Tips for a Stormy Sky

Stormy Weather 1

Aug 17, 2016

Recognizing the signs of an approaching thunderstorm and heading for shore well before it arrives is essential to avoiding a potentially perilous situation on the water.

A lot can happen in a matter of minutes. When warning signs become apparent — a darkening sky, the sound of thunder, or increasing cool wind — do not delay. Particular attention should be paid to lines, which affect a large area and almost always herald the arrival of a powerful, long-lasting storm.

Below is a table that shows different thunderstorm situations and the conditions they are likely to bring. In all cases, it is assumed that the storm is in the quadrant from which the weather is moving that usually approaches from the west. Mariners should constantly check the movement of the storm and the position of its core to ensure that they are not in its path.

The Plan

It’s a beautiful morning as we perform our pre-departure checklist, fire up the engines and prepare to release our lines. And if the long-range forecast of very low winds coupled with plenty of sunshine holds, that’s exactly what we need for the areas we plan to explore on this trip! 

We are departing Midland for a week of visiting some of the islands and anchorages within Georgian Bay’s “30,000 Islands” – specifically those along the western edge. These are the less protected islands which face toward wide-open Georgian Bay, where boaters often have to depart the small craft route and work a little harder at setting the hook but are then rewarded with magnificent western views, stunning sunsets, and so much to explore!
