Eugene, Oregon – Triple-digit heat could return to the Willamette Valley this week, but Sunday is already shaping up to be dangerous. A Heat Advisory remains in effect from 11 a.m. to 10 p.m. Sunday, with temperatures in Eugene, Springfield, and Albany climbing to 98°F, pushing heat illness risks to a critical level.
According to the National Weather Service in Portland, residents should prepare for intense heat across the South Willamette Valley, especially near I-5 corridor cities like Junction City, Corvallis, and Cottage Grove. With temperatures peaking between 95° and 98°F, the heat index could spike quickly in direct sun.
Local officials urge residents to stay indoors during peak hours, drink fluids consistently, and check on vulnerable neighbors. Without A/C? Use fans, keep blinds closed, and avoid exertion.
Looking ahead, Monday brings some relief with a high of 92°F, but Tuesday and Wednesday could reach 100°F. Overnight lows may not dip below 70°, limiting recovery time and elevating heat-related risks.
Wildfire smoke may also impact air quality, especially if windows remain closed to preserve indoor coolness.
