Eugene Weather Alert: Overnight Cold Snap Could Damage Gardens by Early Tuesday
EUGENE, OREGON — A sharp chill is sweeping across western Oregon as a Fall Frost Advisory blankets the Willamette Valley, marking the season’s first widespread cold snap early Tuesday morning. The National Weather Service in Portland warns that temperatures could dip into the low to mid-30s, threatening tender plants, outdoor pets, and late-season crops.
Frost Advisory Details and Affected Areas
The Frost Advisory includes Lane, Linn, and Benton counties, covering communities such as Eugene, Springfield, Albany, and Corvallis from midnight through 9 a.m. Tuesday. Drivers along Interstate 5 and Highway 99 may encounter patchy frost on bridges and shaded rural areas during the morning commute.
Residents are urged to cover or bring sensitive plants indoors and to protect garden beds from frost damage overnight.
Risks to Plants, Pets, and Travel
Forecasters caution that frost formation could damage or kill unprotected vegetation, posing a risk to home gardens and local farms. Those planning early-morning travel should allow extra time for windshield defrosting and remain cautious of slippery conditions on rural routes.
Outdoor pets and livestock will also need added protection from the overnight chill, as temperatures near freezing could cause stress or cold exposure.
Outlook for the Rest of the Week
Skies will stay mostly clear through Tuesday, helping temperatures rebound by afternoon with highs around 64°F. Conditions will remain calm and sunny midweek before Pacific moisture returns late Thursday, bringing another round of light showers to the region.
The early frost marks the beginning of a typical October weather pattern in Oregon — crisp mornings, sunny afternoons, and steadily cooler evenings as the area moves deeper into fall.
