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

Hurricane Ian is expected to approach north coastal Georgia and
south coastal South Carolina as a hurricane, making landfall on
Friday. The risk for impacts will increase tonight and continue
through at least Friday with life-threatening storm surge inundation,
flooding rains, isolated tornadoes and tropical storm force winds
likely as the storm approaches the area. Wind gusts to hurricane force
are also possible, mainly along the immediate coast and around
Charleston Harbor, especially Friday morning. The combination of
life-threatening storm surge inundation and heavy rainfall could
produce areas of considerable urban and flash flooding, especially
Friday. In addition, dangerous marine and surf conditions will
continue with significant beach and lakeshore erosion becoming more
likely at the beaches and around Lake Moultrie.

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

* SURGE:
Prepare for life-threatening surge having possible extensive impacts
near and around tidal areas of south coastal South Carolina
and north coastal Georgia. Potential impacts in this area
include:
    - Large areas of deep inundation of saltwater along immediate
      shorelines and in low-lying spots farther inland near rivers
      and creeks, with storm surge flooding accentuated by battering
      waves. Structural damage to buildings, with several washing
      away. Damage compounded by floating debris. Locations may be
      uninhabitable for an extended period.
    - Large sections of near-shore escape routes and secondary roads
      washed out or flooded and impassable. Flood control systems and
      barriers could become stressed.
    - Severe beach erosion with significant dune loss.
    - Major damage to marinas, docks, boardwalks, and piers. Many
      small craft broken away from moorings, especially in
      unprotected anchorages, with some lifted onshore and stranded.
    - Drinking water and sewer services negatively impacted.
    - Hazardous containers and materials possibly present in surge
      waters.

Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.

* WIND:
Prepare for life-threatening wind having possible extensive impacts
across across Southeast South Carolina and Southeast Georgia, especially at
the coast. Potential impacts in this area include:
    - Considerable roof damage to sturdy buildings, with some window,
      door, and garage door failures leading to structural damage.
      Mobile homes severely damaged, with some destroyed. Damage
      accentuated by airborne projectiles. Some locations may be
      uninhabitable for weeks.
    - Danger of death or injury from falling objects and airborne
      projectiles outside.
    - Large trees snapped or uprooted.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded locations. Several bridges and access routes
      impassable.
    - Large areas with power and communications outages, which could
      persist for days.
    - Several secured small craft could break free from moorings.

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts, especially across South Carolina and Chatham County,
Georgia. Potential impacts include:
    - Major rainfall flooding could prompt many rescues.
    - Rivers and tributaries could rapidly overflow their banks in
      multiple locations. Small streams, creeks, canals, ditches may
      become dangerous rivers. Flood control systems and barriers
      could become stressed.
    - Flood waters could enter many structures within multiple
      communities; some structures become uninhabitable or are washed
      away. Flood waters could cover multiple 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.
    - Drinking water and sewer services could be negatively impacted.
    - Hazardous containers and materials could possibly be present in
      flood waters.

* OTHER COASTAL HAZARDS:
Life-threatening surf conditions, including dangerous rip currents, high
waves, as well as beach and lakeshore erosion are expected across coastal
portions of Southeast South Carolina and Southeast Georgia, including
Lake Moultrie.

* TORNADOES:
Prepare for a tornado event having possible limited impacts across parts
of Charleston County, especially near the coast. Potential 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.

Elsewhere across southeast South Carolina and southeast Georgia,
little to no impact is anticipated.

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

* EVACUATIONS:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.

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 near an already swollen river, plan to
move to safe shelter on higher ground.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.

Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!

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.
