Not a lot you can do now. Clear the yard of anything that might become flying debris... but that won't stop missiles from elsewhere.
Hope the 'cane just deals your neighborhood a glancing blow and doesn't cause high winds.
AFTER it's blown over, what you do becomes all important; repair branches as best you can, clear away debris, etc. Give them a nice foliar feeding, not too strong, mix in some Safer Insecticidal soap to knock down any bugs that might have blown in. You're outdoors, so trying to run a pump or lights from batteries or a generator isn't needed, count your blessings- because the power outage usually lasts a lot longer than the wind and rain.
