A Category 3 hurricane, as classified by the Saffir-Simpson Hurricane Wind Scale, is characterized by sustained winds of 111 to 129 mph (178 to 208 km/h). These powerful storms can cause considerable damage to buildings, trees, and power lines, as well as flooding and storm surge in coastal areas.

A Category 3 hurricane on the Saffir-Simpson Scale in 2026 is officially classified as a "Major Hurricane," with sustained winds ranging from 111 to 129 mph (178–208 km/h). This level of storm causes "devastating damage." At Category 3, even well-constructed frame homes will sustain significant damage, including the loss of roof shingles, siding, and gutters. Large trees can be snapped or uprooted, and many roads are likely to be blocked by fallen debris. In 2026, a Category 3 storm is also associated with a 9- to 12-foot storm surge, which can flood coastal roads and inundate low-lying residential areas. Power and water are likely to be unavailable for several days or even weeks after the storm passes. Residents in the path of such a storm are typically under mandatory evacuation orders, as the infrastructure is not guaranteed to remain safe for inhabitation during or immediately after the event, making it a critical threat to life and property.
