The National Weather Service issued a thunderstorm warning late Wednesday for the foothills of the Blue Mountains in northeastern Oregon, advising residents and travellers to expect strong winds and hail as a storm moved northeast at about 25 km/h (15 mph).
Timing and immediate hazards
The warning, released by NWS Pendleton at 10:14 p.m., was in effect through 10:45 p.m. and covered communities including Prescott and Pleasant View. Meteorologists warned of wind gusts up to 40 mph (about 64 km/h) and hail roughly the size of marbles (0.5 inches / 13 mm), which can damage vehicles, vegetation and unsecured objects.
"At 10:14 p.m., Doppler radar tracked a strong thunderstorm near Pleasant View, or 18 miles west of Dayton, moving northeast at 25 mph," the NWS said.
The agency noted gusty winds could topple tree limbs and blow around unsecured items, while minor hail damage to vegetation was possible.
Safety guidance
People in the warned area were advised to seek shelter indoors. The NWS reiterated standard lightning and thunderstorm precautions:
- Move inside a substantial building or hard-top vehicle; tents and open shelters offer no protection.
- Avoid touching corded phones, plumbing fixtures and electronic devices during storms.
- Stay away from windows and doors until the storm passes.
- Wait at least 30 minutes after the last thunder or lightning before going outdoors.
For those unable to find indoor shelter, the NWS advises avoiding open fields, hilltops, solitary tall trees and bodies of water. In wooded areas, remain near shorter, denser tree groupings and separate from companions to reduce the risk of current transfer from a ground strike.
Context and consequences
Summer thunderstorms frequently produce localized, short-lived hazards: sudden high winds, hail and lightning. While many storms are brief, their impacts can include downed branches, damaged siding and shattered glass, as well as hazards to drivers from blown debris or sudden hail accumulations on road surfaces.
| Parameter | Value |
|---|---|
| Issued | 10:14 p.m. (NWS Pendleton) |
| Valid until | 10:45 p.m. |
| Storm motion | Northeast at 25 mph (40 km/h) |
| Peak hazards | Gusts up to 40 mph; 0.5-inch hail |
Travelers should exercise caution on area roads; motorists may encounter sudden hail or debris and should reduce speed, turn on headlights and, if possible, stop under cover until conditions improve. Residents should secure loose outdoor items — garbage bins, patio furniture and other objects that can become projectiles in strong gusts — and monitor official NWS updates for any extension or escalation of warnings.
Nationally, lightning is a persistent summer hazard. The NWS estimates tens of millions of strikes occur each year in the United States, with fatalities concentrated in outdoor activities during storms. Preparedness and adherence to the NWS guidance remain the most effective ways to reduce risk during convective events.
