Pea-sized hail and gusty thunderstorms are expected to hammer the Columbia River Gorge on Wednesday, threatening travel along Interstate 84 and disrupting outdoor plans across the eastern Gorge and nearby towns. Brief but intense storm cells are forecast to bring frequent lightning, heavy downpours and sudden crosswinds in exposed stretches of the canyon.
As reported by OregonLive, the National Weather Service is warning of pea-sized hail (about 0.25 inches) and gusts that could peak around 55 mph. The report highlights several eastern Oregon communities and highway corridors that forecasters say are most at risk.
Storm track and timing
Forecasters say Doppler radar is tracking a line of strong thunderstorms pushing northeast at roughly 40 mph, with activity expected to roll through the Gorge from Wednesday afternoon into the evening. The National Weather Service in Pendleton warns that gusty outflow winds and hail may accompany the heaviest cells and is urging people in exposed areas to keep a close eye on watches and warnings.

Where impacts are likeliest
The alert covers a long stretch of I‑84, including mile markers 174 to 223, and lists Hermiston, Pendleton, Umatilla, Stanfield and Echo as populated areas to watch. Drivers on the interstate and recreationists in canyon pullouts should be ready for sudden visibility drops, falling branches and the occasional hail-dented windshield during the strongest bursts.

Safety and travel tips
Officials urge anyone caught outdoors to get into a sturdy shelter right away and to steer clear of open areas and metal objects. The National Weather Service also recommends waiting at least 30 minutes after the last lightning strike before heading back outside. The National Weather Service notes that lightning and outflow winds are common hazards in storms like these. Although the 55 mph gust projection comes in just under the 58 mph threshold meteorologists use to label a thunderstorm as “severe,” even sub‑severe gusts can knock down weak branches and send unsecured items flying, creating road and property hazards.

If you are traveling I‑84 through the Gorge, build in extra time, secure loose gear and check live road cameras before you go.
