Key Hurricane Terms You Need to Know
When you live in a hurricane danger zone, you’ll hear a lot of weather words tossed around on the news during storm season.
Many of these key terms are similar, but the subtle vocabulary differences can point you to two very different courses of action.
Here are the key terms, so you can interpret the reports and take action to stay safe.
Types of Warnings and Storms:
A Watch means storm conditions are possible and could be reaching your area within 48 hours or less.
While a watch doesn’t guarantee the storm will reach your area, it is still best to prepare to take action.
A Warning is an announcement that a specified area has a storm moving in, and expected to hit within 36 hours or less.
A tropical storm is an organized system of thunderstorms, with winds of 39 to 73 miles per hour or less. Tropical storms have the potential to develop into hurricanes.
A tropical cyclone with winds of 74 miles per hour or more. Hurricanes are rated on a scale of 1 to 5. The scale is called the Saffir-Sampson Hurricane Wind Scale. Learn more about what the ratings mean.
