Extreme Heat Wave Poised to Scorch Pacific Northwest Next Week
29 Aug
Summary
- Extreme weather chaser warns of "extreme" heat wave
- Temperatures could reach all-time September highs in Portland and Seattle
- Increased risk of heat-related illness and fire danger

According to the latest weather forecasts, the Pacific Northwest and Western Canada are bracing for an extreme heat wave in the coming week. An extreme weather chaser, Colin McCarthy, has warned that some models indicate temperatures could reach all-time September highs in cities like Portland (105°F) and Seattle (98°F).
The impending heat wave is expected to affect a wide region, including Oregon, Washington, Northern California, Idaho, and Nevada. Temperatures are forecast to be as much as 20 degrees above average for this time of year, posing a serious threat to public health and safety.
Alongside the increased risk of heat-related illnesses, the high temperatures also heighten the danger of wildfires. Residents in the affected areas are advised to follow local weather guidance and take precautions, such as staying hydrated and limiting time spent outdoors during the hottest parts of the day.
While long-term weather forecasts can sometimes be inaccurate, AccuWeather has also predicted a late-season heat wave for the Pacific Northwest next week, corroborating the warnings from the extreme weather chaser. Authorities are urging residents to be prepared for the potentially record-breaking temperatures and to take necessary steps to stay safe.
