From what I have read about the fire, I don't think there was really enough time - not just to evacuate but to even realize just how badly this fire was going to blow up. The initial fire was spotted around 6:45am - first tweet from @CALFIRE_ButteCo came at 6:51am when it was 10 acres and spreading (not uncommon). The first evacuation, for the town nearest the fire, Pulga, came at 7:23am from the Butte County Sheriff. The next tweet was at 8:02am, when it had grown to 1000 acres, and a minute later they called for the eastern portion of Paradise to evacuate. At 8:41am, the tweet evacuating most of central Paradise came through, with it being expanded 10 minutes later.
By then, most people were probably already at work, so there wasn't time to go home and grab any personal belongings or pets. And, given that one of the main roads heading south and out of danger was already under evacuation orders, I'm not sure how much traffic was being allowed out in that direction, but was instead being funneled down 2-3 other roads that headed south and southwest away from the fire zone. As it was, some of the burning embers still managed to fly in the wind and cross a major highway southwest of Paradise and just south of Chico, though thankfully, the fire was contained just on the west side of the highway.
My friend who made it out with her grandmother posted on her FB at 10:53am that they had made it out safely. By that point most of Paradise as well as the town just to the north of it, Magalia, had been evacuated - looking at the evacuation zone maps, the only parts of Paradise not under evacuation orders at that point were the far southwestern, outlying parts of town. At 11:15am, @CALFIRE_ButteCo tweeted that the fire had grown to 5000 acres, and at 1:02pm, it was 8000 acres. The last part of Paradise to be evacuated occurred at 1:36pm.
To be honest, it is a minor miracle that the winds died down last Thursday night and Friday, otherwise it is quite possible that portions of Chico would have burned as well. This fire is not unlike the Tubbs fire that swept through Santa Rosa and the other ones that affected the Napa and Sonoma valleys last year. I will say, having lived in the West my entire life and having a brother who worked for the National Forest Service as a firefighter during the summer of 1994 (a very bad year - most infamous for the 9 Hot Shot firefighters who died in Colorado), that people who live in these mountain communities are very aware of the persistent fire danger and do take the necessary precautions. I'm just not sure, with the number of people living in that area, as well as the lack of proper line maintenance by PG&E (Pacific Gas & Electric), the inability of the Department of the Interior to correctly manage our forests (and before anyone attempts to politicize this to blame Trump - these forest mismanagement policies have been going on since at least the mid-80s thanks to lawsuits from groups like the Sierra Club), the refusal of the state, county and local governments to enact appropriate, fire-resistant building codes, etc that we can realistically expect a different outcome than the one Paradise had. I kind of just shake my head and thank God I don't live in California anymore and pray that the same issues with big-city Democrats taking over the state legislature down there don't have the same impact on our forest management practices here in Oregon.
To follow up, I did find this article, from the San Jose Mercury News that is pretty disturbing regarding the evacuation alerts, on so many levels -
