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

Hurricane Dorian remains a dangerous hurricane. Dorian is forecast
to continue north off the east coast of Georgia, then turn north-
northeast as it passes near the South Carolina coast later this
morning and through the afternoon. Hazardous conditions will continue
to spread over southeast South Carolina including damaging winds, flash
flooding, strong rip currents, and severe beach erosion. The combination
of storm surge inundation and heavy rainfall will enhance the risk for
flash flooding along the southeast South Carolina coast, including
Downtown Charleston and nearby coastal communities. Additionally,
dangerous marine conditions will continue across the adjacent coastal
waters, including the Charleston Harbor.

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

* WIND:
Potential impacts from the main wind event are now unfolding across the
area. Strongest winds are expected to occur mainly east of Interstate 95,
especially near the southeast South Carolina coast along Charleston County.
Remain well sheltered from life-threatening wind having extensive impacts.
If realized, these impacts 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.

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

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
southeast South Carolina, especially across the Tri-County area.
The heaviest rain is expected across coastal portions of Charleston
County and eastern most portions of Berkeley County. Locations near
Downtown Charleston and surrounding coastal communities could see
the greatest impacts. If realized, these impacts include:
    - Extreme rainfall flooding could prompt widespread rescues. As
      event unfolds, rescues could become impossible.
    - Rivers and tributaries could overwhelmingly overflow their
      banks in many places with deep moving water. Small streams,
      creeks, canals, and ditches may become raging rivers with
      strong currents. Flood control systems and barriers could
      become stressed or overwhelmed.
    - Flood waters will enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Flood waters could render escape routes impassable.
      Streets and parking lots become rivers of raging water with
      underpasses submerged. Driving conditions become impossible and
      life threatening. Widespread road and bridge closures with most
      weakened or washed out.
    - Drinking water and sewer services could be negatively impacted.
    - Hazardous containers and materials could possibly be present in
      flood waters.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
coastal southeast South Carolina, especially along the Charleston County.
Remain well away from life-threatening surge having possible extensive
impacts. If realized, these impacts 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.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across northern
Charleston County and northeast portions of Berkeley County. Remain
well braced against a tornado event having possible limited impacts.
If realized, these 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 9 feet or greater, and
strong rip currents will occur at the beaches of Southeast South
Carolina and Southeast Georgia. A High Surf Advisory and a High Risk of
Rip Currents remains in effect for the entire coast.

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

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

* OTHER PREPAREDNESS INFORMATION:
During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.

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.

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.
