Smoke Worsens For Region's Inland Valleys, Some Possibility Of Weekend Relief

Aug 6, 2018

UPDATE: FRIDAY, AUG. 10, 11:00 a.m. --- Can the air quality in southern Oregon and northern California's inland valleys get worse? Yes, apparently it can ...

Overnight, several locations in the Rogue Valley slipped from merely Unhealthy Air Quality Index readings to Very Unhealthy or Hazardous. 

An inversion layer that's been keeping a damper on the fires burning in much of the region is expected to lift today, making fires more active. Burnout operations are being conducted on several fires, as well, creating still more smoke.

Southwest winds forecast for today and Saturday may clear out some residual smoke, making for improved air quality over the weekend. But areas downwind of the most active fires can expect continued unhealthy conditions.

Here are some representative AQI ratings from around the region ...

OREGON: 

GOOD: Eugene,  Cottage Grove, Roseburg, Gold Beach, Agness

UNHEALTHY: Grants Pass, Cave Junction, Provolt, Klamath Falls, Crater Lake

VERY UNHEALTHY: Ashland, Medford, Chiloquin

HAZARDOUS: Shady Cove

CALIFORNIA:

GOOD: Gasquet, Crescent City, Klamath Glan, Eureka

MODERATE: Orleans

UNHEALTHY FOR SENSITIVE GROUPS: Hoopa, Weitchpec

UNHEALTHY:  Yreka, Hornbrook, Weed, Tule Lake, Eagle Lake

VERY UNHEALTHY:  Redding, Anderson

UPDATE: THURSDAY, AUG. 9, 9:00 a.m. --- Increased fire activity in southwest Oregon caused a spike in Air Quality Index readings overnight, with Medford and Ashland hitting Hazardous levels of particulate pollution. By morning the smoke had eased a bit, but most communities from the Rogue and Illinois Valleys to the Klamath-Siskiyou region are still coping with Unhealthy to Very Unhealthy air.

UPDATE: WEDNESDAY, AUG. 8, 11:00 a.m. --  There's slightly better air quality in the Rogue Valley this morning, but it's still pretty grim for most of the inland areas in the central and southern parts of the region.

The fires in southwest Oregon and northwest California remain fairly active. The heavy smoke has put a damper on fire behavior, allowing fire crews to make progress in strengthening containment lines.

Part of that work involves conducting burnout operations which, of course, make more smoke. Burnouts on the Klandike and Taylor Greek fires may increase smoke production in the area today.

Light west/northwest winds are forecasted for today. That means areas south of the fires can expect Unhealthy to Very Unhealthy ait quality readings.

Increased winds on Thursday may help clear the smoke out ... and it may help fan the fires, making more smoke.

UPDATE: TUESDAY, AUG. 7, 2 p.m. -- If you're in the north of the JPR region or along the coast, you're probably breathing pretty easily. But folks in the mountains and valleys of southern Oregon and northern California continue to live with unhealthy levels of smoke from the region's multiple wildfires.

And the weather forecast -- hot, dry and windy -- offers little hope of a respite anytime soon.

UPDATE: MONDAY, AUG. 6, 2 p.m ... Active fire behavior on many of the fires in southwest Oregon and northern California is making for worsening air quality through much of the region.

The South Umpqua Complex, Taylor Creek Klamdike and Nachez fires are producing the majority of the smoke in the area. Lighter winds are expected to lessen fire growth over the next couple of days. But fire crews may use that opportunity to burn out areas of heavy fuel to secure the fire lines, so that will introduce more smoke into local airsheds.

Generally north/northwest winds today are likely to push smoke to the south/southeast, worsening air quality in areas south of the fires, even in areas with Good to Moderate AQI readings.

UPDATE: TUESDAY, JULY 31, 9 a.m. --  Air quality in the mountains and valleys of southern Oregon and northern California continues to be poor, as the fires that are filling the region with smoke continue to grow. 

Still, some areas of the Rogue Valley lightened a bit and air quality oficials hold out hope that coming cooler temperatures and higher relative humidity may help firefighters tamp the fires down, possibly bringing some relief later this week.

ORIGINAL POST: MONDAY, JULY 30, 10:00 a.m. -- The fires in northern California and southern Oregon contine to blanket the inland valleys with unhealthy levels of smoke. But residents of the coast and north of the Rogue Valley are, for now at least, being spared most of the pollution.

Folks in Eugene and Roseburg -- as well as in Gold Beach, Eureka and Klamath Glen -- are enjoying air rated "Good." 

But the ongoing fires in Jackson, Josephine and Shasta counties are yielding Air Quality Index ratings in the "Unhealthy" range or worse.
