Several fires are burning between Prineville and John Day, as well as other parts of the state. The largest of these is the Corner Creek Fire, located 11 miles south of Dayville, OR.  Yesterday, this fire grew to  approximately 10,000 acres by 4 pm.  Here's a photo from yesterday:

Smoke could be seen from the MODIS sensor on the Aqua Satellite overpass yesterday afternoon.

Air quality in Burns degraded to the moderate category for an hour last night, around 7 pm, but quickly rebounded to the good category.   

Fire growth is expected today with the hot, dry weather.  Today's smoke forecast shows light (pink) and moderate (dark pink) around Dayville and Mt. Vernon, with smoke traveling to the south of the fires.  

Forecasted 24-hour average PM2.5 for Thursday July 2, 2015. 

On Friday, light smoke is expected to travel south-southeast of the fires, as shown below.  

Forecasted 24-hour average PM2.5 for Friday, July 3, 2015.

On Saturday, July 4th, light smoke will travel to the southeast of the fires, as shown below.

Forecasted 24-hour average PM2.5 for Saturday, July 4, 2015.

As always, with the night time temperature inversion, smoke could settle into valleys in heavier concentrations.  Smoke typically lifts from the valleys within an hour or two after sunrise this time of year.

Although the following message is primarily addressing wildfires, we know that these can be large sources of smoke, which can affect communities for weeks.  As such, it seems appropriate to post this on the Oregon Smoke Blog.

A reminder from the Pacific Northwest Wildfire Coordinating Group


PORTLAND - With the July 4th holiday approaching, the Pacific Northwest Wildfire
Coordinating Group (PNWCG) would like to remind outdoor recreationists in Oregon and
Washington to use care to prevent wildfires. Parts of the region have not had significant
precipitation since mid-March, and conditions are very dry across many areas in both states.
Wildfires can start and grow much more easily when conditions are dry.

Discharging fireworks or explosives, including exploding targets, is prohibited. Fireworks can
cause costly and dangerous wildfires, especially when conditions are hot and dry and vegetation
is receptive to sparks. Fireworks and exploding targets are prohibited at campgrounds and
elsewhere on public lands. Recreationists should also check on local fire restrictions before
heading out, and consider whether a campfire is necessary.

In 2014, 1,293,685 acres burned in wildfire. Almost half of the 4,572 fires reported in
Washington and Oregon were human caused and could have been prevented. Firefighters and
land managers need everyone’s help to prevent wildfires this holiday and through the summer.

The National Weather Service Climate Prediction Center seasonal drought outlook shows
drought conditions in all of Oregon and nearly all of Washington will likely persist and increase
through September, creating conditions that will lead to larger and longer wildfires once they
start. While there is nothing we can do to prevent lightning-caused fires, extra caution to prevent
accidental human-caused fire starts will be especially important all summer long.
“Wildland agencies work together year round to protect and maintain healthy and fire resilient
landscapes, support fire adapted communities and coordinate safe and efficient wildfire
response,” said PNWCG Chair David Summer. “We all have a role to play in protecting our
beautiful public lands here in the Pacific Northwest. Please take care to avoid starting a wildfire
when recreating this season. Protect what you love.”

Five new large wildfires started in Oregon over the weekend which will created moderate smoke impacts in parts of central and eastern Oregon.   As of this morning, DEQ monitors in LaGrande, Enterprise, and Sisters were all showing moderate air quality.  Surprisingly, the monitor in John Day was showing good air quality. The DEQ monitor in Baker City is not reporting data.

 During the night, smoke is expected to drain into the valleys.  Communities down valley from the fires are expected to received smoke impacts.  Any smoke reports from Baker City or other locations around the state receiving smoke would be appreciated.

Buckskin wildfire is winding down

Update on the Buckskin Wildfire for June 23, 2015

The Buckskin Fire has grown to 4,993 acres as firefighters continued burnout operations yesterday along the southern perimeter near Baldface Creek. Overall containment has improved to 45%. Today, crews along the southwest edge of the fire will work to complete interior burnout operations. Helicopters will support the burnout with bucket drops, sling load cargo off the line and shuttle personnel.
Crews working the eastern flank are in various stages of mop up, repair and monitoring. WIldland Fire Modules on the western flank continue to monitor the inactive fire edge. The fire area will continue to smolder and creep in the drainage creating visible smoke until a season ending event occurs, likely later in the Fall.
