Boot Key Harbor, Marsthon, Florida
When a sailor looks to the sky and sees something like this, it gets his instant rapt attention. The picture above was taken by Sharon Thompson on a boat very close to us.
In this case, the weather behind the front turned out to be less than scary. First rain we've had here in nearly a month.
Much scarier was the storm that hit Sydney, Australia a few days ago, see below. The picture at the bottom was said to be taken from the Sydney Harbor Ferry a few minutes later.
None of these pictures are mine.
