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

Hurricane Dorian remains a strong category 2 hurricane with peak
winds of 110 mph and higher gusts. Dorian continues to move slowly to
the north-northwest, and that continues this evening. Tropical storm
winds of at least 39 mph will continue along Atlantic Coastal areas
of southeast Georgia and Northeast Florida. Outer rainbands are capable
of producing torrential rainfall and gusts to around 50 mph.

Dorian will also bring a threat of storm surge flooding, periods of
heavy rainfall, and large battering waves to the coast. Significant to
severe beach erosion will be likely for the beaches. As the winds turn
northwest this evening the high tide cycle pushing down the St Johns
River basin will lead to 2 to 3 ft or storm surge across portions of
Putnam County later this evening.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
the Atlantic Coastal areas of Southeast Georgia and Northeast Florida
including portions of the St Johns River Basin in Putnam county. Remain
well away from life-threatening surge having 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.

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
the Atlantic Coastal areas of Southeast Georgia and Northeast Florida.
Remain well sheltered from dangerous wind having possible 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.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the Atlantic Coastal areas of Southeast Georgia and Northeast Florida.
Remain well guarded against dangerous flood waters having limited 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.

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

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.
