Lil' Lori brought up a good point. We had originally scheduled our helicopter tour of the glaciers for 10:30 a.m. All helicopters were grounded because of the weather. We finally caught the first helicopter out at 2:30 p.m.! The weather can be hit or miss in Alaska.
Also, here is a great website to check the different port cams in Alaska. When you click on the link, I have it lined up to show Juneau's port cam. The colored box on the left is set to show all the ports in Alaska and the United States, just click on each city to see their port cam. It will give you a really good indication of the current weather in each port. http://www.kroooz-cams.com/USindex.html
Have a wonderful time on your cruise to Alaska and please come back and tell us all about it!
