The National Weather Service defines a hurricane as "an intense tropical weather system with well-defined circulation and sustained winds of 74 mph (64 knots) or higher."

Hurricanes are rated according to intensity on the Saffir-Simpson Hurricane Wind Scale.

The 1-5 scale estimates potential property damage.

A Category 3 or higher is considered a major hurricane.

The National Hurricane Center advises preparedness:

A hurricane watch indicates the possibility that a region could experience hurricane conditions within 48 hours.

A hurricane warning indicates that sustained winds of at least 74 mph are expected within 36 hours.

Predictions:
April 6, 2017 - The Tropical Meteorology Project from Colorado State University predicts that the "2017 Atlantic basin hurricane season will have slightly below-average activity." They predict a total of 11 named storms and four hurricanes.

May 25, 2017 - The National Oceanic and Atmospheric Administration (NOAA) forecasts a 45% chance for an above-normal season, predicting that there is a 70% chance of having 11 to 17 named storms, of which five to nine could develop into hurricanes, including two to four major hurricanes (categories 3-5).

August 9, 2017 - NOAA raises its forecast prediction to 14 to 19 named tropical systems this year, up from the 11-17 they predicted in a previous outlook released in May. Though NOAA's outlook still calls for five to nine hurricanes, the latest update increases the predicted range of likely major hurricanes by one, from 2-4 to 2-5. NOAA forecasters predict the "season has the potential to be extremely active, and could be the most active since 2010."
