SITUATION OVERVIEW
------------------

Tropical Storm Ian will move off the eastern coast of Florida
today. Once over the western Atlantic, it is expected to take a turn
toward the north and eventually northwest tonight and strengthen. This
will put Ian on course toward coastal portions of central South
Carolina on Friday as a strong tropical storm or hurricane.

Significant impacts from Ian are expected to begin late tonight and
into Friday morning across the Midlands and CSRA. Heavy rainfall may
lead to flash flooding, particularly Friday and Friday night. Tropical
storm force winds are also expected, particularly across the Midlands
and Pee Dee region. There also a minimal threat for tornadoes, mainly
confined to the far eastern Midlands.

POTENTIAL IMPACTS
-----------------

* WIND:
Protect against dangerous wind having possible significant impacts
across the Midlands of central South Carolina and east central Georgia.
Potential impacts in this area 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. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines.


* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across the Midlands of central South Carolina and
east central Georgia CSRA. Potential impacts include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, arroyos, and
      ditches may become dangerous rivers. In mountain areas,
      destructive runoff may run quickly down valleys while
      increasing susceptibility to rockslides and mudslides. Flood
      control systems and barriers may become stressed.
    - Flood waters can enter many structures within multiple
      communities, some structures becoming uninhabitable or washed
      away. Many places where flood waters may cover escape routes.
      Streets and parking lots become rivers of moving water with
      underpasses submerged. Driving conditions become dangerous.
      Many road and bridge closures with some weakened or washed out.

Prepare for dangerous rainfall flooding having possible significant
impacts across the Midlands of central South Carolina and east
central Georgia CSRA.

* TORNADOES:
Little to no impacts are anticipated at this time across the Midlands
of central South Carolina and east central Georgia CSRA.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

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, consider moving to a safer shelter before the onset of
strong winds or flooding.

Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
