@Weather_West  @DavidBanuelasH  @linhanhcatey  Daniel. I heard of a few people coming down with Valley Fever. We also had a big hit with VF during the Northridge quake with all the dust from the shaking.

Patchy dense fog will develop across portions of the #CentralCoast  this evening and continue through much of the overnight hours. Visibility 1/4 mile or less will be possible. #cawx  #SBAweather  #SLOweather

A barn fire that occurred in Atascadero was so hot, that a couple of black pixels representing heat was picked up on GOES-W Fog Product Satellite Imagery around 7:51 PM PST this evening. @KSBY  @tvdave  #CAwx  #SLOweather 

Elevated to brief critical fire weather conditions today across interior areas due to offshore winds gusting 25-35 mph, RH 4-10%, and temps 82-92°. Increased threat of fire ignitions. Be extra careful with fire ignition sources. #LAWeather  #cawx  #Socal

Extremely critical fire weather conditions tonight-Thursday as strong and damaging #SantaAnaWinds  combine with single digit humidities. Very rapid fire spread, long range spotting, and extreme fire behavior likely. #LAwind  #LAWeather  #cawx
