(Coastal Flooding) |
| 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.
