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

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.
