Wildfire smoke from several blazes will blanket most of the Portland area Saturday, Sept. 10, with varying depths of brown haze extending beyond the coastline. Air quality should evolve over the day with the wind direction.
Multnomah County health officials banned burning wood on Saturday citing the Portland air quality. The ban followed a July 25 one by the Multnomah County Fire Defense Board. Burning wood for cooking is allowed.
Relief from the heat and poor air quality is forecast to arrive late Saturday, early Sunday by a dominant southerly flow. Eventually, the prevailing wind will come from the west Sunday and Monday.
A red flag warning is in effect through Saturday night across a large swath of Oregon and Washington. Strong east winds continue to dominate the Cascade ridges all the way down to the sandy beaches. Winds of 20-30 mph with stronger gusts of 40-50 mph are possible during the morning and afternoon.
Power shutoffs have been ordered in high risk areas to avoid a repeat of the Labor Day fires of 2020. Expect high temperatures in the low to mid 90s Saturday up and down the Willamette Valley. Areas covered in dense smoke can expect cooler temperatures than what is forecast.
