Questions
What category hurricane is 115 mph?
Sustained winds of 115 mph (185 km/h, 100 knots) make it a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. A major hurricane. Devastating damage will occur; electricity and water may be unavailable for days to weeks.
What does "sustained wind" mean?
The category uses one-minute sustained winds, not gusts. Gusts can be much stronger than the sustained speed.
Does the category tell the whole danger?
No. The scale only measures wind. Storm surge, flooding rain and tornadoes cause much of the harm, and even tropical storms can be deadly. Always follow local officials’ advice.
