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.

6/30/15 Air Quality Update: Wenatchee Area



Smoke and Forecast: 
The Sleepy Hollow Fire has very little smoke production at this point.
Three weather words for today: HOT, DRY, & WINDY.  NW winds will increase this afternoon and cool temperatures a bit.  Wednesday, the hot and dry pattern continues through at least Saturday, and likely longer.
Other fire starts in mountainous areas have started to pop up.  With highs near 100F today and then topping out each day above 90F, wildfire smoke should not be an issue for the next few days.

Quick Info
Smoke impacts from wildfires can happen quickly.  Stay informed with some of these links and sites.
 
Precautions
Many state, federal, and county lands have campfire and firework restrictions.  Contact the specific campground, land management agency, or county for more information.
