Weather can greatly impact the<unk>  of those at<unk> . Therefore, you should make a point to be aware of weather conditions while on the water. The National Oceanographic and Atmospheric Administration (NOAA) transmits recorded messages of the latest local weather information on VHF-FM radio every 4-6 minutes. Updates occur every 2-3 hours. WX-1, WX-2, and WX-3 are the stations this information can be found at. The Coast Guard broadcasts weather information on VHF channel 22.
Boaters should be aware of certain storm warning definitions to be able to respond appropriately. A small craft advisory has winds of 19-38 mph, and<unk>  conditions may be dangerous for small boats. A gale warning has stronger winds of 39-54 mph. A storm warning has even stronger winds of over 55 mph. Once winds reach 74 mph or greater and are due to a tropical cyclone, a hurricane warning is issued. Lastly, a special marine warning occurs when winds of 40 mph or more are anticipated to last less than two hours.
Waterspouts and hurricanes are other weather phenomena to be aware of. Waterspouts are maritime tornadoes with revolving winds that may exceed 250 mph. They usually last for 30-60 minutes and can be avoided by steering a course perpendicular to the projected path. Hurricanes are a type of tropical cyclone. They are classified as a tropical depression, tropical storm, or hurricane in order of increasing severity based on wind speed. The Saffir-Simpson Hurricane Wind Scale rates hurricanes from 1-5 based on intensity. Hurricanes are called typhoons in the western North Pacific Ocean and cyclones in the Indian Ocean. In the Northern Hemisphere, winds blow counterclockwise around the eye or center, which is relatively calm. In the Sothern Hemisphere, winds blow clockwise around the eye. The best<unk>  measure against hurricanes is to avoid them, which can easily be achieved thanks to meteorological technology.
