SITUATION OVERVIEW
------------------
Hurricane Dorian remains a strong hurricane as it tracks slowly
north off the coast of southern South Carolina. Dorian will turn
to the northeast later this afternoon, and will pass very close to Cape
Fear tonight. The risk of hazardous conditions will increase
across the region, including damaging winds, life-threatening storm
surge inundation, flash flooding, strong rip currents, and severe
beach erosion. Additionally, dangerous marine conditions are
expected to occur across the adjacent coastal waters. Heavy rainfall
will enhance the risk for flash flooding.
POTENTIAL IMPACTS
-----------------
* SURGE:
Prepare for life-threatening surge having possible extensive impacts
across coastal areas including low lying areas along Winyah
Bay, area beaches, and other areas along the Intracoastal Waterway.
Potential impacts in this area include:
- Large areas of deep inundation with storm surge flooding
enhanced by battering waves. Structural damage to buildings is
likely, with several potentially washing away. Damage will be
compounded by floating debris. Some locations may become
uninhabitable for an extended period.
- Inundation is likely to impact vulnerable homes along tidal
creeks and waterways farther inland.
- Drinking water and sewer services will likely become impacted
by the storm surge. Surge waters will contain hazardous
materials.
- Large sections of coastal roads will become flooded, or
wash-out altogether.
- Severe beach erosion is expected with significant dune loss.
Sands from displaced dunes will likely deposit onto the barrier
island roads.
- Major damage to marinas, docks, boardwalks, and piers is
possible. Many small craft broken away from moorings,
especially in unprotected anchorages with some lifted onshore
and stranded inland.
- Navigation may be difficult, especially near inlets and
waterways, as some navigational aids may be off station or
missing. Debris is possible in the waterways and other
navigable channels.
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across coastal Horry and Georgetown counties, including
the Grand Strand of Myrtle Beach. Potential impacts include:
- Extreme flooding from rainfall may prompt numerous evacuations
and rescues.
- Rivers and streams may overwhelmingly overflow their banks with
deep moving water. Creeks and ditches will become severely
flooded and contain strong currents.
- Flood waters may enter numerous structures, and some may become
uninhabitable or washed away. Road scours or complete road
failure is likely in many locations, along with the potential
for sinkholes. Many streets and parking lots will flood, and
may be impacted by swift, flowing water. Numerous road and
low-lying bridge closures are likely with some weakened or
washed away. Driving conditions will be very dangerous.
- The delivery of drinking water and sewer services may be
interrupted. Flood waters may be polluted and contain hazardous
materials.
Protect against life-threatening rainfall flooding having possible
significant to extensive impacts across inland counties along and east of
the I-95 corridor.
* WIND:
Protect against life-threatening wind having possible extensive
impacts across counties that border the coast, especially beaches and
communities along the ocean front. Potential impacts in this area include:
- Structural damage can be expected to sturdy buildings, with
some suffering severe or total destruction. Complete
destruction of mobile homes and other poorly constructed
buildings is likely. Damage greatly enhanced by large
projectiles. Locations may be uninhabitable for a significant
period of time.
- Numerous large trees may be snapped or uprooted, along with
fences and roadway signs gone.
- Many roads will become unsafe and impassable from large debris.
Many bridges, causeways, and other elevated roadways will
become impassable.
- Extensive power and communications outages can be expected.
- Many vessels will break free from their moorings.
Also, protect against dangerous wind having possible limited to
significant impacts across inland counties east of the I-95 corridor.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across
southeast North Carolina and northeast South Carolina. Potential
impacts include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Tornadoes can cause damage to trees, vehicles, boats, and
buildings. Unsecured mobile homes and poorly constructed
structures are particularly vulnerable.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
For those under evacuation orders, leave as soon as practical with a
destination in mind. Gas up your vehicle well ahead of time. Be sure
that you take all essential materials from your emergency supplies kit.
Let others know where you are going and when you intend to arrive.
For those not under evacuation orders, understand that there are
inherent risks to evacuation (such as traffic congestion, accidents,
and driving in bad weather), so evacuate only if necessary. Help keep
roadways open for those that are under evacuation orders.
If evacuating away from the area or relocating to a nearby shelter, leave
early before weather conditions become hazardous.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Failure to adequately shelter may result in serious injury or loss of
life. Always heed the advice of local officials and comply with any
orders that are issued. Remember, during the storm 9 1 1 Emergency
Services may not be able to immediately respond if conditions are
unsafe. This should be a big factor in your decision making.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.
If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.
