SEATTLE — A Heat Advisory for some areas was extended as western Washington saw temperatures reach into the 90s on Wednesday.
The advisory, originally in effect until 10 p.m. Wednesday, was extended until 5 p.m. Thursday for portions of the Puget Sound region, specifically north to western Whatcom County. The National Weather Service warns overnight lows will only drop to the lower 50s and 60s.
Other areas will see the Heat Advisory expire Wednesday night as overnight temperatures cool. That includes many communities in the South Sound and near Hood Canal.
In the Cascades, a Red Flag Warning is in effect for much of the Cascades at elevations above 1,500 feet. The National Weather Service is warning of hot, dry conditions that make the environment more prone to wildfire. The warning expires at 11 p.m.
Wednesday is expected to be the hottest day of the week, with highs generally dropping below 90 degrees by Thursday.
The NWS warns that there will be a moderate risk for heat-related illness during the Heat Advisory, especially for the young and the elderly, those who work outside, and anyone without access to effective cooling or adequate hydration.
Anyone planning to work or spend time outside is recommended to reschedule their activities to the early morning or the evening.
People should call 911 if they recognize the signs of heat stroke within themselves or others:
- Change in mental state or behavior
- Change in sweating pattern
- Nausea or vomiting
- Flushed skin
- Rapid breathing
- Racing heart rate
- Headache
- High body temperature
