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

Dangerous Hurricane Dorian will move offshore of the Florida east
coast through Wednesday and offshore of the South Carolina and Georgia
coast 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:
Prepare for life-threatening surge having possible extensive impacts
across across the coastal counties of Southeast South Carolina and
Southeast Georgia.
    - 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:
Prepare for life-threatening wind having possible extensive impacts for
areas roughly 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, prepare for dangerous wind having possible limited to
significant impacts across interior Southeast South Carolina and
Southeast Georgia.

* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across coastal areas 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.

Prepare for locally hazardous rainfall flooding having possible
limited impacts across interior Southeast South Carolina and Southeast
Georgia.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across
the 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 5 feet or greater, and strong
rip currents will occur across the beaches of Southeast South Carolina and
Southeast Georgia. A High Surf Advisory is in effect.

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, follow designated evacuation routes. Seek traffic
information on roadway signs, the radio, and from official sources.

* OTHER PREPAREDNESS INFORMATION:
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging wind
gusts, storm surge, and tornadoes extend well away from the center of
the storm.

If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.

If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.
