SITUATION OVERVIEW
------------------
Ian was moving north over the Atlantic waters off of the Southeast
coast and will make landfall over South Carolina as a hurricane later
today before rapidly weakening as it heads northwest through the
Carolinas toward the mountains. The greatest impacts will last today
into tonight, increasing gusty winds expected to reach
tropical-storm-force with mainly hurricane force gusts. 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 tonight, but coastal flooding
issues may linger a little longer.

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

* WIND:
Prepare for life-threatening wind having possible extensive impacts
across northeast South Carolina and southeast North 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 northeast South Carolina and
southeast North Carolina.

* SURGE:
Protect against life-threatening surge having possible extensive
impacts across coastal South Carolina and 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, protect against life-threatening surge having possible
significant impacts across the lower Cape Fear River in inland New
Hanover.

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across northeastern 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.

Protect against dangerous rainfall flooding having possible
significant impacts across southeastern North Carolina.

* TORNADOES:
Protect against 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

forecast.
