Units housed in structures not suitable for winds above what mph must be evacuated?

• A. 74 mph
• B. 68 mph
• C. 80 mph
• D. 90 mph

Answer: (A)

Winds reaching hurricane-strength define the point at which structures not built to withstand such forces become unsafe. In emergency planning, hurricane-strength winds start at sustained 74 mph, so units housed in buildings not rated for those winds must be evacuated as soon as winds exceed 74 mph. The other numbers don’t mark the official threshold: 68 mph is still tropical-storm range, while 80 mph and 90 mph are higher hurricane-category speeds but not the boundary used to trigger evacuation.
