Preparation OBSERVATION PREDICTION
Sun and clear sky in the morning
Thermal sea breeze
Onshore winds (sea breezes) during the day, and offshore winds (land breezes) during the night usually dying in the morning.
Increasing strength during the day as the land heats up and decreasing or dying at night as the land cools. Expect the wind to veer (shiſt clock- wise) as velocity increases. In some parts of the country, increasing sea breezes will be accompa- nied by growing cumulus clouds.
Calm, overcast days
Cold and warm fronts
High cirrus clouds
Cumulus clouds growing taller (cumulonimbus)
Dark clouds approaching
Continued calm and overcast.
Showers or rain, changing air temperature, winds shiſt direction. Cold fronts usually move faster than warm fronts.
A warm front with rain and changing winds should appear within 12-48 hrs. Clouds will get lower and more dense as the front gets closer.
Tunderstorms and strong winds.
LOCAL WEATHER CONDITIONS
Weather constantly changes. Recognizing the patterns of your local conditions, such as winds that increase every afternoon, makes planning easier. Some other clues about impending weather are changes in wind direction, cloud patterns and falling temperatures.
Squalls or storm which may include strong winds, heavy rain, or both.
WARM AIR WARM AIR
Te barometer measures air pres- sure and helps predict weather. A rising barometer usually means good weather approaching, and a falling one warns of poor weather.
COLD AIR
A cold front is a mass of colder air overtaking a warmer mass. Cold fronts are more abrupt and create harsher conditions. Squally, windy weather is associated with them.
COLD AIR
A warm front is a mass of warmer air overriding a cooler mass of air. Warm fronts are typically more gradual and bring humidity result- ing in rain.
A VHF radio tuned to a weather channel keeps you informed about changes and emergencies.
