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

Hurricane Dorian is beginning to pull away from the northeast
Florida coast tonight, but as it does so, it is strengthening modestly
over the warm Gulf Stream waters, and has reintensified to a Category
3 storm with peak winds of 115 mph. Despite that, observed winds
across northeast Florida have dropped, and sustained winds are below
39 mph, prompting the cancellation of the tropical storm and storm
surge warnings. The warnings continue over the southeast Georgia
coast, where tropical storm force winds and potentially
life-threatening surge can still occur tonight. In the wake of the
storm, outer rainbands passing through the area will be capable of
producing briefly torrential rainfall and gusty winds.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
the beaches of southeast Georgia. Remain well away from life-threatening
surge having additional 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.

Potential impacts from the main surge event are also now unfolding
across the beaches of northeast Florida. Remain well away from locally
hazardous surge having additional limited impacts.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the immediate coast of southeast Georgia. Remain well guarded against dangerous
flood waters having additional limited to significant impacts.
If realized, these impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals, and
      ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some 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 now unfolding across
coastal portions of southeast Georgia and the Atlantic waters. 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.

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

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

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

* OTHER PREPAREDNESS INFORMATION:
Do not be a thrill seeker or risk your life for senseless photos or
videos.

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.
