WEATHER & WATER CONDITIONS
Before a boating outing check the weather conditions. As we all know
the weather can change rapidly in many parts of the country. It does
so sometimes without being predicted. NOAA weather radio reports
are continuously available on designated frequencies installed on
VHF radios and various handheld devices. Also, many local radio
stations carry weather reports.
Cloud Formations
Clouds indicate the type
of current weather and
upcoming changes in
the weather. Knowing
the type of cloud
formations can assist
you in choosing the
appropriate boating day
or if already on the water
will help you understand
any upcoming weather
changes
Flat clouds (stratus)
normally indicate stable
air. Cumulus clouds
indicate unstable air.
Many times a “cotton ball” or cumulus cloud builds vertical height
in the a ernoon and the result is a thunderstorm with increased
winds and waves; sometimes these storms are quite violent. You
can nd additional information on weather (meteorology) at your
local library.
