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

Hurricane Dorian is a powerful and dangerous Category 4 major
hurricane which is forecast to be moving over the northern Bahamas
today, before nearing the Florida east coast late Monday through
Tuesday. Although the latest forecast keeps the center of Dorian
offshore of the Southeast Florida coast, there is still a reasonable
risk of tropical storm force winds across portions of South Florida,
with the highest chances in eastern portions of Palm Beach and Broward
Counties.

Due to Dorian's close proximity to the Florida east coast, small
shifts in the track of the hurricane would bring substantial changes
in expected impacts. Residents and visitors in South Florida should
continue to monitor the progress of Hurricane Dorian.

Regardless of the eventual track of Dorian, significant marine and
beach impacts are expected along the entire Southeast Florida coast. A
prolonged period of strong winds over the Atlantic coastal waters will
cause very hazardous seas, rough surf, and beach erosion through the
middle of the week. Coastal flooding is also possible in vulnerable
locations along the east coast each day through the middle of the
week, particularly during the times of high tide.

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

* WIND:
Protect against life-threatening wind having possible extensive impacts
across northern portions of coastal Palm Beach County. Potential
impacts in this area include:
    - Considerable roof damage to sturdy buildings, with some having
      window, door, and garage door failures leading to structural
      damage. Mobile homes severely damaged, with some destroyed.
      Damage accentuated by airborne projectiles. Locations may be
      uninhabitable for weeks.
    - Many large trees snapped or uprooted along with fences and
      roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. Several bridges, causeways, and
      access routes impassable.
    - Large areas with power and communications outages.

Also, protect against dangerous wind having possible limited to
significant impacts elsewhere across southeastern Florida, especially
in Palm Beach County and across metro and coastal Broward County.

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across South Florida. Potential impacts include:
    - 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.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across coastal Palm Beach County. Additional details regarding the
potential for coastal inundation are addressed in the Coastal Flood
Statement. Potential impacts in this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low-lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near-shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Major beach erosion. Heavy surf also breaching dunes, mainly in
      usually vulnerable locations. Strong rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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

* OTHER PREPAREDNESS INFORMATION:
Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Ensure you are in a
safe location before the onset of strong winds or possible flooding.

It is important to remain calm, informed, and focused during an
emergency. Be patient and helpful with those you encounter.

If you are a visitor, be sure to know the name of the city or town in
which you are staying and the name of the county in which it resides.
Listen for these locations in local news updates. Pay attention for
instructions from local authorities.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured home, upper floors of a high-rise building, or
on a boat, consider moving to a safer shelter before the onset of
strong winds or flooding.

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.
