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

Extremely dangerous Hurricane Dorian, a Category 5 system, is over
Grand Bahama this morning. Dorian should move closer to the Florida
east coast later today into Tuesday. While the center of Dorian is
forecast to remain offshore of southeast Florida, periods of tropical
storm force winds are expected over Palm Beach County from this
morning into Tuesday night, with the greatest chances over the eastern
portion of the county. Also, there is a reasonable risk of hurricane
force winds in coastal and metro Palm Beach County between tonight and
Tuesday evening. A reasonable risk of tropical storm force winds also
continues for eastern Broward and Glades Counties, as well as Lake
Okeechobee, with occasional tropical storm force wind gusts possible
for all areas today into Tuesday night.

The threat of life-threatening storm surge exists along the Palm Beach
County coast today 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 Lake Worth. South of Lake Worth to Boca
Raton, a storm surge of 2 to 4 feet above ground level is possible.
These surge values are based on either the storm tracking a little
closer to the coast, or due to wave action. Coastal sections of
Broward County could also experience storm surge of 1 to 2 feet above
ground level today through the middle of this week.

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. 

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 afternoon.

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

* WIND:
Protect against life-threatening wind having possible extensive 
impacts across 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 limited to 
significant impacts over areas from Lake Okeechobee into metro and 
coastal Broward County and possible limited impacts across the 
remainder of South Florida. 

* SURGE:
Protect against life-threatening surge having possible significant
impacts across coastal Palm Beach County, with the greatest risk from
Lake Worth northward. 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.

* 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. 

* TORNADOES:
Protect against a tornado event having possible limited impacts across
South Florida. Potential 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.

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, follow designated evacuation routes. Seek traffic 
information on roadway signs, the radio, and from official sources.

* 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.

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 a Tornado Warning is issued for your area, be ready to shelter 
quickly, preferably away from windows and in an interior room not 
prone to flooding. If driving, scan the roadside for quick shelter 
options.

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.
