Canadian ice map from today. An ice bridge has formed between IR and Ontario. That shade of purple means ice is 3"-6" thick, though I suspect a good wind will blow it away. We haven't seen an ice bridge in years.

You can't really tell much from the NorthShore camera but it honestly doesn't look like it yet. Its hard to tell from the NOAA site either, I see some starting on the 15th & 16th but i don't see a 17th data set yet.

Well let's not tell the wolves! They might see this as an opportune moment to abandon the U.S. and escape to Canada.

One formed last week (from about McCargoe Cove to Ontario), but it broke up in the wind. We'll see how long this one lasts.

Tuesday, February 18th update. The ice bridge has gotten bigger, but may be short lived, Big warmup forecasted for next week.

Today, 2/20/2025 was a rare clear day.
