Won't be too bad around me tomorrow but everything from the Shoalhaven 3 hours south of Sydney to the Hunter 3 hours north of Sydney is under Catastrophic fire danger tomorrow. They only added Catastrophic to the scale after 170 people died a decade ago in Victoria.
We're talking an area of maybe 6.5 million people, with a lot of urban fringe and regional towns very exposed, being preemptively warned to get away from at-risk areas tonight or early tomorrow.
"Catastrophic" means if a fire starts it's going to be incredibly dangerous, the fire will tavern faster than information. The warning level is don't even wait for specific locality advice, be packed in advance if you're in a fire prone area. If you're in a Leave as soon as you can if there's fire. It's also advised that you can't defend your home at all, and help may not come if there's fire.
They've closed about 600 schools, declared a state of emergency putting the boss of the fire service in charge of a lot of government powers. There's dozens of fires around, though there's currently
not even any fires south of Sydney. Regardless they've still shut down hundreds of schools just precautionarily, because things could get dangerous very quickly if a fire starts. So they don't want any risk of children needing to be moved through fire risk areas.
One idiot with a cigarette, one arsonist, an electric spark, a lightning strike. Doesn't take much.
It's only November, it's not even a very strong El Niño year, but it's been dry and it's windy, and 3 people died immediately the north of the Catastrophic area on Friday. Those fires up north are about to get going again, and there's a couple of sizable towns there:
I think they're telling people on those towns on that second map (Coffs Harbour has 70 000 people) to get as far away from bushland as possible now before things pick up tomorrow. Advice like "do not be west of the highway".
It hopefully won't get this bad, but it's looking grim up there.
Here's a vivid description of what an urban fringe next to a forest full of bomb trees can experience in these conditions.
