Dangerous "Thawing"

Even if the air temperature never gets above -10C, snow melts from the roof of our main building. The reason is that our building is heated and the roof is metal just like the sides so viola, melted snow.

However, if the air temperature is this low, the dripping runoff from the roof re-freezes into icicles like the 4 footer, above. Danger, Will Robinson. If they freeze over doorways that we use we will have to knock them off before they can fall and hurt somebody. If this keeps growing (and doesn't fall from its own weight) I will update in the future.

Click on the Cold Lake forecast on the right and you'll see that we might even have some positive temps in the near future.
