SITUATION OVERVIEW
------------------
Major Hurricane Dorian will continue to move very slowly west across
the northern Bahamas and then turn northwest just off the Florida east
coast by early Tuesday. Dorian is forecast to parallel the coastline
Tuesday into Wednesday.
Listen to local officials and heed evacuation orders as given. Large
battering waves and higher than normal tides will add to the
destructive potential, along with beach erosion.
Heavy rainfall is forecast over east central Florida with total
accumulations of 3 to 6 inches with maximum isolated rainfall amounts
to 9 inches along the east coast. Flash flooding is possible,
especially in urban and poorly drained areas.
POTENTIAL IMPACTS
-----------------
* SURGE:
Prepare for life-threatening surge having possible extensive impacts
across the beaches of northeast Florida and into the mouth of the
St Johns River. Potential impacts in this area include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.
* WIND:
Prepare for life-threatening wind having possible extensive impacts
across coastal northeast Florida including Flagler, St Johns, coastal
Duval and coastal Nassau Counties. 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, prepare for dangerous wind having possible limited to
significant impacts across inland Nassau, inland Duval, Clay, Putnam
and eastern Marion Counties.
* FLOODING RAIN:
Prepare for locally hazardous rainfall flooding having possible
limited impacts across Flagler, St Johns, Duval and Nassau Counties.
Potential impacts include:
- Localized rainfall flooding may prompt a few evacuations.
- Rivers and tributaries may quickly rise with swifter currents.
Small streams, creeks, canals, and ditches may become swollen
and overflow in spots.
- 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.
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 check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.
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, plan to move to safe shelter.
If you live in a place particularly vulnerable to flooding, such as
near the ocean or a large inland lake, in a low-lying or poor
drainage area, in a valley, or near an already swollen river, plan to
move to safe shelter on higher ground.
Always heed the advice of local officials and comply with orders that
are issued. Do not needlessly jeopardize your life or the lives of
others.
When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.
Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.
