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

Hurricane Florence has slowed significantly near the North Carolina
coast, but is expected to slowly shift west and make landfall around
daybreak near Cape Fear. Thereafter, Florence is expected to drift
west into the Pee Dee region of South Carolina into the weekend while
weakening. As Florence moves into South Carolina, the risk for
tropical storm force winds and excessive rainfall will increase.
Dangerous coastal conditions will also continue into the weekend. It
is important not to focus on the exact forecast track of Florence as
impacts will extend well away from the center. The worst conditions
are most likely to occur late this afternoon through Saturday night.

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

* WIND:
Protect against dangerous wind having possible significant impacts
across southeast South Carolina. Potential impacts in this area
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.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges and access routes
      impassable.
    - Travel by vehicle or on foot increasingly difficult. Danger of
      death or injury from falling objects such as trees or electric
      wires outside.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines, which could persist for hours
      or days.
    - Some poorly secured small craft could break loose from their
      moorings.

Elsewhere across southeast Georgia, little to no impact is anticipated
at this time.

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible significant
impacts across Berkeley, Charleston and Dorchester Counties.
Potential impacts include:
    - Moderate rainfall flooding could prompt some rescues.
    - Rivers and tributaries could quickly become swollen with
      swifter currents and overspill their banks in a few places,
      especially in normally vulnerable spots. Small streams, creeks,
      canals, and ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places could 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.

Elsewhere, protect against locally hazardous rainfall flooding having
possible limited impacts across southeast South Carolina. Little to no
impact is anticipated across southeast Georgia.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Charleston and Berkeley Counties. Potential impacts include:
    - Isolated tornadoes can hinder the execution of emergency plans.
    - Isolated locations could experience tornado damage, along with
      power and communications disruptions.
    - In isolated locations, tornadoes could damage trees, vehicles,
      boats and buildings, especially mobile homes and other poorly
      constructed structures.

Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across low-lying tidal areas of southeast South Carolina,
primarily north of Edisto Beach. Potential impacts in this area include:
    - Areas of inundation of saltwater along immediate shorelines and
      in low-lying spots farther inland near rivers and creeks, 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 normally vulnerable low
      spots.
    - Moderate to major beach erosion with heavy surf breaching
      dunes. Strong and numerous rip currents.
    - Minor to moderate damage to marinas, docks, boardwalks, and
      piers. Several small craft broken away from moorings,
      especially in unprotected anchorages. Some navigation aids
      possibly displaced well off station, creating difficult
      navigation near inlets and waterways.

Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated at this time.

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

* EVACUATIONS:
If evacuating, leave with a destination in mind and allow extra time
to get there. Take your emergency supplies kit. Gas up your vehicle
ahead of time.

Let others know where you are going prior to departure. Secure loose
items and pets in the car, and avoid distracted driving.

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

If you are relocating to safe shelter, leave as early as possible.
Allow extra time to reach your destination. Many roads and bridges
will be closed once strong winds arrive. Check the latest weather
forecast before departing and drive with caution.

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.
