Willamette Warnings, Watches and Advisories

Special Weather Statement issued October 31 at 5:33AM PDT by NWS Portland OR

Areas of fog, some locally dense, have developed early this morning the Willamette Valley, Upper Hood River Valley, and southwest Washington lowlands, resulting in roadway visibility of one mile or less. Morning commuters should expected to encounter areas of rapidly changing visibility. Freezing fog is also possible this morning where temperatures have fallen below freezing. If driving, slow down, use your headlights, and leave plenty of distance ahead of you. If walking or cycling, wear bright or reflective clothing and carry a light to increase your visibility to drivers.

When a severe thunderstorm warning is issued, the storm may produce damaging winds, large hail, dangerous lightning, and heavy rain. In some cases, heavy rainfall produced by a severe storm can also lead to flash flooding. Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.
