Cat carrier ideas? Please help

So there’s a cat 3/4 hurricane heading straight toward me, the eye is supposed to hit 11 miles from my house. If it’s a 4 or above we will evacuate and I don’t want to leave my cat but I don’t have a cat carrier. I haven’t checked in stores and haven’t gotten answers from everyone who I’ve asked to borrow one from because obviously that would be ideal, but I’m getting ahead of myself and am planning for the worst here. Obviously it wouldn’t be ideal to have my cat in something that’s not a real cat carrier but does anyone have any ideas of how I could make a makeshift one if need be?
