PORTLAND, Ore. – A Flash Flood Watch is in effect for portions of central and eastern Oregon as heavy rainfall increases the risk of landslides and debris flows, particularly in areas with steep terrain and recent wildfire burns.
The National Weather Service issued the alert Tuesday afternoon, warning that conditions are favorable for flash flooding from 1:50 p.m. PDT today through 11 p.m. Thursday. Affected areas include central Oregon, the east slopes of the Oregon Cascades, the John Day Basin, the Ochoco-John Day Highlands, and the Southern Blue Mountains.
State geologists caution that debris flows — fast-moving landslides that can carry boulders, logs, and water-saturated soil — pose a serious threat to people, property and roads located below steep slopes or near canyon mouths.
Residents and travelers in the watch area are urged to stay alert and take the following precautions:
-
Monitor weather reports via radio, TV or online. Evacuate immediately if advised.
-
Be aware of unusual sounds like cracking trees or knocking boulders, which may signal a landslide.
-
Watch for sudden changes in stream flow — water turning muddy or flowing irregularly may indicate upstream activity.
-
Travel with caution and assume roads may be unsafe, particularly at night.
