished, boxcars overturned, large trees snapped or
      uprooted, vehicles tumbled, and small boats tossed about.
      Dangerous projectiles can add to the toll.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
eastern North Carolina mainly west of US Highway 17. Remain well guarded
against dangerous flood waters having possible significant impacts.
If realized, these impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals, and
      ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

Potential impacts from the flooding rain are still unfolding across
coastal eastern North Carolina. Remain well guarded against locally
hazardous flood waters having possible limited impacts.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Do not enter evacuated areas until officials have given the all clear
to return.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.

Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
check-ins.

Do not be a thrill seeker or risk your life for senseless photos or
videos.

If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
