Description:
The graphic depicts the potential impact from tornadoes across the specified area valid through the event. It is based on the likelihood of tornadoes associated with the tropical cyclone occurring across the local area.
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.

TEST.
None
Threat: No
discernible threat to life and property; the occurrence of tornadoes is
very unlikely.
Minimum Action: Listen for forecast changes; review
tornado safety rules.
Potential Impact: None expected; strong wind gusts may
still occur.
Very Low
Threat: A
limited threat to life and property; the occurrence of tornadoes is unlikely,
but cannot be ruled out altogether.
Minimum Action: Prepare for the likelihood of isolated
tornadoes.
Potential Impact: A very low impact to communities within
the specified area. Isolated locations may experience minor to moderate
tornado damage.
Low
Threat: An
elevated threat to life and property; the occurrence of tornadoes is possible,
but less likely than so.
Minimum Action: Prepare for the likelihood of isolated
to scattered tornadoes.
Potential Impact: A low impact to communities within the
specified area. Isolated to scattered locations may experience minor to
moderate tornado damage.
Moderate
Threat: A
significant threat to life and property; the occurrence of tornadoes is
possible, and more likely than not.
Minimum Action: Prepare for the likelihood of scattered
tornadoes.
Potential Impact: A moderate impact to communities within
the specified area. Scattered locations may experience minor to moderate
tornado damage. A few tornadoes may have longer damage tracks.
High
Threat: A
critical threat to life and property; the occurrence of tornadoes is likely.
Minimum Action: Prepare for the likelihood of scattered
tornadoes (even families) with isolated significant tornadoes.
Potential Impact: A high impact to communities within
the specified area. Isolated locations may experience major to catastrophic
tornado damage, among scattered locations of minor to moderate tornado
damage. Some tornadoes may have longer damage tracks.
Extreme
Threat: An
extreme threat to life and property; the occurrence of tornadoes is very
likely.
Minimum Action: Prepare for the likelihood of many
tornadoes (even families) with scattered significant tornadoes.
Potential Impact: An extreme impact to communities within
the specified area. Scattered locations may experience major to catastrophic
tornado damage, among many locations of minor to moderate tornado damage.
Some tornadoes may have longer damage tracks.
Note: In all tropical cyclone situations,
listen for possible tornado watches and warnings. Take cover immediately
if a tornado warning is issued for your area regardless of the depicted
level.
Tornadoes which cause minor to moderate damage: An
EF-0 tornado is weaker in intensity on the Enhanced Fujita (EF) Scale
causing minor damage. Damage to chimneys, porches, screen houses, and
lighter-weight outbuildings; a few downed trees and power lines; large
signs blown over. Tornado wind speeds of 65 to 85 mph. An EF-1 tornado
is of moderate intensity on the Enhanced Fujita (EF) Scale causing moderate
damage. Mobile homes are moved off foundations or overturned; roof surfaces
peeled off buildings; cars blown off roads; several large trees downed
and some power outages. Tornado wind speeds of 86 to 110 mph.
Tornadoes which cause major to catastrophic damage and are considered
significant: EF-2 to EF-5 tornadoes are increasingly strong
to violent in intensity on the Enhanced Fujita (EF) Scale causing major
damage, even up to complete destruction. Mobile homes are completely
demolished; numerous large trees snapped off, totally uprooted, or
debarked; small debris objects (lawn mowers, smaller sections of roofs)
become airborne missiles. Power outages are substantial, extending
over larger areas. Structural damage to sturdy buildings realized,
especially roof and wall failures. However, in the worst situations,
well-constructed walls fail or are even removed; large debris objects
(cars, trucks, larger sections of roofs) become airborne missiles causing
further structural failures. Tornado wind speeds 111 mph or greater,
and in the worst situations 200 mph or greater.
