When boating on a lake and the weather turns bad What should you do first?

Why are storms moving south to north?
By the time a hurricane reaches North America, it generally curves into a northerly direction, as a result of the Coriolis force (which forces a counterclockwise rotation) and steering winds at higher levels. Normal storms, on the other hand, move west to east due to the strong jet stream.
How does wind direction affect weather?
Wind transports moisture and temperature from one area to another, therefore weather conditions change with the shift of wind direction. Feeling a gust of wind could signify a heavy thunderstorm approaching or another atmospheric turbulence.

If a Thunderstorm is Approaching You Make sure everyone aboard is wearing a life jacket. Secure all loose gear, hatches or ports. Determine your location and the best course back to shelter. Keep a sharp lookout for the other boats and obstructions.
What is a common first indicator of bad weather approaching?
The first indicator of bad weather approaching is the buildup of dark clouds.
Which front produces the most severe weather?
Cold fronts tend to be associated with the most violent weather among all types of fronts. Cold fronts tend to move the farthest while maintaining their intensity.
Why do most storms move from west to east?
The reason that they most often move from west to east is due to the jet stream. The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. The jet stream flows around the entire earth. They usually have a meandering, snake-like shape.
Why does weather come from the west?
The reason that they most often move from west to east is due to the jet stream. The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. The jet stream flows around the entire earth.
Which wind direction is the warmest?
In general, winds from the west or southwest are associated with overcast, wet weather. Winds from the south and southeast mainly occur in summer and these bring warm, dry weather. However, southerly winds can sometimes bring hot, thundery weather.
Can you feel a storm coming?
Have you been told you're a human barometer who can sense changes in barometric pressure? You're not crazy and you're not alone. It is possible to feel that storm coming "in your bones" — or in your head.
What is the best wind direction for boating?
Wind conditions Wind speed is measured in knots, which are based on nautical miles. Five-knot winds or less will be barely noticeable, and you should have calm seas and ideal boating conditions. At ten knots, the surface can become choppy, which is usually OK for inshore boating.
Is it safe to sleep on a boat during a thunderstorm?
There are no specific warnings or advisories for lightning but all thunderstorms produce lightning. A lightning strike to a vessel can be catastrophic, especially if it results in a fire or loss of electronics. If your boat has a cabin, then stay inside and avoid touching metal or electrical devices.
Which is a common first indicator of bad weather approaching quizlet?
The first indicator of bad weather approaching is the buildup of dark clouds.
Which front causes thunderstorms?
cold front A cold front does the same thing with a warm air mass. The warm air is forced to rise because it is less dense than the cold air. This causes a surge of rising motion with is known to generate thunderstorms.
Why do cold fronts bring bad weather?
As a cold front moves into an area, the heavier (more dense) cool air pushes under the lighter (less dense) warm air, causing it to rise up into the troposphere. Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms. As the cold front passes, winds become gusty.
Do storms move north to south?
The prevailing wind direction here across the U.S. is from west to east, which explains why most storm systems move in that direction. However, depending on certain factors, such as jet stream placement and positioning, some storm systems can move from south to north, and even east-to-west!
Which direction do storms come from?
This segment of weather 101 focuses on storm motion and why we generally see storms move from west to east. The easiest answer is the jet stream. In the United States, the wind above our head tends to move in a direction from west to east. These act to steer our storms and move them across the country.

Air moving away from the partial vacuum gets pulled back – so the area in front of the storm experiences a calm. Hence the calm before the storm.
What wind speed makes water choppy?
Wind speeds above 15 miles per hour can make boating uncomfortable, especially if the wind speed is accompanied by choppy water. In addition, the combination of wave and wind motion could necessitate breaking out the seasick medication for those not accustomed to spending time on boats.
Is 15 knots rough?
At ten knots, the surface can become choppy, which is usually OK for inshore boating. However, conditions start to get rough from fifteen knots or more, so unless you've got a very big boat, it's best to avoid heading out!
Can lightning strike the ocean?
Lightning doesn't strike the ocean as much as land, but when it does,it spreads out over the water, which acts as a conductor. It can hit boats that are nearby, and electrocute fish that are near the surface.
Do cruise ships get struck by lightning?
Not surprisingly, the majority of strikes are on sailboats (four per 1,000), but powerboats get struck also (five per 10,000). Trawlers have the highest rate for powerboats (two per 1,000), and lightning has struck houseboats, bass boats, and even PWCs.
