|
| None |
Threat -
No discernable threat to life and property; sustained winds to remain below
tropical storm-force, but conditions may be hazardous for small craft operators.
Minimum Required 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 sustained tropical
storm-force winds of 39 to 57 mph.
Minimum Required 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 minor damage to carports
and awnings. 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
power outages affecting individual neighborhoods or islands possible. |
| Low |
Threat - An elevated threat to life and
property; the likelihood for strong tropical storm-force winds (58 to 73
mph).
Minimum Required Action - Prepare for the likelihood
of minor to locally moderate wind damage. Shuttering of windows and glass
doors may be required to minimize damage caused by wind-blown debris.
Potential Impact - A low impact to communities in the
specified area. Winds capable of causing damage to unanchored mobile
homes, porches, carports, awnings and with some shingles and small portions
of roofing blown off. Some poorly constructed signs damaged. Large branches
break off trees, but several shallow-rooted and diseased trees blown
down. Some large trees uprooted if heavy rainfall occurs. Loose objects
are easily blown about and become dangerous projectiles. Winds dangerous
on bridges and causeways, especially for high profile vehicles. Scattered
power outages, effecting entire neighborhoods and possibly several islands. |
| Moderate |
Threat -
A significant threat to life and property; the likelihood for hurricane-force
winds (74 to 95 mph) of Category 1 intensity.
Minimum Required Action - Prepare for the likelihood
of moderate wind damage, including shuttering windows and doors.
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 unshuttered
windows and doors, and fences. Some damage to shingles, tiles and other
roof coverings, with some loss of roof decking on older buildings. Several
large signs and trees blown down, especially shallow-rooted and diseased
trees. Several large trees uprooted if heavy rainfall occurs. A few streets
may become impassible due to large debris. Some wire-mounted traffic
signals may fall. Scattered power outages affecting several islands likely,
with possible temporary outages affecting large sections of the Keys.
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 Required Action - Prepare for the likelihood
of major wind damage, including shuttering windows and doors.
Potential Impact - A high impact to communities within
the specified area. Winds capable of causing significant damage to roof
decking, shingles and tiles, and especially unshuttered windows and doors.
Some structural damage can be espected on older frame homes, commercial
buildings and warehouses. Considerable damage to mobile homes with many
mobile homes sliding or overturning and older mobile homes completely
destroyed . Many large signs and trees blown down or snapped. Some roads
impassible due to large debris. Several wire-mounted traffic signals
downed with some damage to pole-mounted signals. Widespread power outages
throughout the Keys likely with some wooden utility poles snapped. Some
street lights and may become bent. |
| 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 Required Action - Prepare for the likelihood
of extreme to catastrophic wind damage. Shuttering of windows and doors
is required.
Potential Impact - An extreme impact to communities
within the specified area. Winds capable of causing structural damage
to especially frame homes and commercial buildings, some with complete
wall and roof failures. Some major damage to roof structure and coverings
on reinforced concrete block structures. Complete destruction of mobile
homes. Numerous large signs and trees blown down. Many roads impassible
due to large debris. Widespread power outages throughout the Keys with
numerous traffic signals and street lighting damaged or destroyed. Some
major damage possible to communications towers. Damage is consistent
with that realized by winds of Category 3, 4, or 5 strength on the Saffir-Simpson
Scale. |
