CHAPTER 1

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 upcomingweather

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 afternoon and the result is a thunderstorm with increased winds and

waves; sometimes these storms are quite violent. You can ﬁ nd additional

information on weather (meteorology) at your local library.
