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

Hurricane Dorian is a powerful and dangerous Category 5 major
hurricane moving over the northern Bahamas today, before moving closer
to the Florida east coast late Monday through Tuesday night. Although
the latest forecast keeps the center of Dorian offshore of the
Southeast Florida coast, periods of tropical storm force winds are
expected over parts of coastal and metro Palm Beach County from early
Monday morning into early Wednesday morning. There is also a
reasonable risk of hurricane force winds in Palm Beach County Monday
night through Tuesday evening, with the highest chances in the eastern
portions of Palm Beach County. A reasonable risk of tropical storm
force winds also continues over other portions of South Florida Monday
through late Tuesday night, with higher chances over Broward County as
well as inland portions of Palm Beach County and Glades County. Over
the remainder of South Florida, occasional tropical storm force wind
gusts are expected Monday and Tuesday.

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. Preparations
should continue in the watch and warning areas, and please follow the
advice of local officials, including any evacuation orders. The
potential of life-threatening storm surge exists along the Palm Beach
County coast Monday through the middle of the week, where a storm
surge of 2 to 4 foot above ground level is possible if the storm were
to track closer to South Florida. Coastal sections of Broward County
could also experience storm surge of 1 to 2 foot above ground level
Monday through the middle of the week.

Regardless of the eventual track of Dorian, major 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 as far south as the Miami-Dade County 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 portions of metro and 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 significant
impacts over areas from Lake Okeechobee into Broward County and
possible limited impacts across the remainder of South Florida.

* SURGE:
Protect against life-threatening surge having possible significant
impacts across portions of coastal Palm Beach County. Potential impacts in
this area 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 other portions of South Florida's Atlantic coast.

Elsewhere across South Florida, little to no impact is anticipated.

* FLOODING RAIN:
Protect against locally hazardous rainfall flooding having possible
limited impacts across South Florida. Potential impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Ditches and canals may quickly rise with swift currents.
    - 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.

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

* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.

For those not under evacuation orders, assess the risk from wind,
falling trees, and flooding at your location. If you decide to move,
relocate to a safer location nearby. If you do not relocate, help keep
roadways open for those under evacuation orders.

If evacuating, leave with a destination in mind and allow extra time
to get there. Take your emergency supplies kit. Gas up your vehicle
ahead of time.

Let others know where you are going prior to departure. Secure loose
items and pets in the car, and avoid distracted driving.

* 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 or parish in which
it resides. Listen for these locations in local news updates. Pay
attention for instructions from local authorities.

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the 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.
