Marine Weather Terminology

When you accept the keys to any boat or vessel, you are obligated to become familiar with various marine weather terms and natural events that will help you avoid

Dense Fog Advisory

A dense fog advisory is issued when anticipated widespread fog is expected to appear within a 24 hour period. The fog appears within a designated radius of a 1/4 mile or less and can last for 3 hours or more.

Gale Warning

Gale warnings may sometimes precede hurricane warnings, depending on the wind's speed, consistency, and intensities. A gale warning issue is when winds between 39 and 54 MPH are expected to occur within a 24 hour period. These winds can be frequent gusts or consistent winds.

Hurricane Watch/Warning

Hurricane warnings are advised to be taken very seriously, whether the chance of them actually occurring is high or low. A hurricane watch or warning is sent out when consistent or frequent winds reach at least 74 MPH. These winds often come with high, rough waters out at sea. They are anticipated to appear between 12 and 24 hours. Evacuate any area that has a possibility of this occurrence as quickly as possible.

Inland Hurricane Wind Warning

This warning is when hurricane winds of 74+ MPH begin to migrate toward the shore within 24 hours. A Hurricane is not always guaranteed to occur, but evacuation is recommended in severe cases.

Saffir-Simpson Scale

The Saffir-Simpson scale is an official calculation of wind levels that classify a hurricane. The scale ranges between the numbers 1 and 5, 1 being the least severe and 5 being the most severe. The winds are measured in the following statistics:

  • 2: 96-110 MPH
  • 3: 111-129 MPH
  • 4: 130-156 MPH
  • 5: 157+ MPH

Severe thunderstorm warnings will be sent out when winds reach at least 58 MPH and hail that is at least 3/4 inches in diameter, begins to fall.

Small Craft Advisory

Small craft advisories are directed primarily at smaller vessels when weather conditions might be particularly rough at sea. Be aware of wind speeds and wave heights. If the waves reach 4 feet or higher, you will want to evacuate the area ASAP.

Storm Warning

General storm warnings are when winds are expected to reach 55-73 MPH within a 24-hour time frame.

Tropical Storm Watch/Warning

Tropical Storm warning is announced if, within a 24-36 hour period, there is a storm surge, costal/river flooding, and/or consistent winds between 39-73 MPH. These primarily occur in tropical environments.


A waterspout is a water tornado or a tornado that forms over the water. These are common in tropical areas like the Gulf of Mexico. However, they can form over any body of water, including freshwater lakes and coastal areas.

A warning that is when sustained winds of 31-39 MPH or frequent gusts of the wind between 46-57 MPH are expected to last for 3 hours or more.
