SITUATION OVERVIEW
------------------
Hurricane Dorian remains a very dangerous hurricane. Dorian is
forecast to continue north northwestward just off the east coast of
Georgia, then turn north and eventually northeast as it passes near
the South Carolina coast tonight through Thursday. Hazardous
conditions will overspread the area including damaging winds, life-
threatening storm surge inundation, flash flooding, strong rip
currents, and severe beach erosion. Additionally, dangerous marine
conditions will occur across the adjacent coastal waters, including
the Charleston Harbor. The combination of significant storm surge
inundation and heavy rainfall will enhance the risk for flash
flooding, especially along the coast, including Downtown Charleston
and portions of the Savannah Metro Area, and the nearby coastal
communities.
POTENTIAL IMPACTS
-----------------
* SURGE:
Potential impacts from the main surge event are now unfolding across
the coastal counties of Southeast South Carolina and Southeast Georgia.
Remain well away from life-threatening surge having 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.
* WIND:
Potential impacts from the main wind event are now unfolding across the area.
The strongest winds are expected to occur mainly east of Interstate 95, especially
near the Southeast South Carolina coast. Tropical storm force winds will extend
across interior portions. 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.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across the area.
The heaviest rain is expected across coastal portions of Southeast South
Carolina and Southeast Georgia, especially in Charleston County. Remain
well guarded against life-threatening flood waters having extensive 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.
* TORNADOES:
Potential impacts from tornadoes are still unfolding east of Interstate 95
in Southeast South Carolina. 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.
If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
