Stay out of any room with medium to large trees located outside. Try to convince any elderly neighbors to come stay with you during the storm. I know they will be reluctant, but I can't tell you how many times and ways my dbil (NC firefighter/emt) has put himself in great danger to rescue elderly that refused to leave their homes, but were not capable of taking care of themselves and pets. It is so much safer than trying to get to them in the storm when you think they may be in trouble.
Also Do Not let your teens badger you into letting them go down by the beach Before or After the storm to just "see the water,waves, damage". For many the water can be irresistible with tragic results. Stay safe,we are all praying here in Florida and realize how fortunate we are to have Irene pass by us.
