SITUATION OVERVIEW
------------------
Hurricane Dorian remains a dangerous hurricane. Dorian is forecast
to continue north, then north-northeast as it passes near the South
Carolina coast this morning 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
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 additional 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
southeastern 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. Remain well guarded against life-threatening flood waters
having possible devastating 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 southeastern South Carolina. 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:
Little to no impacts are anticipated at this time
across southeast South Carolina and southeast Georgia.
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.
