Description:
The graphic depicts the potential impact from tropical cyclone winds across the specified area valid through the event. It is based on the likelihood of experiencing tropical cyclone force winds and wind gusts combined with the anticipated strength of the winds.
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.
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 - Wind damage is not expected; impact
should be negligible.
Very Low
Threat -
A limited threat to life and property; the likelihood for tropical storm-force
winds (39 to 57 mph).
Minimum Action - Prepare for the likelihood of minor
wind damage.
Potential Impact - A very low impact to communities
within the specified area. Winds capable of causing damage to carports,
awnings, and pool enclosures. Some damage to unanchored mobile homes.
Small branches break off trees and loose objects are blown about. Winds
becoming dangerous on bridges and causeways, especially for high profile
vehicles. Isolated to widely scattered power outages, especially in areas
with above ground lines.
Low
Threat -
An elevated threat to life and property; the likelihood for strong tropical
storm-force winds (58 to 73 mph).
Minimum Action - Prepare for the likelihood of minor
to locally moderate wind damage.
Potential Impact - A low impact to communities in the
specified area. Winds capable of causing damage to unanchored mobile
homes, porches, carports, awnings, pool enclosures and with some shingles
blown from roofs. 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. Scattered power outages, especially
in areas with above ground lines.
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.
Potential Impact - A moderate impact to communities
within the specified area. Winds capable of causing significant damage
to mobile homes, especially if unanchored. Some damage to roofing material,
doors, fences, and windows of buildings. Several large signs and trees
blown down, especially shallow-rooted and diseased trees. A few roads
impassible due to large debris. Scattered power outages, but widespread
in areas with above ground lines. Damage is consistent with that realized
by winds of Category 1 strength on the Saffir-Simpson Scale.
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.
Potential Impact - A high impact to communities within
the specified area. Winds capable of causing significant damage to roofing
material, doors, fences, and windows of buildings, but with some occurrences
of structural damage. Considerable damage to mobile homes. Many large
signs and trees blown down with further damage to standing trees. Some
roads impassible due to large debris. Widespread power outages. Damage
is consistent with that realized by winds of Category 2 strength on the
Saffir-Simpson Scale.
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.
Potential Impact - An extreme impact to communities
within the specified area. Winds capable of causing structural damage
to buildings, some with complete wall and roof failures. Complete destruction
of mobile homes. Numerous large signs and trees blown down. Many roads
impassible due to large debris. Widespread power outages. Damage is consistent
with that realized by winds of Category 3, 4, or 5 strength on the Saffir-Simpson
Scale.
