The big news right now are all the fires up in northern and central California, many of which I believe were ignited by lightning strikes. Best of luck to the firefighters up there right now.
On our way back from our trip on Monday, we saw some evidence of fire down further south. This was the view from a gas station in Temecula (north of San Diego on the 15):
Pretty crazy, right? Apparently this was smoke from a small brush fire caused by "hot parts from a wheel assembly [coming] off and ignit[ing] the brush" on the 805 near La Jolla. It sounds like it was pretty small and was almost immediately contained, but still made plenty of smoke that we could see from pretty far north.
At least LA managed to make it through several days of 100+ weather without anything major burning... let's hope that luck lasts the rest of the summer.
