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

Extremely dangerous major Hurricane Dorian is over Grand Bahama
this afternoon. Dorian should move closer to the Florida east coast
going into Tuesday. While the center of Dorian is still forecast to
remain offshore of southeast Florida, periods of tropical storm force
winds are expected over Palm Beach County through Tuesday night, with
the greatest chances over the northeastern portion of the county.
Also, some gusts to hurricane force are possible in eastern Palm Beach
County through Tuesday. Occasional tropical storm force wind gusts from
squalls are possible over the rest of South Florida through Tuesday
evening.

The threat of life-threatening storm surge exists along the Palm Beach
County coast through the middle of this week, where a storm surge of
3 to 5 feet above ground level is expected somewhere within surge
prone locations north of Lantana. South of Lantana to Boca Raton, a
storm surge of 2 to 4 feet above ground level is possible. These surge
values are based on wave action from extremely high waves over the
offshore Atlantic waters. Coastal sections of Broward County could
also experience storm surge of 1 to 3 feet above ground level today
through the middle of this week while coastal sections of Miami-Dade
County could experience a storm surge of 2 feet or less above ground
level.

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

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 this week, particularly during the times of high tide.

Tornadoes are also possible, particularly across eastern and southern
portions of South Florida through this evening and possibly into the
overnight.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
portions of coastal Palm Beach County. Remain well sheltered from life-
threatening wind having possible extensive impacts. If realized, these
impacts include:
    - 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.
    - Some areas with power and communications outages.

Potential impacts from the main wind event are also now unfolding
across South Florida. Remain well sheltered from dangerous wind having
possible limited to significant impacts.

* SURGE:
Potential impacts from the main surge event are now unfolding across
the Atlantic coast of South Florida. 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.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across South
Florida. Remain well braced against a tornado event having possible
limited impacts. If realized, these impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, mobile
      homes pushed off foundations or overturned, large tree tops and
      branches snapped off, shallow-rooted trees knocked over, moving
      vehicles blown off roads, and small boats pulled from moorings.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
South Florida. Remain well guarded against locally hazardous flood
waters having possible limited impacts. If realized, these impacts
include:
    - 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:
Do not enter evacuated areas until officials have given the all clear
to return.

* OTHER PREPAREDNESS INFORMATION:
Keep your cell phone charged and in power-saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and check-
ins.

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.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
