When the maximum sustained winds of a tropical storm reach 74 miles per hour, it’s called a hurricane. Hurricane Season begins on June 1 and ends on November 30, but these powerful storms can occur before and after the official season.

The terms “hurricane” and “tropical cyclone” refer to the same kind of storm: a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation.

Once a tropical cyclone reaches maximum sustained winds of 74 miles per hour or higher, it is then classified as a hurricane, typhoon, or tropical cyclone, depending upon where the storm originates in the world.

A hurricane watch means that hurricane conditions (sustained winds of 74 mph or higher) are possible within the specified area. A hurricane watch is issued 48 hours in advance of the anticipated onset of tropical-storm-force winds in an area.

The following is a compilation of NOS's roles and responsibilities before, during, and after a hurricane. NOAA's National Ocean Service (NOS) brings a wealth of coastal science, management, and operational expertise to aid communities impacted by …

Powerful winds aren't the only deadly force during a hurricane. The greatest threat to life actually comes from the water — in the form of storm surge. See for yourself with this video from NOAA's Ocean Today.

Historical Hurricane Tracks allows users to search by place name, storm name or year, or latitude and longitude points. With the search results, users can generate a map showing the track of the storm or storms accompanied by a table of related information.

2024年6月16日 · Fourteen of 20 hurricane-force wind events underwent bombogenesis in the North Atlantic during the first two months of 2014. This unusual activity can be seen in wind speed data from the period. In this image, blues indicate areas with wind speeds that are faster than the 30-year historical average (1981-2010).

Powerful winds aren't the only deadly force during a hurricane. The greatest threat to life actually comes from the water—in the form of storm surge. Storm surge is the abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide.
