It peaks and ebbs. Every time new fuel shows up, there'll be a big flare up, but the overall situation is gradually getting better. They're getting an onshore flow in most of the Cypress area which means they're going to be having a rough night on the east end of the fire.
Locally, the big concern was to save the water treatment plant, an effort that was successful. Most of the Valley Parkway canyon area is looking okay, with most of what's burning located in "islands". They're still having some shakey moments on the north side of the pass. That'll probably go on through tomorrow morning.
The big prayer now is for those new starts elsewhere to end.
