Plumtaw Fire update…
As of yesterday evening, Wednesday, 18 May 2022, the Plumtaw Fire had burned 735 acres. Cloud cover helped limit fire growth yesterday.
Multiple agencies are involved and aggressively fighting the fire. For updates follow “USDA Forest Service – San Juan National Forest” and “Archuleta County, CO Sheriff’s Office” on Facebook and this link on InciWeb.
A HUGE thanks to the San Juan National Forest crew and everybody else that is aggressively tackling the fire!
Smoke and air quality yesterday afternoon and this morning…
At Stevens Field the high yesterday afternoon was 77 and the low this morning was 37. Humidity yesterday afternoon bottomed out at 12%. Winds yesterday afternoon peaked at 30mph at 12:55pm. In O’Neal Park we hit 35mph.
Precip summary… A few raindrops fell in a couple of spots, but it wasn’t enough to wet the ground.
*** The Grand Junction National Weather Service has issued a RED FLAG WARNING valid 11am to 10pm Thursday. Conditions will be favorable for easy ignition and rapid spread of fires. ***
*** The Grand Junction National Weather Service has issued an AIR QUALITY HEALTH ADVISORY valid until 9am tomorrow.
IMPACTS…Moderate to heavy smoke can be expected Thursday morning for areas in close vicinity to the Plumtaw wildfire, including Pagosa Springs. Air quality will improve by late Thursday morning as atmospheric mixing increases and smoke lifts into the atmosphere. However, periods of moderate to heavy smoke will be possible downwind to the east of the fire along the Archuleta and Mineral County line, and additional heavy smoke impacts will be possible across the San Luis Valley. By late Thursday evening smoke will begin to drain to locations south and southwest of the fire, including Pagosa Springs, bringing occasional heavy smoke through early Friday morning. *** This will be the trend for a while.
*** As of yesterday at 9am, Archuleta County implemented a STAGE 1 FIRE BAN. As of 12:01am tonight, The San Juan National Forest will enter STAGE 1 FIRE RESTRICTIONS. ***
Things have changed… The system is expected to be stronger and have more moisture and precip. Unfortunately we will just get scraps.
Winds – Everything I look at indicates that winds will peak in the 40-45mph range both today and tomorrow. The NWS is under-forecasting tomorrow’s winds by 10-15mph. Normally I wouldn’t point this out, but it will impact the fire. As far as a Red Flag Warning tomorrow, humidity will creep up just a tad (low teens today and then upper teens tomorrow) which might push us barely out of Red Flag criteria. Regardless, 40-45mph winds are still trouble.
Precip – The system will approach from the northwest and then track across northern Colorado. It will favor northern Colorado and the Front Range – we will just get scraps. Slightly good news for us is that we’ll get a little precip, more clouds, and higher humidity which will help slow fire growth. I expect our mountains to get 1-3” of snow above 9,500ft.
Dust – I’m not confident that we’ll get dust. The fetch isn’t quite right.
Travel – Northern Colorado and the Front Range are going to get impressive snow for this time of year. Travel will be impacted tomorrow and Saturday. Additionally heavy wet snow will likely break tree branches and some folks are likely to lose power.
