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

Hurricane Ian is in the western Atlantic. Ian will be moving
northward overnight. This will put Ian on course toward the
north-central coastal portions of South Carolina on Friday.

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.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across the the eastern Midlands and Pee Dee of South
Carolina.
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.

Protect against dangerous rainfall flooding having possible limited
to significant impacts across the Western Midlands of central South
Carolina and east central Georgia CSRA.

* WIND:
Protect against life-threatening wind having possible extensive
impacts across the eastern Midlands and Pee Dee of South Carolina.
Potential impacts in this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Also, protect against dangerous wind having possible limited to
significant impacts across the Western 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.
