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

Tropical Cyclone Ian will slowly track northward across Florida
through Thursday then approach coastal portions of Georgia and
southern South Carolina later this week. As the storm circulation
approaches and moves inland across Georgia and South Carolina
Thursday into early Saturday, significant impacts from storm surge
inundation, heavy rain, and tropical storm force winds are likely
across the region along with a few tornadoes. The worst conditions
should remain along the coast. The combination of significant storm
surge inundation and heavy rainfall could produce areas of
considerable flooding, especially Friday. In addition, dangerous
marine and surf conditions as well as significant beach erosion are
expected.

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

* SURGE:
Protect against life-threatening surge having possible significant
impacts near and around tidal areas of south coastal South Carolina
and north coastal Georgia. Potential impacts in this area 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.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across southeast South Carolina and southeast
Georgia, especially at the coast. 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.

* WIND:
Protect against dangerous wind having possible significant impacts
across southeast South Carolina and southeast Georgia, especially at
the coast. 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.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges and access routes
      impassable.
    - Travel by vehicle or on foot increasingly difficult. Danger of
      death or injury from falling objects such as trees or electric
      wires outside.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines, which could persist for hours
      or days.
    - Some poorly secured small craft could break loose from their
      moorings.

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

* TORNADOES:
Protect against a tornado event having possible limited impacts
across mainly coastal areas of southeast South Carolina and southeast
Georgia. 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:
Listen to local official for recommended preparedness actions, including
possible evacuation. If ordered to evacuate, do so immediately.

For those not under evacuation orders, assess the risk from wind, falling
trees, and flooding at your location. If you decide to move, relocate to
a safer location nearby. If you do not relocate, help keep roadways open
for those under evacuation orders.

* OTHER PREPAREDNESS INFORMATION:
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.
