SITUATION OVERVIEW
------------------
Tropical Storm Ian is now exiting the east-central Florida coast,
beginning its movement toward the Carolinas. The greatest impacts will
be late tonight through Friday night, with gusty winds increasing
through Friday, and expected to reach tropical-storm- force. There is
potential for hurricane force winds as well, mainly near the coast of
South Carolina. Confidence is increasing on more widespread impacts
from wind and storm surge inundation, especially along the northeast
South Carolina coast. Heavy rain, coastal flooding, and beach erosion
are also expected. Rain tapers off by early Saturday morning, but
coastal flooding issues may linger a little longer.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for life-threatening wind having possible extensive impacts
across coastal South Carolina. Potential impacts in this area
include:
- Some structural damage is likely, with buildings receiving roof
damage as well as window, door, and garage door failures.
Mobile homes potentially suffering severe damage, with some
destroyed. Damage may be enhanced by projectiles. Locations may
be inaccessible or uninhabitable for some time after the storm
passes.
- Widespread large limbs will be down and many trees snapped or
uprooted, along with fences and roadway signs blown over.
- Roads will be blocked in many areas as a result of large
debris, especially within urban or heavily wooded areas.
Several bridges, causeways, and elevated roadways will likely
become unsafe.
- Widespread areas will suffer from power and communication
outages.
- Several poorly secured small craft may break from their
moorings.
Also, prepare for dangerous wind having possible limited to
significant impacts across inland northeast South Carolina and
southeast North Carolina.
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across northeast South Carolina. Potential
impacts include:
- Major flooding from rainfall may prompt evacuations and
numerous rescues.
- Rivers and streams may rapidly overflow their banks in multiple
places. Creeks and ditches will flood and may contain strong
currents.
- Flood waters may enter many structures, and some may become
uninhabitable. Some road scours or complete road failures will
be possible, along with the potential for sinkholes. Many
streets and parking lots may flood, and may be impacted by
flowing water. Many road and low-lying bridge closures are
possible with some weakened or washed away. Driving conditions
will be dangerous.The delivery of drinking water and sewer
services may be interrupted. Flood waters may be polluted and
contain hazardous materials.
Prepare for dangerous rainfall flooding having possible significant
impacts across southeast North Carolina.
* SURGE:
Prepare for life-threatening surge having possible extensive impacts
across coastal South Carolina and Brunswick County in coastal
southeastern North Carolina. 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.
Also, prepare for life-threatening surge having possible significant
impacts along the lower Cape Fear River.
Also, prepare for locally hazardous surge having possible limited
impacts across coastal New Hanover and Pender County in southeast
North Carolina.
Elsewhere across southeast North Carolina and northeast South
Carolina, little to no impact is anticipated.
* 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
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and take necessary
actions to secure your home or business. Deliberate efforts should be
underway to protect life and property. Ensure that your Emergency
Supplies Kit is stocked and ready.
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 canyon, or near an already swollen
river, plan to move to safe shelter on higher ground
Be sure to let friends and other family members know of your
intentions and whereabouts for surviving the storm. For emergency
purposes, have someone located away from the threatened area serve as
your point of contact. Share vital contact information with others.
