Fire season has started in the West

someone I know in my local district often goes to help fight fires in the north american continent and also Australia
not sure if he has been called up this time

The era of megafires: the crisis facing California and what will happen next.

Whoa! Video of helicopter pulling replacement power lines in the fire area: https://twitter.com/KRCR7/status/1029106787759226880 8O

Wow! That is something but something! Bravo to these men!

Major wildfires are delivering choking haze to much of the western United States. Ash and smoke are choking Seattle

Not as bad as north of the border in BC last week - https://earther.gizmodo.com/canadas-wildfires-have-turned-day-into-night-1828423184

Well, our air quality went into the toilet today with a lot of smoke and haze. After running around 100 AQI for over a week, the AQI jumped to over 150 this afternoon. Right now, my sensor is reporting 156 AQI and AirNow is reporting 158 AQI. How’s that for closeness? And it is supposed to get worse tomorrow (Friday). I received the following notification late today.

[size=83]A Spare the Air Alert is in effect, Thursday, Aug. 23, and Friday, Aug. 24, for the San Francisco Bay Area.

The unhealthy air quality is due to wildfires. If you see or smell smoke, take steps to protect your health.

This unusual later afternoon alert is being called due to poor air quality conditions developing throughout the region as the result of smoke from wildfires sitting out over the Pacific Ocean and blowing into the region.

Air quality is forecast to be unhealthy today, Thursday, August 23, and tomorrow, Friday, August 24, 2018. The unhealthy air quality is due to wildfires in California, Oregon and Canada. Air quality deteriorated quickly this afternoon due to large plumes of smoke over the Pacific Ocean mixing in with fog and being carried into the Bay Area.

Spare the Air Alerts are called when air pollution is forecast to reach unhealthy levels. Climate change has contributed to longer wildfire seasons which impacts air quality. Smoke can cause throat irritation, congestion, chest pain, trigger asthma, inflame the lining of the lungs and worsen bronchitis and emphysema. Smoke pollution is particularly harmful for young children, seniors and those with respiratory and heart conditions.

When a Spare the Air Alert is called, outdoor exercise should be limited. Residents are encouraged to reduce air pollution every day by rethinking their commute and avoiding driving alone, choosing electric lawn and garden equipment over gas powered and not using lighter fluid on barbecues.

This AirAlert is provided by the Bay Area Air Quality Management District. Thank you for doing your part to Spare the Air!

Do not reply directly to this email. If you want more information on the air quality forecast, or other aspects of the local air quality program, please contact your local air quality agency using the information above.

As an added tidbit, when I compare the PurpleAir map with the sensors on the AirNow.gov map for the SF Bay Area, they are all reporting about the same everywhere. So, chalk one up for PurpleAir. :slight_smile:

Thanks, Niko. I’ll keep that in mind. The air quality around here seems to have gotten better now but, we’ll have to see what happens when the afternoon westerlies kick in.

Shasta County Air Quality Management District has discovered the PurpleAir sensor and installed a bunch of them so now we can see on the PurpleAir Map just how bad the air is around here due to the fires. At time of writing the worst station is showing PM2.5 AQI of 374 with many stations over 300.

The wildfire season isn’t over yet here. Smoke from the Camp Fire in Butte County has made it’s way to the Bay Area. Most of the PurpleAir sensors including mine are registering over 200 AQI. One problem is, my sensor is registering on the PurpleAir map but, it shows 0 in WD. Did something break?

We thought the Carr fire was bad, but the “Camp” fire has burned 70,000 acres of woodland in less than 24 hrs 8O

It is amazing. I read that at one time, the Camp Fire was spreading at the rate of 80 football fields an hour. This seems to be a repeat of the Branscomb Fire near Suisun City that occurred a month ago, same scenario where the wind was blowing all that smoke down into the bay area and the air quality went into the toilet. I hope the wind conditions change soon. The air quality is pretty bad and they say it’s supposed to be like this through the weekend. My air quality information page is sure getting a lot of attention.

According to the 6PM press conference it’s now 90,000 acres and has become California’s most destructive fire in history, having leveled 6,713 structures. The vast majority were homes: a total of 6,453.

Regular evening wind shift to the south, now we have the smoke:

Geeez, just what we need, another historic wildfire. :frowning:

I would like to know what’s going on with the AQI graphics created by WD. It seems like when the AQI hit around 175 AQI, they stopped recording anything or recording garbage. The first graphic is from PurpleAir map which appears normal but the aqi.gif and aqichart.gif are messed up. Any ideas?

Edit: I just took a look at Ken’s AQI page Saratoga-Weather.org - San Jose, CA Air Quality Index and the Realtime AQI chart on his page is doing some weird stuff too.

Edit: Brian, there seems to be a problem with WD creating the PurpleAir graphic and graph when the AQI gets over 175. Can you take a look?

what sensor is this?
purpleair?
I will need a copy of the airquality.txt and airquality2.txt files
