Read this office's detailed Hurricane Local Statement


Threat - Sustained winds up to 38 mph with gusts up to 45 mph.

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


Threat - Sustained winds 39 mph to 57 mph with gusts of 46 mph to 73 mph.

Impact - Tropical storm force winds expectedMinor to moderate damage may occur to many mobile homes. Poorly constructed homes may receive some roof damage. A few houses may have minor damage to roof shingles and siding. Unsecured light weight items, like garbage cans or patio furniture, may become projectiles, causing additional damage. Some power poles or electrical wires will be blown down, creating localized power outages.

Most newly planted trees and shrubs could be damaged or uprooted. Some small trees will be uprooted, and large branches will snap.


Threat - Sustained winds 58 mph to 73 mph with gusts of 74 mph to 95 mph.

Impact - Strong tropical storm force winds expected with hurricane force gusts possible.

Most mobile homes will experience major damage. Some of poor construction will be destroyed. Houses of poor to average construction will have moderate damage to shingles, siding, and gutters; structural damage is possible. Unprotected windows may blow out. Well constructed homes will also see shingle and siding damage with some roof damage possible, especially with longer lasting winds.

Unfastened light to moderate weight items will become airborne causing additional damage and possible injury. Hundreds of power poles and wires will be blown down. Power outages will affect entire neighborhoods.

Many large branches of healthy trees will be snapped with small to medium sized healthy trees uprooted. Nearly all rotting trees will be uprooted.


Threat - Sustained winds 74 mph to 95 mph with gusts of 96 to 110 mph.

Impact - Life threatening winds of category one intensity expected.

All mobile homes will be severely damaged or destroyed. Those not destroyed will be uninhabitable until repaired. Houses of poor to average construction will have major damage, including partial wall collapse and failure of roofs. Some will be uninhabitable until repaired. Well constructed houses will incur minor to moderate damage to shingles, siding, and gutters, as well as unprotected windows blown out. Roof failure of these homes is possible.

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 well as siding and shingle damage. Airborne debris will cause damage, injury, and possible death.

Power outages will be widespread. Thousands of power poles will be snapped with lines pulled down.

All trees with rotting bases will uproot or snap. Many Large healthy trees will snap or uproot, especially where ground is saturated. Many crops will be damaged or destroyed.


Threat - Sustained winds greater than 95 mph with gusts greater than 110 mph.

Impact - Life threatening winds of at least category two intensity expected!

All 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 removed. 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. Airborne debris of light to moderate weight will cause additional major damage, as well as injuries and a few fatalities to those not inside a sturdy shelter.

Total power loss is expected. At least one half of all power poles will be knocked down. The availability of potable water will be diminished as filtration systems fail from a lack of power.

Thousands of trees will be severely damaged. Many healthy trees will snap or uproot, most common on saturated ground. Most of the ground crops will be wiped out. Livestock left to weather the storm will be injured, some critically. A few livestock deaths are likely.

Category three, four, or five impacts:

For category three, four, or five Hurricanes:

Major hurricane force winds capable of unprecedented destruction!

Most of the affected area will be uninhabitable for weeks, perhaps longer in some instances. At least one half of well constructed homes will have roof and wall failure. All gabled roofs will fail, and those homes will be destroyed. The majority of industrial buildings will become non functional; partial to complete wall and roof damage is likely. All wood framed low rising apartment buildings will be destroyed. Concrete block low rise apartments will show major damage, including some wall and roof failure.

Airborne debris will be widespread and include heavy items such as household appliances and even some light automobiles. Sport utility vehicles and light trucks will be moved or tossed. Needless to say, the blown debris will create additional destruction. People and pets caught outdoors will face certain death if struck.

Power outages will last for weeks as most power poles will not remain standing and transformers will be destroyed. Water shortages will make human suffering incredible by modern standards.

The vast majority of native trees will be snapped or uprooted. Only the heartiest will remain standing, but be totally defoliated. Few crops will remain standing. Livestock left to weather the storm will be killed.
