A tropical cyclone is a rotating low pressure weather system with organized thunderstorms, but no fronts. Tropical cyclones with maximum sustained surface winds less than 39 mph are called tropical depressions. Those with max sustained winds 39 mph or higher are call tropical storms. When a storm’s max winds reach 74 mph it’s called a hurricane. The Saffir-Simpson Hurricane Wind Scale is a one-to-five or category based on a hurricane’s maximum sustained winds. The higher category the great the hurricane’s potential for property damage. A category 1 hurricane has winds in the 74-to-95 mph range. Dangerous winds causing minimal damage. Cat 2 winds are in the 96-to-111 mph range. Extreme winds causing extensive damage. Cat 3 winds in the 111-to-125 range are extreme casing devasting damage. Cat 4 produces winds of 130-to-156 mph. These extreme winds cause catastrophic damage. Category 5 see winds of 157 mph or high. Again, extreme and expect catastrophic damage.
