Ida is a Category 4 hurricane. Here’s why that is bad news.
Meteorologists use the Saffir Simpson Hurricane Wind Scale to measure a hurricane’s strength. The scale also estimates potential property damage. The system divides storms into five categories:
Category 1: Winds 74 to 95 mph (minor damage)
Category 2: Winds 96 to 110 mph (extensive damage — can uproot trees and break windows)
Category 3: Winds 111 to 129 mph (devastating — can break windows and doors)
Category 4: Winds 130 to 156 mph (catastrophic damage — can tear off roofs)
Category 5: Winds 157 mph or higher (the absolute worst and can level houses and destroy buildings)
