Description:
The graphic depicts the potential impact from storm surge across the specified area valid through the event. It is based on the likelihood of storm surge exceeding critical values for the local area.
Important Note: Worded expressions describe the expected impact relative to the latest forecast conditions, while Graphic expressions convey the potential impact relative to the uncertainty of forecast conditions.

TEST.
DISCLAIMER: The impact definitions
described below APPLY TO THE COASTAL AREAS EXCEPT
FOR THE LAKE OKEECHOBEE SURGE IMPACT THAT APPLY TO THE LAKE ONLY. THE LAKE
OKEECHOBEE IMPACT DEFINITIONS DO NOT ACCOUNT FOR THE POTENTIAL OF A BREACH
IN THE HOOVER DIKE. In the event of a breach, all lakeshore communities
could be significantly impacted depending on where the breach occurs. Upon
confirmation of a breach, a flash flood warning would be issued for these
communities by the National Weather Service in Miami (for Glades, Hendry,
and Palm Beach counties) and/or Melbourne (for Martin and Okeechobee counties)
with specific details of potential impacts. Also, the terminology outside
dike protection refers to areas inside Lake Okeechobee that are
not protected by the dike. Likewise, inside dike protection refers
to areas outside Lake Okeechobee that are protected by
the dike.
None
Threat -
No discernable threat to life and property; no surge waters expected.
Minimum Action - Evaluate personal and community disaster
plans and ensure seasonal preparedness activities are complete.
Potential Impact - Coastal flooding is not expected;
impact should be negligible. Surf conditions may still be rough with
minor beach erosion.
Very Low
Threat -
A limited threat to life and property; the likelihood for storm surge and
storm tide waters of 2 feet or less.
Minimum Action - Prepare for the likelihood of minor
storm surge damage.
Potential Impact - A very low impact to communities
in the specified area. Coastal flood waters capable of causing heavy
surf and moderate beach erosion.
Lake Okeechobee Surge Impact - A storm surge which
combined with current lake level could possibly result in total lake
water level of 16 to 18 feet. No impact expected inside dike protection.
Likelihood of minor impact outside dike protection with Kreamer, Torry,
Ritta, and Observation islands, as well as areas around the Pahokee Recreational
Area, in the southeast and south end of the lake partially submerged.
Islands around the Okee Tantie Recreation Area near the mouth of the
Kissimmee River partially submerged.
Low
Threat -
An elevated threat to life and property; the likelihood for storm surge
and storm tide waters of 2 to 4 feet.
Minimum Action - Prepare for the likelihood of minor
storm surge damage.
Potential Impact - A low impact to communities in the
specified area. Coastal flood waters capable of causing moderate to locally
major beach erosion. Very heavy surf breaching dunes in isolated locations,
mainly in historically vulnerable spots.
Lake Okeechobee Surge Impact - A storm
surge which combined with current lake level could possibly result in
total lake water level of 18 to 20 feet. No impact expected inside dike
protection. Likelihood of some impact outside dike protection with Kreamer,
Torry, Ritta, and Observation islands, as well as areas around the Pahokee
Recreational Area, in the southeast and south end of the lake completely
submerged. Islands around the Okee Tantie Recreation Area near the mouth
of the Kissimmee River completely submerged. Likelihood of minor impact
with some flooding possible on Curry Island.
Moderate
Threat -
A significant threat to life and property; the likelihood for storm surge
and storm tide waters of 4 to 6 feet.
Minimum Action - Prepare for the likelihood of moderate
storm surge damage.
Potential Impact - A moderate impact to communities
in the specified area. Coastal flood waters capable of causing major
beach erosion. A few sections of near-shore escape roads weakened or
washed out, especially in historically vulnerable low spots. Surge waters
and wind waves breaching dunes and seawalls in scattered locations to
result in structural damage to a few shoreline buildings, mainly in historically
vulnerable spots. Minor damage to marinas, docks, and piers. A few small
craft broken away from moorings, especially in unprotected anchorages.
Lake Okeechobee Surge Impact - A storm surge which
combined with current lake level could possibly result in total lake
water level of 20 to 25 feet. No impact expected inside dike protection.
Likelihood of major impact outside dike protection with Kreamer, Torry,
Ritta, and Observation islands, as well as areas around the Pahokee Recreational
Area, in the southeast and south end of the lake completely submerged.
Islands around the Okee Tantie Recreation Area near the mouth of the
Kissimmee River completely submerged. Likelihood of some inundation outside
dike protection on Curry Island, including portions of State Road 78
and secondary roads south of Lakeport.
High
Threat -
A critical threat to life and property; the likelihood for storm surge
and storm tide waters of 6 to 8 feet.
Minimum Action - Prepare for the likelihood of major
storm surge damage.
Potential Impact - A high impact to communities in
the specified area. Coastal flood waters capable of causing partial inundation
of the surge zone by sea water, especially for low-lying areas. Severe
beach erosion. Several sections of near-shore roads washed out and/or
low-lying escape roads flooded. Scouring surge waters and battering wind
waves breaching dunes and seawalls in scattered locations to result in
structural damage to several shoreline buildings, with a few washing
into the sea. Damage accentuated by floating debris. Damage to marinas,
docks, and piers. Several small craft broken away from moorings, especially
in unprotected anchorages.
Lake Okeechobee Surge Impact - A storm surge which
combined with current lake level could possibly result in total lake
water level of 25 to 30 feet. Likelihood of some impact inside dike protection.
Likelihood of major impact outside dike protection with Kreamer, Torry,
Ritta, and Observation islands, as well as areas around the Pahokee Recreational
Area, in the southeast and south end of the lake completely submerged.
Islands around the Okee Tantie Recreation Area near the mouth of the
Kissimmee River completely submerged. Likelihood of significant inundation
outside dike protection on Curry Island, including portions of State
Road 78 and secondary roads south of Lakeport.
Extreme
Threat -
An extreme threat to life and property; the likelihood for storm surge
and storm tide waters greater than 8 feet.
Minimum Action - Prepare for the likelihood of extreme
to catastrophic coastal flood damage.
Potential Impact - An extreme impact to communities
in the specified area. Coastal flooding capable of causing widespread
inundation of the surge zone by sea water, possibly reaching several
miles inland for low-lying areas. Extreme beach erosion with several
new inland cuts likely created. Many large sections of near-shore roads
washed out and/or low-lying escape routes roads flooded. Powerful scouring
surge waters and intense battering wind waves breaching dunes and seawalls
in widespread locations to result in structural damage to numerous shoreline
buildings, with several washing into the sea. Damage accentuated from
considerable floating debris. Extensive damage to marinas, docks, and
piers. Numerous small craft broken away from moorings.
Lake Okeechobee Surge Impact - A storm surge which
combined with current lake level could possibly result in total lake
water level of 30 to 35 feet or higher. All areas outside of dike protection
completely submerged. Likelihood of significant impact inside dike protection,
with inundation in areas along and north of Fisheasting Creek, Brighton
Indian Reservation south and west of the Harney Pond Canal, and areas
east and northeast of Highway 27 near Palmdale. Likelihood of minor inundation
near the towns of Lakeport and Buckhead Ridge.
Note: In all cases, listen to local authorities
and obey any evacuation orders for your coastal area. Remember, increasing
wind and rising waters can cut off escape routes well in advance of landfall.
