No, we aren’t going to get ‘toxic rain’ from the #Campfire smoke

I’ve been asked to write this, because this silly fear mongering keeps making the rounds on social media.

It has about the same level of sophistication as the disproved idea that “chemtrails” are raining poison on us from the skies, and comes from an uneducated set of premises cobbled together.

The #CampFire as seen on November 9th, 2018, captured by Landsat8. Note that this was the period when the most toxic smoke was being produced, due to buildings and vehicles burning and it was blown to the southwest that day. Since then, the fire line is mostly in wildland areas burning trees and brush and the original toxic smoke has long since dissipated and blown to sea.

Here’s the straight facts.

  1. Yes, it is going to rain in the areas devastated by the #Campfire. Yes, that will cause some problems such as possible flash flooding and ash runoff into creeks.
  2. Most of the really toxic smoke from the fire happened during the first two days when structures and vehicles were burning, which had fuel, plastics, household chemicals, and other substances mixed in. That smoke has either dissipated from the atmosphere or has already been blown out to sea. It doesn’t remain suspended over the fire area. See the image above of the smoke plume, all of the most toxic smoke was blown to the southwest.
  3. The existing fire line is well outside city limits and burning trees and brush, rather than building an automobiles. The current smoke we are experiencing is no worse that what you’d get from a wood stove or a fire you make while camping.
  4. Due to the fact that the temperature inversion capping smoke in the valley floor the past week finally dissipated yesterday, air quality in Chico and surrounding areas has dramatically improved and is now at 147 as of this writing. Source. Even if there was still “toxic smoke” from the original time remaining in the area, there would be little of it to be precipitated out with rain.

Even better, the forecast suggests that by the time we get rain, the particulate level will be even lower.

When the rains come, it won’t take long for the particulates (smoke particles) to be washed out of the air. The air will be clean and safe to breathe. It won’t become toxic as water, acidic, or poison. There’s just too little of it per volume of water to be a health risk.

There’s no danger from rain after a wildfire, and anyone who says there is doesn’t know what they are talking about. Even Snopes agrees.

Please share this widely to fight ignorance and fear.
