SITUATION OVERVIEW
------------------
Hurricane Florence has intensified into a major Category 4 Hurricane,
and is expected to make landfall as a major Hurricane in the Carolinas
early Friday morning. There is still some uncertainty regarding the
exact forecast track, but significant to potentially life threatening
impacts are expected across Eastern North Carolina. A slight shift in
the track could change impacts drastically.
Extreme life threatening storm surge impacts are expected with
Hurricane Florence. Based on the current forecast, inundation of 6 to
12 feet above ground level will be possible near and to the east of the
eye across the southern North Carolina coast...including the Pamlico
Sound, and tidal portions of rivers and streams. Significant storm
surge flooding is expected over the northeastern North Carolina coast
with inundation of 4 to 8 feet above ground. A small shift in the track
could change what locations may see the most significant inundation.
Very high surf and large breaking waves will likely result in
significant beach erosion and ocean overwash along the North Carolina
coast Thursday and Friday.
Hurricane force winds in excess of 74 mph are expected to develop
Thursday afternoon across southern portion of Eastern North Carolina.
The strongest winds are expected Thursday night into Friday morning .
Extreme winds in excess of 100 mph are likely along the eyewall where
the storm makes landfall. Tropical storm force winds of 40 mph could
develop as early as Wednesday night. These strong winds will have the
ability to knock down trees, weak structures, and cause widespread
power outages.
Another life threatening concern as Hurricane Florence makes landfall
will be very heavy rainfall leading to the risk for major flooding
across Eastern North Carolina. The current rainfall forecast indicates
widespread amounts of 15 to 20 inches with locally higher amounts up to
30 inches possible. These rainfall totals are likely to cause major
flooding of low lying and urban areas. Flash Flooding is likely to
occur Thursday into Saturday, and river flooding from heavy rainfall
inland will persist for several days to weeks after the storm. The axis
of heaviest rainfall will vary with changes to the forecast track and
storm motion.
Isolated tornadoes will be possible Thursday and Friday.
Very dangerous marine conditions are also expected, with extreme seas
of 20 to 30 feet and higher. A high threat of rip currents and large
and dangerous breaking waves in the surf zone will produce extremely
hazardous beach conditions.
POTENTIAL IMPACTS
-----------------
* SURGE:
Prepare for life-threatening surge having possible devastating
impacts across most low lying areas in Eastern North Carolina.
Potential impacts in this area include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers.
Numerous small craft broken away from moorings with many lifted
onshore and stranded.
Also, prepare for life-threatening surge having possible significant
to extensive impacts across most low lying areas in Eastern North Carolina .
Also, prepare for locally hazardous surge having possible limited
impacts across northeastern areas of North Carolina.
* WIND:
Prepare for life-threatening wind having possible devastating impacts
across southern portions of Eastern North Carolina, especially along the
coast. Potential impacts in this area include:
- Structural damage to sturdy buildings, some with complete roof
and wall failures. Complete destruction of mobile homes. Damage
greatly accentuated by large airborne projectiles. Locations
may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and
roadway signs blown over.
- Many roads impassable from large debris, and more within urban
or heavily wooded places. Many bridges, causeways, and access
routes impassable.
- Widespread power and communications outages.
Also, prepare for life-threatening wind having possible significant
to extensive impacts across southern portions of Eastern North Carolina.
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible major
impacts across Eastern North Carolina. Potential impacts include:
- Major rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals, and
ditches overflow.
- Flood waters can enter some structures or weaken foundations.
Several places may experience expanded areas of rapid
inundation at underpasses, low-lying spots, and poor drainage
areas. Some streets and parking lots take on moving water as
storm drains and retention ponds overflow. Driving conditions
become hazardous. Some road and bridge closures.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across
Eastern North Carolina. Potential impacts include:
- The occurrence of isolated tornadoes that 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, chimneys
toppled, 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, 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:
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.
Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
There is a threat from tornadoes with this storm. Have multiple ways
to receive Tornado Warnings. Be ready to shelter quickly.
