Get off the lake when you see this cloud formation
This squall line was at the base of a thunderstorm that moved through camp a week ago.
Such squall lines always spell danger. They are the edge of a high wind, how high is impossible to predict. It might be 30 mph and it might be as high as 130 mph (in the case of a wind shear).
Sometimes the clouds in the line can be seen rolling. The line moves toward you very fast.
If you are out on the lake and see such an event, go directly to shore and tie up your boat. You might also prepare yourself for extremely heavy rain and sometimes hail.
If you are near camp, come into the dock but don't try to outrun the clouds for a long distance. If you aren't sure you can get to camp before the storm, go to shore instead and take cover.
This particular squall line and its thunderstorm dumped about an inch of rain on camp in perhaps 30 minutes as well as pea-sized hail.
The blast of wind from it was probably 40 mph.
