Although less likely, hurricanes have the potential to reach homes as far north as Long Island, N.Y. and impact states as far inland as Illinois. The key to staying safe this hurricane season is preparation. Residents in an area at risk for severe storms should prepare an emergency plan, create an emergency supply kit, and learn local hurricane evacuation routes. If an evacuation is ordered, -do not delay and get to safety as soon as possible. To help with preparations, OnStar and the American Red Cross have partnered to create the Hurricane Preparation Checklist.
