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

Ian has become a hurricane again over the western Atlantic, and was
moving towards the Carolinas. Ian is expected to intensify as it treks
through the Atlantic waters towards the Carolinas tonight and Friday
morning.

A storm surge warning is in effect along the coast as well as the St
Johns River with storm surge inundation up to 6 feet along the coast
and intracoastal waterway, and 2 to 4 feet for the St Johns River.
Trapped tides in the St. Johns river will exacerbate flooding for areas
along the St. Johns river.

Additional rainfall amounts up to 2 inches are possible this evening
before Hurricane Ian moves away from the area.

A hurricane watch is in effect along the coast of northeast FL and
southeast GA, with tropical storm warnings up for portions of
northeast FL and southeast GA. Over the tropical storm warning area,
tropical storm force winds are unfolding over northeast FL and southeast
Georgia. Gusts to hurricane strength will be possible along the coast.

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

* SURGE:
Potential impacts from the main surge event are about to unfold
across coastal southeast Georgia, coastal northeast Florida,
intracoastal waterway, and the St. Johns River basin. Remain well
away from life- threatening surge having possible significant
impacts. If realized, these impacts include:
    - Areas of inundation 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 usually vulnerable low
      spots.
    - Major beach erosion with heavy surf breaching dunes. Strong and
      numerous rip currents.
    - Moderate damage to marinas, docks, boardwalks, and piers.
      Several small craft broken away from moorings, especially in
      unprotected anchorages.

Also, protect against locally hazardous surge having possible limited
impacts across inland Glynn, Nassau, and Camden counties.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
coastal northeast Florida and southeast Georgia. Remain well guarded
against locally hazardous flood waters having additional limited
impacts. If realized, these impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, and ditches may become swollen
      and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across Northeast Florida and Southeast Georgia, little to
no impact is anticipated.

* WIND:
Potential impacts from the main wind event are unfolding across
portions of northeast Florida, north central FL, and southeast
Georgia. Remain well sheltered from dangerous wind having possible
significant impacts. If realized, these impacts 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.

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

* EVACUATIONS:
Do not enter evacuated areas until officials have given the all clear
to return.

* OTHER PREPAREDNESS INFORMATION:
If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.
