How strong is a Category 4 storm?
Category 4 is the second-highest hurricane classification category on the Saffir–Simpson Hurricane Scale, and storms that are of this intensity maintain maximum sustained winds of 113–136 knots (130–156 mph, 209–251 km/h).
How bad is a Cat 4?
A Category 4 hurricane has wind speeds of between 130 and 156 mph and is considered a major storm. Catastrophic damage will occur. Well-built frame homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles will topple.
What is the Beaufort Scale used for?
One of the first scales to estimate wind speeds and the effects was created by Britain’s Admiral Sir Francis Beaufort (1774-1857). He developed the scale in 1805 to help sailors estimate the winds via visual observations. The scale starts with 0 and goes to a force of 12.
Is 10 mph a lot of wind?
