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

Hurricane Florence continues to creep generally westward across far
southern North Carolina this afternoon. Despite the center of the
storm moving further from the area, life threatening impacts from
Florence, including extreme storm surge, catastrophic and possibly
historic flooding rains, and damaging winds continue. The very slow
westward motion of Florence will prolong these dangerous conditions
across Eastern North Carolina into Saturday.

Hurricane force winds in excess of 74 mph remain possible this
afternoon for coastal areas of southeast North Carolina. Elsewhere,
tropical storm force wind gusts will continue. The saturated ground
and long duration of high winds will continue to bring down trees and
lead to widespread power outages.

The potential for historic flooding continues across southeastern
North Carolina due to the prolonged period of heavy rainfall. The area
has received as much as 10 to 15 inches over the last 24 hours, and
additional rainfall amounts of 1 to 2 FEET will still be possible
through the weekend. Highest rainfall totals are expected across the
southern half to the area. These rainfall amounts will likely cause
catastrophic flash flooding, followed by significant and prolonged
river flooding lasting well into next week.

Major to potentially record river flooding is expected for rivers and
streams primarily over Duplin, Onslow, Carteret, and Craven Counties
where the heaviest rain is likely to fall. Elsewhere all other rivers
and streams are vulnerable to moderate or major flooding with this
storm. Many will reach flood stage as early as tonight, and will
continue to rise well into next week. Given the generally slow rise of
area rivers, most won't crest until mid to late next week extending
the impacts from this long duration flood event.

Extreme storm surge impacts will continue with Hurricane Florence.
Inundation of up to 7 to 11 feet above ground with locally higher
amounts will continue for waterways mainly along and south of the
Tar/Pamlico River and the Pamlico Sound, including the Bay and Neuse
Rivers. Catastrophic storm surge has occurred for areas along the
Neuse River, including New Bern where hundreds of water rescues have
occurred and are still underway. Moderate to significant storm surge
flooding will continue over the northern coast with inundation of 3 to
6 feet above ground.

High surf and large breaking waves will likely result in extreme beach
erosion and ocean overwash along the North Carolina coast mainly south
of Cape Hatteras, mainly around the times of high tides into Saturday.

The threat for tornadoes will continue today.

Very dangerous marine conditions, with extreme seas of 15 to 25 feet,
will continue into the weekend. A high threat of rip currents and
large and dangerous breaking waves in the surf zone will produce
extremely hazardous beach conditions.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
areas adjacent to the Pamlico Sound, Neuse, Bay, and Pamlico Rivers.
Remain well away from life-threatening surge having additional
devastating impacts. If realized, these impacts include:
    - Widespread deep inundation, with storm surge flooding greatly
      accentuated by powerful battering waves. Structural damage to
      buildings, with many washing away. Damage greatly compounded
      from considerable floating debris. Locations may be
      uninhabitable for an extended period.
    - Near-shore escape routes and secondary roads washed out or
      severely flooded. Flood control systems and barriers may become
      stressed.
    - Extreme beach erosion. New shoreline cuts possible.
    - Massive damage to marinas, docks, boardwalks, and piers.
      Numerous small craft broken away from moorings with many lifted
      onshore and stranded.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
much of eastern North Carolina. Remain well guarded against
life-threatening flood waters having additional devastating impacts.
These impacts include:
    - Extreme rainfall flooding may prompt numerous evacuations and
      rescues.
    - Rivers and tributaries may overwhelmingly overflow their banks
      in many places with deep moving water. Small streams, creeks,
      canals, and ditches may become raging rivers. Flood control
      systems and barriers may become stressed.
    - Flood waters can enter numerous structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Numerous places where flood waters may cover escape
      routes. Streets and parking lots become rivers of raging water
      with underpasses submerged. Driving conditions become very
      dangerous. Numerous road and bridge closures with some weakened
      or washed out.

* WIND:
Potential impacts from the main wind event are now unfolding across
much of southeastern North Carolina. Remain well sheltered from
life-threatening wind having additional extensive impacts.
These impacts include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Potential impacts from the main wind event are also now unfolding
across northeast North Carolina. Remain well sheltered from
dangerous wind having additional limited to significant impacts.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across coastal
eastern North Carolina. Remain well braced against a dangerous tornado
event having additional 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.

Potential impacts from tornadoes are still unfolding across the coastal
plain of eastern North Carolina. Remain well braced against a tornado event
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.

If you lose power, use your cell phone 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.

NEXT UPDATE
-----------

The next local statement will be issued by the National Weather
Service in Newport/Morehead City NC around 5 PM EDT, or sooner if
conditions warrant.
