See how different parts of the state have been impacted by wildfire smoke over The average number of heavy wildfire smoke days from 2015-2021-you can really Of the grid cell) a heavy smoke polygon were counted. The daily heavy HMS smoke polygons during wildfire season were overlaid withĤkm grid cells, and the number of days each grid cell intersected (at any part More likely to indicate the presence of ground-level smoke. These polygons use daily GOES satellite imagery to categorize theĭensity of smoke as light, medium, or heavy. Mapping System (HMS) smoke polygons developed by the National Oceanic andĪtmospheric Administration’s (NOAA’s) Office of Satellite and Product Look at the frequency and duration of smoke events. The most recent smoke event and put this wildfire season into context in comparison withĮcology's Air Monitoring Coordinator, Jill Schulte, put together these useful maps to It’s the end of October, and while there are still a fewĪctive fires, it looks like the rain is here to stay.
#MOUNTAIN SPOKANE WEATHER UPDATE#
A reminder that the latest air quality conditions and 5 day smoke forecast are shown in the map at the top of this page, and we'll update the blog as needed. At this time it's uncertain how much of that transported smoke will reach the surface and how much will stay above us in the atmosphere. We're also keeping an eye on the wildfires burning in Alberta and British Columbia-shifting conditions to winds from the north could lead to smoke impacts in Washington State next week. It's also likely that local smoke impacts from firework displays and usage will linger into the morning of July 5th. If recreating, check local fire restrictions and consider if a campfire is necessary.īased on the hot and dry weather, some areas may observe Moderate to Unhealthy for Sensitive Groups air quality intermittently through the weekend and holiday. Please exercise extreme caution if igniting fireworks. Fires can start and spread much more easily in hot and dry conditions. Please keep in mind that fireworks not only contribute to smoke but also are responsible for starting new fires. We will continue to monitor the situation and update as Sensors in Skamania county along the Columbia river are showing USG smoke impacts from the Tunnel Five fire. So far we expect impacts to be local, but models show that some smoke Air quality in Shelton is currently at Unhealthy For Sensitive Groups and smoke impacts are expected to persist for the time being. Lines to prevent the fire from spreading.
That started yesterday afternoon and has burned around 250 acres as of last count. Tonight depending on how many fireworks are left over.Īlso, there is a wildfire near Shelton, the McEwan fire,
Given that, we may see another (smaller) pollution spike We don’t expect more of that smoke in the near future, though the fires are still burning and the possibility of smoke later on remains. The wildfire smoke from British Columbia, which arrived earlier in the day on July 4 th, only pushed us from Good to Moderate. The majority of the pollution we saw last night was due to fireworks. This will dilute the smoke and continue to improve – when the air near the ground heats up and rises, bringing smoke with it.
With another hot day today we should see good vertical mixing Quality has greatly improved and most areas are Moderate. Particularly true in Pierce County where air quality was in the Very Unhealthy Smoke from British Columbia, and fireworks led to very high air pollution last The combination of good weather (a high pressure system), wildfire
