...THE NATIONAL WEATHER SERVICE CONTINUES TO OBSERVE MAY 18th
THROUGH 24TH AS NATIONAL SAFE BOATING WEEK...

...Marine Forecasts...

The following is a safe boating message from the National Safe
Boating Council the National Weather Service and NERACOOS,
reminding you that National Safe Boating Week is May 18th through
May 24th.

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.

Typical marine forecasts predict wind speed and direction, wave
heights and periods,roughness of near shore waters, and
significant weather. Marine forecasts cover large areas and the
forecast elements are often given in ranges. The significant
weather may not occur over the entire area or during the entire
forecast period. The ranges represent average conditions over a
period of time (usually 12 hours) and the actual conditions may be
lower or higher than the forecast range. Boaters should plan for
conditions above and below the predicted ranges.

Take particular note of any current advisories and warnings,
including Small Craft Advisories, Gale or Storm Warnings which
alert mariners to either high winds or waves occurring now or
forecast to occur up to 24 hours from now. Special Marine Warnings
are issued for sudden increase in winds to over 35 knots (40
mph), waterspouts (tornadoes over water), and hail of one inch or
greater and indicate a more immediate threat. Marine weather
statements bring attention to significant, rapidly changing
conditions on the water including increase in winds, non severe
thunderstorms, development of dense fog and even snow squallsor
strong and gusty rain showers.

You should have a marine VHF transceiver with built-in NOAA
Weather Radio channels. If you venture beyond about a 25 nautical
mile range from shore, you should consider buying a good quality
HF single sideband transceiver and satellite phone.

Before setting out, obtain the latest marine forecast and warning
information from http://www.nws.noaa.gov/om/marine/marine_map.htm
or NOAA Weather Radio and check the latest ocean conditions at
www.neracoos.org/realtime_map. You can also receive specialized
forecasts for Sebago Lake and Lake Winnipesaukee at
http://www.weather.gov/gyx/recreation

Several days ahead of time you can begin listening for extended
outlooks which give general information out to the next five days
in both graphical and text format.

This message was brought to you by the Northeast Regional Ocean
Observing System, NERACOOS, National Weather Service and the
National Safe Boating Council.
