Here is a simple checklist to help you prepare for a storm.

Divert your downspouts away from your house and remove debris from exterior drains.
If you have a sump pump, make sure it is working.
Charge all of your electronic devices and portable chargers.
Find your flashlights and backup batteries. Place flashlights throughout the house.
Fill up your gas tanks.
Unplug sensitive electronics

Putting together an emergency kit is also a great idea. For more information on preparing for power outages, visit http://www.redcross.org/prepare/disaster/power-outage.
