#Asheville #AQI readings, coming down a bit from their highs around 4:15 for us today.

Still hoping for that rain, y'all.

Screencap from PurpleAir showing much of the WNC region around and south of Asheville. A couple of high readings (not sure why that one to the NW is so high, but the other to the SW is near the TableTop fire)

Numbers in the rest of our area have fallen back to orange, yellow and green, or below about 56. Hoping for a calm night, and for the exhausted firefighters to gain more headway.

Much of this smoke was making itself felt all the way up into the DC area today.

Slightly SW of #Asheville, our #AQI numbers have gone way up, and the 2 windows I had open for an hour trying to bring down the #CO2 #IAQ numbers are now closed again due to smoke.

Really, some rain would be welcome. But just a little, controlled rain. Without lightning. Please.

Definitely a different #AQI sort of day today, currently at 33 PM2.5 here SW of #Asheville.

The winds have shifted direction, and brought the brown, airborne stuff to the people east of Asheville along I40.

Still hoping for the rains to come, and without thunderstorms.

A screencap from the Asheville Citizen-Times excellent map of the fires and smoke in the WNC area.

The tan blob (identified as "medium density smoke') are starting at the Table Rock (in SC) and Black Cove (Polk County, NC) fires, and drifting to the northeast. Cities like Morganton, Hickory and Statesville are doubtless dealing with poor air today.

And the trade-off in keeping the house closed. Headache looming, hard to pinpoint the cause. #IAQ #AQI

CO2 is now 1235

Current #AQI for the #Asheville, #Buncombe, #WNC area via purpleair:

#Widlfires #NCwx https://

Another screencap of the area around us in WNC, shows a wide range of colors, from light green blobs (good) to dark purple (very bad.) Seven fires in the area and slight, changeable breezes are making this a mess for everyone.

Thank you to all the firefighters from all over the nation who are here trying to help us with this.

Another issue here with smoke in the area and poor #AQI is the trade-off we have to make with #iAQ. For unknown reasons, this house simply likes to keep high CO2 levels.

I generally keep 2 windows open on opposite sides of the house regardless of the weather, but we've not been doing that with the #Wildfires

So one day recently we left for 3 hours, came home and found the #Aranet had recorded this CO2 reading.

No heat running. No one home, exhaling. Gas fireplace turned completely off. Windows closed.

What a tradeoff.

An Aranet air quality sensor sits on a brownish countertop. It is currently reading 66.7F and 39% humidity, but the big number is 1193 for the CO2 reading.

As someone who definitely gets headaches with high CO2 levels, this is something of a pain when smoke is high outdoors and one can't open a window.

See that dark spot? That’s where I was planning on going this week. #Wildfires #SouthCarolina #TableRockStatePark #AQI

The smoke that had overtaken our area around noon today has moved elsewhere (at least for now) and we're back into decent #AQI according to PurpleAir. So is @firefly which is great, as we've been trading off the smoke for a couple of days.

Buncombe doesn't currently have fires, and wants people to stop calling the FD about the smoke. Polk does have the fires and isn't letting people know much about them.

We may get rain, but winds are still supposed to be in the 20's tomorrow. Reset, repeat.

No burning. Hope for (just enough) rain.

"A message from the Buncombe County Fire Marshal:
Buncombe County is currently seeing a lot of smoke and haze from wildfires burning in our neighboring counties. The Fire Marshal is urging Buncombe residents not to report smoky conditions to 911 unless you see flames or a column of smoke.

Thank you and please remember we are currently under a statewide burn ban."

It has really rocketed up this afternoon, I'd imagine people are getting nervous. Perfectly clear this morning, terrible quality now. Windows closed and the BlueAirs both running.

not ready to be back in #stlouis after a mini Colorado mountain vacation. and this AQI in the 300s is not making it any better. glad we've still got a stash of N95s... this shit sucks.

Dust detection image from the NOAA GOES satellites, the more magenta/hot pink it is, the more dust. The dust is absolute, choking dust (ie you do not want to be out in it... extremely bad for your lungs). 3/14/25 2329CT #dust #duststorm #OKwx #MOwx #AQI
