Ice Jam In Alaska!
Over the past week flood events were observed in the Bahamas, Colombia, Czech Republic, France, Norway, Sweden, and United States (Alaska, Hawaii, Middle Mississippi Valley, North Dakota, and Texas).
This week we will take a closer look at flooding caused by ice jams. Flooding caused by ice jams is usually experienced in cold climates. Lower water levels in rivers may result in the formation of large sheets of ice on river surfaces. Rapidly increasing water levels and temperature can cause the ice sheets to break up into large slabs of ice. As the ice slabs are forced downstream by rapidly moving water, they may become jammed and form dams which result in massive flooding upstream. (OSHA)
Below, let’s take a closer look at a recent ice jam-caused flooding event in Alaska.
Flooding: Alaska, United States
A large ice jam in a bend on the Yukon River backed up water 40 to 50 miles upstream. Galena, located about 15 miles upstream from the ice jam, was largely covered by water and almost all residents were reported to have evacuated from the area. The flood is being described by some residents as the worst flood ever. (RSOE EDIS)
The latest forecast for Galena, Alaska depicts warm temperatures for the rest of the week, with a chance of precipitation later on. (Weather Underground)
