(Apologies for the outside topic, but I thought this might be of interest to those who are familiar with the coastal areas near Stanford.)
About 7:30PM Tuesday, evacuations were ordered for much of the area of southern San Mateo County and Santa Cruz County on the west side of Skyline. At 11PM, the evacuation area was enlarged further. And more at 1:30AM, totaling about 200 sq miles, including Boulder Creek to near Pescadero. News conference scheduled for 6AM (!!)
CalFire calls this the CZU August Lightning Complex (@CALFIRECZU). CalFire reports 7500 acres burned (11.7 sq miles) as of 11PM. 0% contained.
At 11PM, the satellite sensing showed 5 separate large burn areas in that region, totaling about 8 to 9 sq miles.
At 2AM, the satellite sensing (MODIS/Terra) shows a very much larger area (about 80 sq mi) but I believe(hope) this was sensing the hot smoke from the fires. UPDATE: 4:30AM: A second satellite sensor is now showing about an 80 sq mi area as fire, consistent with the latest evacuation orders.
I see tweets at Calfire around midnight saying that Big Basin is already burning and Russian Ridge Open State Park is going to burn.
You can dig down to various maps from this USDA Forest Service page.
At my house (near El Camino Hospital, about 11mi NE of the nearest fire), we had a fair amount of smoke in the late evening hours. About 4AM, the smoke smell isn't too bad, but I can see that there is smoke in the light of the street lights.

Time lapse Tuesday night of explosive development of the fire
For those that don't know, California, which had a relatively cool July, has had a very hot August. We've had rolling blackouts since Friday due to too much demand for electricity. Then early on Sunday morning (3AM), a big electrical storm started coming ashore between Santa Cruz and Napa, heading NE. I'm in the Mountain View/Sunnyvale area and went outside at that time and was surprised by near continuous flashes of lightning to the SW, while the storm was some 35 miles from me (still offshore). I've been through really bad electrical storms in Texas, and this was getting close to them in terms of lightning strikes per minute. I believe I saw one estimate of 2500 ground strikes of lightning, but my lightning detector app showed far greater numbers, but must be measuring cloud-to-cloud strikes.
To see the strikes for this storm, visit LightningMaps.Org and set the clock to 2020-08-16 0:00 UTC and apply. To see the storm continue, advance the clock to 2020-08-17 0:00 UTC.
