Alaska records hottest-ever December
- This is amid an unusual winter warm spell.
- Temperatures soared to a record 19.4 degrees celsius on the island of Kodiak, almost 7 degrees warmer than the state's previous high.
- Elsewhere in Alaska temperatures have been plunging to record lows.
- The weather extremes have prompted warnings of an "Icemageddon" from authorities, as torrents of rain and snow have left ice as hard as cement coating the roads.
