For preparations in the US...

I've been directly hit by three hurricanes on the coastline, and my opinion is "if you have to ask, evacuation is the answer". Others with more experience will likely say the same - the list of things you need is long, varied and not obvious.

Food, water and cooking fuel for 3 weeks. The means severals gallons of water per person per day for 20+ days, not a drop less. If you don't feel silly storing so much water it's not enough.

Axe and pry bar, chainsaws, chains, chain oil, gas. You may have to cut your way out of shelter and will spend a few days clearing roads.

Heavy boots and heavy gloves. There is sharp-edged debris everywhere and no emergency medical treatment for a while, so avoiding needless risk is important.

A flashlight is good for inspecting the shelter immediately after the storm passes but otherwise don't work at night - stepping on a nail is a real possibility and never worth it.

There are plenty of displaced fireants and snakes as well as nails and glass so a medical kit ought to contemplate those as well.

The main thing is to remember if that the "first responder" is several days away, maybe 2-3 weeks. And supplies need to last that long unrefrigerated.
