As of Wednesday, April 30, 2014
SEATTLE (AP) — Forecasters and emergency responders are warning Northwest residents to be careful around rivers and lakes as temperatures rise into the 70s and 80s on Wednesday and Thursday.
While the sunshine brings people outside, the Weather Service says rivers fed by melting snow are around 45-to-50 degrees. People who jump or fall in could be immobilized by cold water shock or suffer from hypothermia. They also could be swept away in fast-moving currents.
In addition, warming has raised the avalanche danger for the west slopes of the Washington Cascades and the Mount Hood area.
The National Weather Service says the heat could set records in western Washington and Oregon before things start to cool off on Friday as clouds return for the remainder of the weekend.
