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

Dangerous Hurricane Dorian will track north very close to the
Florida coast through Wednesday and very near the South Carolina and
Georgia coasts Wednesday Night through Thursday. The hurricane will
bring an increased risk for strong winds, storm surge inundation,
flash flooding, strong rip currents, and dangerous marine conditions
to the region. The combination of significant storm surge inundation
and heavy rainfall could enhance the risk for flash flooding,
especially along the lower South Carolina coast, including Downtown
Charleston and the nearby coastal communities.

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

* SURGE:
Protect against life-threatening surge having possible extensive
impacts across the coastal counties of southeast South Carolina and
southeast Georgia. Potential impacts in this area include:
    - Large areas of deep inundation of saltwater along immediate
      shorelines and in low-lying spots farther inland near rivers
      and creeks, with storm surge flooding accentuated by battering
      waves. Structural damage to buildings, with several washing
      away. Damage compounded by floating debris. Locations may be
      uninhabitable for an extended period.
    - Large sections of near-shore escape routes and secondary roads
      washed out or flooded and impassable. Flood control systems and
      barriers could become stressed.
    - Severe beach erosion with significant dune loss.
    - Major damage to marinas, docks, boardwalks, and piers. Many
      small craft broken away from moorings, especially in
      unprotected anchorages, with some lifted onshore and stranded.
    - Drinking water and sewer services negatively impacted.
    - Hazardous containers and materials possibly present in surge
      waters.

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

* WIND:
Protect against life-threatening wind having possible extensive
impacts across areas mainly along and east of Interstate 95.
Potential impacts in this area include:
    - Considerable roof damage to sturdy buildings, with some window,
      door, and garage door failures leading to structural damage.
      Mobile homes severely damaged, with some destroyed. Damage
      accentuated by airborne projectiles. Some locations may be
      uninhabitable for weeks.
    - Danger of death or injury from falling objects and airborne
      projectiles outside.
    - Large trees snapped or uprooted.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded locations. Several bridges and access routes
      impassable.
    - Large areas with power and communications outages, which could
      persist for days.
    - Several secured small craft could break free from moorings.

Also, protect against dangerous wind having possible limited to
significant impacts across interior portions of southeast South
Carolina and southeast Georgia.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across coastal portions of southeast South Carolina
and southeast Georgia. Potential impacts include:
    - Major rainfall flooding could prompt many rescues.
    - Rivers and tributaries could rapidly overflow their banks in
      multiple locations. Small streams, creeks, canals, ditches may
      become dangerous rivers. Flood control systems and barriers
      could become stressed.
    - Flood waters could enter many structures within multiple
      communities; some structures become uninhabitable or are washed
      away. Flood waters could cover multiple escape routes. Streets
      and parking lots become rivers of moving water with underpasses
      submerged. Driving conditions become dangerous. Many road and
      bridge closures with some weakened or washed out.
    - Drinking water and sewer services could be negatively impacted.
    - Hazardous containers and materials could possibly be present in
      flood waters.

Protect against dangerous rainfall flooding having possible limited
to significant impacts across interior portions of southeast South
Carolina and southeast Georgia.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across coastal areas of southeast South Carolina and southeast Georgia.
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.

* OTHER COASTAL HAZARDS:
Severe beach erosion, high surf with breakers of 5 feet or greater,
and strong rip currents will occur at the beaches of southeast South
Carolina and southeast Georgia. A High Surf Advisory remains in effect
and a there is also a High Risk of Rip Currents.

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

For those not under evacuation orders, assess the risk from wind,
falling trees, and flooding at your location. If you decide to move,
relocate to a safer location nearby. If you do not relocate, help keep
roadways open for those under evacuation orders.

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.

* 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.

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.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.
