The best time to prepare your finances for a catastrophic event is before it happens, so the FDIC recommends looking over your insurance policies periodically to make sure they're up to date, and be aware of what's covered.
That includes policies for your home and your car.
You also might need extra coverage for things like floods or earthquakes.
Consider taking photos of your property in case you need to make claims.
If you don't already use your smart phone for banking or bill pay, setting it up will allow you to manage your finances from anywhere.
Direct deposits also makes delivery of your paychecks easier during tough times.
Have copies of identification like drivers licenses, social security cards, passports, and other key documents in case you need to restore your financial records.
It's also a good reason to build an emergency fund in case a crisis puts you out of work for an extended period of time.
