7/8/15 Smoky Haze with Some Relief . . . in Central Washington



Expect smoke and haze to continue through Thursday.  North winds are pushing smoke down into to the Cascade Valleys and Basin.  More Central Washington communities may see air quality in the unhealthy for sensitive groups and unhealthy ranges.  

With high temperatures today and Thursday, air quality may improve slightly as smoke becomes aloft, returning some areas to moderate levels.

Starting Thursday night, a strong cold front arrives out of the Northwest with cooler temperatures and humidity.  Initial relief from the smoke before hazy conditions return due to lighter winds and cooler temperatures.  

Looking Ahead:  Combination of Northwest fires producing heavy smoke with humid air and lighter winds . . . smoke moves smoke down valleys - we could have a smoky start to next week.

7/6/2015 Northwest Clean Air Agency Press Release

(Don't see a document below? Try this link: http://www.nwcleanair.org/documents/7-6-16SmokeAdvisoryFINAL.pdf)

7/6/15 Calm with Smoky Haze

Hot, sunny conditions to continue through today. Northwest timber fires and several fast moving brush fires are producing smoke, creating a generalized haze in Central Washington.  See satellite image below.

Tonight NW wind should push more smoke into Central WA.  Local and newly arrived smoke will settle in most valley locations bringing compromised air quality.

Tuesday through Friday, we may have poorer air quality than we have seen so far this season  . . . expect a range from moderate to unhealthy for sensitive groups.

Stronger winds Friday afternoon should clear the air.

7/6/2015 The Latest View of Smoke From Space

Twice a day the west coast gets a nice, clear picture taken of it from space thanks to NASA and the MODIS (Moderate Resolution Imaging Spectroradiometer) instruments on the Terra and Aqua satellites.
Below is the most recent view from Terra showing smoke swirling around in BC and drifting south into Washington.  A very high resolution version of this image is available here:  http://ge.ssec.wisc.edu/modis-today/index.php?satellite=t1&product=true_color&date=2015_07_06_187&overlay_sector=false&overlay_state=true&overlay_coastline=true&sector=USA1&resolution=250m




NASA is watching the smoke too and posted the following news story about smoky skies over the world cup soccer match in Vancouver, BC yesterday.

7/6/2015 British Columbia Wildfires

Air quality in parts of Washington is being impacted by smoke from wildfires in Canada - so where are those wildfires?  The BC Wildfire Service has a page where they display fire locations.  Clicking the link below will take you to their map which has live links that give more information about each fire.

7/5/2015 Fires and Fireworks

Numerous wildfires are burning around Washington state although fortunately, for the moment at least, none of them are producing major air quality impacts. The air quality impacts we saw around the southern Puget Sound area overnight and today (see the monitoring map with the colored dots) are largely from the firework displays last night. Plus there is an odd, smoky haze hanging around over the southern end of Vancouver Island and the northern parts of Puget Sound (see satellite view below). We seem to be receiving some smoke from our neighbors across the border to the north and are hearing that as many as 60 new wildfires started in British Columbia over the weekend.
The map above shows major fires in the state that have incident management teams assigned to them.  There are other fires around too but they may not show on this map because they are new and don't have a team assigned yet. Or if the local fire responders were able to get it under control quickly, a formal incident team may not be needed. More details on the fires shown above can be found at http://inciweb.nwcg.gov/state/49/#

Air quality impacts seen around the Puget Sound area today at about 1pm (above) are at least in part from the fireworks displays last night but the satellite view below shows it is possible that some is from smoke coming in from BC.

Smoke and clouds can be difficult to tell apart but the bright white masses along the Washington and Oregon coast are surely clouds in the satellite photo above. The wispy, slightly darker stuff is more likely to be smoke.  The big, dark blog over the southern part of Vancouver Island looks to be a pretty impressive amount of smoke from the British Columbia fires. How much of that smoke is headed our way?

7/3/2015 Fire/Air Quality Specialist on the way to Paradise Fire

The Paradise Fire has been picking up steam with the hot weather so the team managing the fire has decided to order a specialist who can help them understand and communicate concerns about air quality in surrounding areas. This specialist - an Air Resource Adviser or ARA - will be arriving in the next day or two with 2 temporary air quality monitors to be installed in Forks and Queets. Until then we can take a look at smoke model output for clues of where the smoke will go. The first picture on the left below shows smoke dispersion expected this afternoon - smoke is expected to go east into the park and could reach the southern part of Puget Sound, depending on how active the fire is. The middle picture is for about 8am on July 4 and shows the smoke drifting a bit more aimlessly, some going west to the coast and some going south/south east. And the final picture on the right is for tomorrow afternoon with smoke traveling to the south along the I5 corridor and east to the Kitsap penninsula.



Below is a shot from the Paradise Fire Facebook page (https://www.facebook.com/pages/Paradise-Fire/831205013596015) showing fire activity on July 2.

7/2/2015 Paradise Fire kicking up some smoke

After remaining fairly contained within Olympic National Park since it started in May, the Paradise fire has been a little more active and a little more smoky the last couple of days. There's currently little concern about smoke reaching high enough concentrations to be a significant health risk in the short term, but visitors to the park and the coast may see and smell some smoke. Morning meteorology is likely to send the smoke down the Queets River toward the coast.  If the fire grows and becomes more active, smoke may reach the Puget Sound area.



Here's a view of the smoke from yesterday, July 1 from the Paradise fire Facebook page.

Since the peninsula generally has such good air quality, there are not many air monitors sited over there to help measure what conditions are like. Various webcams may provide a hint though:

7/3/15 Breathe Easy for Now


Fires Subside, Breathe Easy for Now 
“Hot, hot, hot” temperatures and increasing winds should keep most wildfire smoke above breathing height. 
If winds become too strong, smoke plumes can separate (called plume sheer) from an active fire and lay down into valleys spreading poor air quality.  If any fires begin in the North Central Washington, north winds will blow strong enough to cause plume sheer, starting Friday night, and getting stronger on the Fourth of July.

Weekend Cautions
East Slopes of the Cascades: hazardous fire conditions exist. 
Fire weather warnings and watches in effect at this time through at least Saturday, July 4th.
 
Fuels are very DRY.  Combine dry fuel, wind, and a spark = uncontrollable WILDFIRE.
