...Public Information Statement...

The following is a safe boating message from the National Safe
Boating Council and the National Weather Service.

Understanding a marine forecast is critical to safe boating.
Weather and wave conditions can change suddenly, catching boaters
off guard and creating life threatening conditions.

Marine forecasts are for wind speed and direction, wave heights,
and significant weather. Marine forecasts cover large areas and
forecast elements are often given in ranges. The significant
weather may not occur over the entire area or during the entire
forecast period (usually 12 hours). Boaters should plan for
conditions above and below the predicted ranges.

Take particular note of any current advisories and warnings,
including Small Craft Advisories and Gale or Storm Warnings which
alert mariners to high winds occurring now or up to 36 hours from
now. Special Marine Warnings are issued for sudden increases in
winds to over 34 knots (39 mph), waterspouts, and hail of 3/4 inch
or greater within the next two hours. Marine Weather Statements
bring attention to brief winds less than 34 knots, dense fog,
blowout tides, and advance alert to major thunderstorm threats
more than two hours away.

You should have a marine VHF transceiver with build-in NOAA
Weather Radio channels. Before setting out, obtain the latest
marine forecast and warning information from or NOAA
Weather Radio. Please utilize these resources during your time
on the water for updates. Marine forecasts are available out five
