Who needs spring when you can just leap frog right into summer? The National Weather Service (NWS) on Thursday, May 11, 2023 issued an “Excessive Heat Watch” starting Saturday afternoon and continuing through Monday afternoon.
NWS says to expect temperatures in the mid-80s to low-90s, which “will pose a moderate, to localized major, risk of heat-related illness.”
“Temperatures will warm on Friday into the mid 70s near the water, to low 80s across portions of the interior. Further warming expected on Saturday into Sunday, with daily record high temperatures possible, especially on Sunday,” NWS said in its forecast discussion. In addition, lows Sunday morning will range from the mid 50s to mid 60s, limiting cooling at night, and thus increasing heat-related impacts over the weekend.”
Cold Water Safety
Forecasters also warned of the dangers of cooling off in what will still be cold water:
“As for impacts during this heat event, the main focus will be on cold water safety, due to river and lake temperatures being in the 40s to mid 50s. It will be important to wear a life jacket, and also be aware of rivers running fast due to mountain snow melt. HeatRisk highlights moderate, with areas of major risk Saturday through Monday throughout Western Washington, lingering for the interior into Tuesday. This level of heat affects most individuals sensitive to heat, especially those without effective cooling or hydration.”
