The development of open water during the winter season in Unalakleet, Alaska has added humidity to the ambient temperature, resulting in a "wet cold" feeling. This has led to a shift from a two layer to a three layer system for staying warm. Additionally, the open water has caused fog to hover near the coast and longer periods of snowfall. The author was held in Anchorage for three days in February due to weather hold conditions caused by snowfall in Unalakleet.

Over the past few months, with the open water development at various stages during the beginning winter seasons to now, the temperature that one feels has changed from the ambient temperature with a wind chill factor to an added component of humidity to the aforementioned temperature effects that make the temperature feel "wet cold." So, it goes from a possible two layer to a three layer system. One of the other impacts due to open water is the fog that seems to hover near the coast.

Flying into Anchorage for the 2017 Alaska Forum on the Environment (AFE) there were patches of it. Furthermore, there seem to be long days of snowfall when it does come down. This was the first time I was held in Anchorage for 3 days starting from February 10-12 due to weather hold conditions caused by snowfall here in Unalakleet.
