Low Prepare for the likelihood of minor wind damage, primarily to shrubbery, trees, and loose objects. A few older and weaker trees blown down. Isolated power outages possible.
Moderate Prepare for the likelihood of moderate damage with large branches and trees blown down. Some structural damage to buildings. Significant power outages likely. Wind-blown debris will block some roadways.
High Prepare for the likelihood of many trees and power lines down or damaged. Widespread power outages for an extended duration. Major damage to well constructed buildings is possible. Destruction of some poorly constructed buildings is likely Wind-blown debris will make many roadways impassable.
Extreme Prepare for the likelihood of most to all trees and power lines down or damaged. Expect extreme to possibly complete destruction of poorly-constructed buildings and the likelihood of major damage to well-constructed buildings, to include roofs blown off. Most roads impassable due to wind blown debris.
