SITUATION OVERVIEW
------------------
Tropical Storm Michael is expected to gradually weaken as it tracks
northeastward across Georgia and South Carolina today. The main
hazards this morning across Southeast South Carolina and Southeast
Georgia will include isolated to scattered tornadoes, tropical storm
force winds, heavy rainfall resulting in isolated freshwater flooding,
dangerous surf conditions and coastal flooding. Conditions will
improve this afternoon as Michael accelerates away from the area.
POTENTIAL IMPACTS
-----------------
* TORNADOES:
Potential impacts from tornadoes are still unfolding across southeast
South Carolina and southeast Georgia. 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.
* WIND:
Potential impacts from the main wind event are now unfolding across
southeast South Carolina and southeast Georgia. Remain well sheltered
from dangerous wind having possible significant impacts. If realized,
these impacts include:
- Some damage to roofing and siding materials, along with damage
to porches, awnings, carports, and sheds. A few buildings
experiencing window, door, and garage door failures. Mobile
homes damaged, especially if unanchored. Unsecured lightweight
objects become dangerous projectiles.
- Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. A few bridges and access routes
impassable.
- Travel by vehicle or on foot increasingly difficult. Danger of
death or injury from falling objects such as trees or electric
wires outside.
- Scattered power and communications outages, but more prevalent
in areas with above ground lines, which could persist for hours
or days.
- Some poorly secured small craft could break loose from their
moorings.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
southeast South Carolina and southeast Georgia, mainly inland. Remain
well guarded against dangerous flood waters having possible significant
impacts. If realized, these 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.
* OTHER COASTAL HAZARDS:
Life-threatening rip currents and very rough surf are expected at area
beaches. Some beach erosion is anticipated.
* SURGE:
Potential impacts from the main surge event are now unfolding across
low-lying coastal areas of Southeast South Carolina and Southeast
Georgia. Some beach erosion is anticipated. Remain well away from locally
hazardous surge having possible limited impacts. If realized, these
impacts 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery-powered radio, charged cell phone and flashlight handy.
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 a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
