Unseasonably Warm Temps and Low Humidity Heighten the Threat of Wildfire

Post Date:10/22/2019 1:09 PM

The unseasonably warm temperatures and low humidity are heightening the threat of wildfires across Southern California. The high winds will weaken briefly on Wednesday, October 23, and then gain strength in some areas on Thursday and into the weekend. Friday will bring the highest elevated fire weather conditions.

Fire safety officials encourage residents to be extra vigilant over the next few days. Residents should avoid activities that could result in a spark or heat exposure to fuels that could start a fire such as:

  • Mowing or using powered yard equipment after 10 am
  • Outdoor welding or grinding
  • Any outdoor fires
  • Careless disposal of smoking materials such as tossing cigarette butts
  • Operating or parking cars or other motorized vehicles on or near dry vegetation

With the low humidity and low fuel moisture along with the return of high winds towards the end of the week, fuel is very easy to ignite and will burn surprisingly fast, leading to rapidly growing and spreading fires that are difficult to extinguish.
