SITUATION OVERVIEW
------------------
Tropical Storm Helene is expected to strengthen into a major
hurricane as it moves northward across the eastern Gulf of Mexico by
Thursday. The storm is forecast to make landfall around the Big Bend
area of Florida Thursday evening, tracking northward across Georgia
Thursday night into early Friday. Helene is forecast to become a very
large storm, with impacts expected to extend well east of the center
of the storm.
Rainfall amounts across southeast Georgia are forecast to range between
3 to 5 inches and 1.5 to 4 inches across southeast South Carolina.
Isolated higher amounts are possible, especially west of the Interstate
95 corridor. Rainfall rates will increase through Thursday, with the
heaviest rain band sweeping across the region Thursday night into early
Friday morning.
Tropical storm force winds are forecast to increase across southeast
Georgia and the adjacent Atlantic Georgia waters Thursday evening, then
spreading into southeast South Carolina and the adjacent coastal waters
Thursday night. Winds speeds are expected to peak late Thursday night
as the center of Helene moves across central Georgia. In addition, rain
bands are expected to rapidly lift north across southeast Georgia and
the South Carolina Lowcountry Thursday night. These rain bands should
produce periods of gusty winds and possibly spawning some tornadoes.
Storm surge inundation of 1 to 3 ft is possible along the coast of
southeast Georgia and the South Carolina Lowcountry.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for hazardous wind having possible limited impacts across
southeast South Carolina and southeast Georgia. Potential impacts
include:
- Damage to porches, awnings, carports, sheds, and unanchored
mobile homes. Unsecured lightweight objects blown about.
- Large tree limbs broken off. A few trees snapped or uprooted,
but with greater numbers in places where trees are shallow
rooted.
- Some roads impassable due to debris, particularly within urban
or heavily wooded locations. Hazardous driving conditions on
bridges and other elevated roadways, especially for high
profile vehicles.
- Isolated to scattered power and communications outages.
* TORNADOES:
Prepare for a particularly dangerous tornado event having possible
extensive impacts across southeast Georgia and southeast South Carolina.
Potential impacts include:
- Numerous tornadoes can greatly hinder the execution of
emergency plans.
- Tornadoes could produce pockets of extensive destruction, power
loss, and communications failures. In some locations, tornado
winds and deadly projectiles demolish sturdy buildings, sweep
away structures upon weak foundations, obliterate mobile homes,
snap off and uproot large trees, lift vehicles off the ground
and throw with distance, and destroy small boats destroyed.
Prepare for a dangerous tornado event having possible significant
impacts across coastal Georgia.
* SURGE:
Prepare for locally hazardous surge having possible limited impacts
across southeast South Carolina and southeast Georgia. Potential
impacts in this area include:
- Localized inundation of saltwater mainly along immediate
shorelines and in low-lying spots farther inland near rivers
and creeks.
- Sections of near-shore roads and parking lots become overspread
with surge water. Driving conditions hazardous in places where
surge water covers the road.
- Minor to moderate beach erosion. Heavy surf possibly breaching
dunes, mainly in normally vulnerable locations. Strong rip
currents.
- Minor to locally moderate damage to marinas, docks, boardwalks,
and piers. A few small craft broken away from moorings.
Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across southeast South Carolina and southeast Georgia.
Potential impacts include:
- Moderate rainfall flooding could prompt some rescues.
- Rivers and tributaries could quickly become swollen with
swifter currents and overspill their banks in a few places,
especially in normally vulnerable spots. Small streams, creeks,
canals, and ditches overflow.
- Flood waters can enter some structures or weaken foundations.
Several places could experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
become hazardous. Some road and bridge closures.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.
