Me Kayak Brave, You Squall

After some research, seems like I figured out what happened that day the wind blew like no other. I didnt know any better.

WHAT IS A SQUALL

A squall or squall line is an organized line of thunderstorms. It is classified as a multi-cell cluster, meaning a thunderstorm complex comprising many individual updrafts. They are also called multi-cell lines. Squalls are sometimes associated with hurricanes or other cyclones, but they can also occur independently. Most commonly, independent squalls occur along front lines, and may contain heavy precipitation, hail, frequent lightning, [b]dangerous straight line winds[/b], and possibly funnel clouds, tornadoes and waterspouts.

In the Pacific Northwest, [b]a squall is a short but furious rainstorm with strong winds, often small in area and moving at high speed, especially as a maritime term[/b].

The term "squall" can also refer to a sudden wind-speed increase. To be called a squall, the wind must increase at least 18 miles per hour (8 meters per second) and must attain a top speed of at least 25 miles per hour (11 metres per second), lasting at least a full minute in duration.

It is also useful to be familiar with the Beaufort Wind Scale when kayaking and boating.

According to the book Sea Kayak: Safety and Rescue, at Force 8, when the wind is between 34 and 40 knots, kayak conditions are extremely difficult, boat control a problem and kayak to kayak rescues improbable.

At Force 9, 41-47 knots, these are full gale conditions and for most paddlers it will be a fight for survival.

If anyone is interested about paddling and surviving such conditions, the quoted book is real good about not only avoiding danger, but also dealing with them. Sad to say, I hadnt read the WIND chapter before my own personal experience.
