SITUATION OVERVIEW
------------------
Extremely dangerous Hurricane Florence continues to approach the
Southeast U.S. coast as a major hurricane. The latest forecast brings
the center of Florence close to the southeast North Carolina coast
Friday, then Florence could stall then drift west or southwest this
weekend. Regardless of the exact path, impacts will extend well away
from the center and into southeast South Carolina. The track could
shift slightly farther south and west. If this occurs, the region
within the Hurricane Watch and Storm Surge Watch area could experience
life-threatening storm surge inundation, damaging winds and excessive
rainfall. This includes areas between Edisto Beach and South Santee
River, including Berkeley County, Dangerous surf zone conditions will
also continue on the beaches of southeast South Carolina and southeast
Georgia at least through late week. The worst conditions are expected
Thursday night into at least Saturday, although impacts could linger
longer depending on the uncertain evolution and track of Florence
beyond Friday.
POTENTIAL IMPACTS
-----------------
* SURGE:
Prepare for life-threatening surge having possible significant
impacts across Charleston and Tidal Berkeley Counties. Potential impacts
in this area include:
- Areas of inundation of saltwater along immediate shorelines and
in low-lying spots farther inland near rivers and creeks, with
storm surge flooding accentuated by waves. Damage to several
buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in normally vulnerable low
spots.
- Moderate to major beach erosion with heavy surf breaching
dunes. Strong and numerous rip currents.
- Minor to moderate damage to marinas, docks, boardwalks, and
piers. Several small craft broken away from moorings,
especially in unprotected anchorages. Some navigation aids
possibly displaced well off station, creating difficult
navigation near inlets and waterways.
Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.
* WIND:
Prepare for life-threatening wind having possible extensive impacts
near South Santee River in South Carolina. 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 the rest of southeast South Carolina.
* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible
limited impacts along and east of Interstate 26. Potential
impacts include:
- Localized rainfall flooding could prompt a few rescues.If in a place
that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, plan to move to safe shelter.
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 If in a place
that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, plan to move to safe shelter.
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.
Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.
When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.
Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.
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.

- Rivers and tributaries could quickly rise with swifter
currents. Small streams, creeks, canals, and ditches could
become swollen and overflow in spots.
- Flood waters can enter a few structures, especially in normally
vulnerable spots. Rapid ponding of water could occur at
underpasses, low-lying spots, and poor drainage areas. Several
storm drains and retention ponds become near-full and begin to
overflow. Some brief road and bridge closures.
Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.
* OTHER COASTAL HAZARDS:
A high risk for rip currents exists on all areas beaches today and will
likely continue through at least late week. Also, the Wednesday morning
high tide could top out around 7.0 feet mean lower low water on
Charleston Harbor, resulting in minor salt water flooding. Minor coastal
flooding could also occur along the South Carolina coast, especially
south of Edisto beach, around the time of each high this week. Elevated
surf and tides could also produce beach erosion this week.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
If evacuating, leave with a destination in mind and allow extra time
to get there. Take your emergency supplies kit. Gas up your vehicle
ahead of time.

kit and take necessary actions to protect your family and secure your
home or business.
