SITUATION OVERVIEW
------------------
Bands of heavy rainfall from Tropical Storm Irma will continue to
cross the area this evening, producing the threat for heavy rainfall,
gusty winds, and tornadoes. The life-threatening storm surge
inundation that occurred along the coast this afternoon will continue
to slowly recede through early this evening, though additional
inundation is possible with the early Tuesday morning high tide.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
most of the area, especially along and north of I-16. Remain well
guarded against dangerous flood waters having additional 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.
* WIND:
Potential impacts from the main wind event are now unfolding across
southeast South Carolina and southeast Georgia. Remain well sheltered
from hazardous wind having additional limited impacts. If realized,
these 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:
Potential impacts from tornadoes are still unfolding across southeast
South Carolina. Remain well braced against a tornado event having
additional 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.
* SURGE:
Potential impacts from the main surge event are now unfolding across
low-lying areas along the coast. Remain well away from life-threatening
surge having additional significant impacts. If realized, these impacts
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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Do not return to evacuated areas due to hazardous conditions.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay
inside and away from windows. Listen for updates and be ready in case
you lose electrical power. Locate your battery powered radio and
flashlight from your Emergency Supplies Kit. Keep these items close.
Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.
