General Guidelines for Estimating Wind Speeds

30-44 mph Whole trees in motion. Inconvenient walking into the wind. Light-weight loose objects (e.g., lawn furniture) tossed or toppled.
45-57 mph Large trees bend; twigs, small limbs break and a few larger dead or weak branches may break. Old/weak structures (e.g., sheds, barns) may sustain minor damage (roof, doors). Buildings partially under construction may be damaged. A few loose shingles removed from houses.
58-74 mph Large limbs break; shallow rooted trees pushed over.  Semi-trucks overturned. More significant damage to old/weak structures.
Shingles, awnings removed from houses; damage to chimneys and antennas.
75-89 mph Widespread damage to trees with large limbs down or trees broken/uprooted. Mobile homes may be pushed off foundation or
overturned. Roof may be partially peeled off industrial/commercial/ warehouse buildings. Some minor roof damage to homes. Weak structures (e.g., farm buildings, airplane hangars) may be severely damaged.
90+ mph Many large trees broken and uprooted. Mobile homes damaged. Roofs partially peeled off homes and buildings. Moving automobiles pushed off the road. Barns, sheds demolished.
