Holy shit my city is on fire

[Bullitt]

Recommended is a good 100ft of open space between your house and trees, brush, and other structures. Good rule of thumb is twice distance your tallest tree measures. Seems like you're in a more suburban than rural area, so get anything flammable out of your yard, pre pack the car with necessities and some valuables. Use the free time now to think about what you want and can take, instead of rushing at last minute if you're given evac orders.
They will give you a rough time frame to get out. Unless it is imminent, which is where it is good to have the car prepacked.
If you have some hoses and sprinklers you should set those up on vinyl siding, wooden eves, and porch/deck. A low constant misting is fine, will help douse airborne embers that land on flammable surfaces. Those water drops from the helos won't hold the fire back. The ground crews need a strong line around it.
