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

There are no major changes to the previous forecast. The center of
Hurricane Dorian remains nearly stationary just to the north of Grand
Bahama this morning. While the center of Dorian is still forecast to
remain offshore, periods of tropical storm force winds with higher
gusts are expected over Palm Beach County through tonight, with the
greatest chances over the northeastern portion of the county.
Occasional tropical storm force wind gusts from squalls are possible
over the rest of South Florida through this evening.

The threat of life-threatening storm surge exists along the Palm Beach
County coast over the next couple of days, where a storm surge of 3 to
5 feet above ground level is expected along 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. This surge includes the
effects from some of the wave action from extremely high waves over
the offshore Atlantic waters. Coastal Broward County could experience
storm surge of 1 to 3 feet above ground level, while coastal
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
next several days.

A few tornadoes are also possible over the next day or so, with the
greatest potential along and near the east coast.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
northeastern and coastal Palm Beach County. Present indications are
that sustained winds of 30 to 45 mph with gusts between 50 and 60 mph
are expected today. These winds are expected to be common from 8 AM to
6 PM EDT today, with the most-likely time for strongest winds from noon
to 4 PM EDT. 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.
    - Large areas with power and communications outages.

Potential impacts from the main wind event are also now unfolding
across the rest of 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 Southeast 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.

* 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:
    - 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.

* TORNADOES:
Potential impacts from tornadoes are still unfolding across Southeast
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.

Elsewhere across South Florida, 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:
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.
