Wind Impacts Definitions
Read this office's detailed Hurricane Local Statement

None

Threat - No discernable threat to life and property; winds to remain below tropical storm-force, but windy conditions may still be present.

Minimum Action - Evaluate personal and community disaster plans and ensure seasonal preparedness activities are complete.

Potential Impact - Sustained wind and gusts below tropical storm force. Unsecured light weight items such as lawn furniture and trash cans may blow around. Rotting small tree limbs may snap; small twigs and leaf clusters may blow off trees. High profiled vehicles may feel a tug at high speeds.

Low Threat - An elevated threat to life and property; the likelihood for tropical storm-force winds (39 to 73 mph).

Minimum Action - Prepare for the likelihood of minor to locally moderate wind damage by securing loose items outdoors. Evacuate if necessary.

Potential Impact - Winds capable of causing damage to unanchored mobile homes, porches, carports, awnings, pool enclosures and with some shingles and siding blown from homes. Poorly constructed homes may receive some wall damage and partial roof removal. Large branches break off trees, but several shallow-rooted and diseased trees blown down. Loose objects are easily blown about and become dangerous projectiles. Winds dangerous on bridges and causeways, especially for high profile vehicles. Many bridges will be closed. Widespread power outages in areas with above ground power lines. A few pool cages and lanai screens will be damaged. Unsecured light weight items may become projectiles, causing additional damage.

Moderate Threat - A significant threat to life and property; the likelihood for hurricane-force winds (74 to 95 mph) of Category 1 intensity.

Minimum Action - Prepare for the likelihood of moderate wind damage by checking disaster supplies, securing loose items and windows, and gathering important personal belongings. Evacuate if necessary.

Potential Impact - Damaging to Dangerous Winds Expected. Winds capable of causing significant damage to mobile homes, especially if older or unanchored. Houses of poor to average construction will have significant damage to shingles...siding...and gutters; more serious structural damage is possible. Unprotected windows may blow out. Many lanai screens and pool cages will be damaged. Well constructed homes will also see shingle and siding damage, especially with longer lasting winds. A few roads impassible due to large debris. Widespread power outages in areas with above ground lines. Unfastened light to moderate weight items will become airborne...causing additional damage and possible injury. Hundreds of wires will be blown down. Many large branches of healthy trees will be snapped...and rotting small to medium sized trees will be uprooted and minor to moderate damage will occur to citrus groves and newly planted lowland crops.

High Threat - A critical threat to life and property; the likelihood for strong hurricane-force winds (96 to 110 mph) of Category 2 intensity.

Minimum Action - Prepare for the likelihood of major wind damage by checking disaster supplies, securing loose items and windows, and gathering important personal belongings. Evacuate if necessary.

Potential Impact - Life Threatening Winds Possible! The majority of older mobile homes will be severely damaged or destroyed. Those that remain will be uninhabitable until repaired. Houses of poor to average construction will have major damage, including partial wall collapse and roofs being lifted off. Many will be uninhabitable until repaired. Well constructed houses will incur minor to moderate damage to shingles, siding, and gutters, as well as blown out unprotected windows. Partial roof failure is expected in industrial parks...especially to those buildings with light weight steel and aluminum coverings. Older low-rising apartment roofs may also be torn off...as well as siding and shingle damage. Up to one quarter of all glass in high rise office buildings will be blown out. Airborne debris will cause damage, injury, and possible death. Power outages will be widespread. Thousands of lines will be pulled down, and dozens of power poles will fall. All trees with rotting bases will uproot or snap. Nearly all large healthy branches will snap. Healthy trees will uproot, especially where ground is saturated. Major damage is expected to citrus groves. Most newly planted crops will be damaged.

Extreme Threat - An extreme threat to life and property; the likelihood for major hurricane-force winds (greater than 110 mph) of Category 3, 4, or 5 intensity.

Minimum Action - Prepare for the likelihood of extreme to catastrophic wind damage by checking disaster supplies, securing loose items and windows, and gathering important personal belongings. Evacuate if necessary.

Potential Impact - Life Threatening Winds Expected! Extremely Dangerous Winds over 110 mph will cause Extensive to Catastropic Damage! All older mobile homes will be destroyed. Houses of poor to average construction will be destroyed or severely damaged. Moderate to major damage of well constructed houses will include up to one half of all gabled roofs. In addition, up to one quarter of exterior walls will fail. Aluminum and light weight steel roofs will be torn off buildings at industrial parks. Partial roof and exterior wall failure are likely at low rise apartment buildings, especially those of poor to average construction. Most windows in high rise office buildings will be blown out, with other minor to moderate damage possible due to swaying. Airborne debris of light to moderate weight will cause additional major damage, as well as injuries and a few fatalities. Near total power loss is expected. Up to one half of all power poles will be knocked down, and hundreds of transformers will pop. The availability of potable water will be diminished as filtration systems begin to fail. Thousands of trees will be severely damaged. Up to three quarters of all healthy small to medium sized trees will snap or uproot, most common on saturated ground. Up to one half of healthy large trees will snap or uproot. Severe damage is expected to citrus groves, some groves may face total destruction. Most of the newly planted ground crops will be wiped out. Livestock left to weather the storm will be injured, some critically. Livestock deaths are likely.
