“People in low-lying areas are advised to move to higher grounds. If you need to go to a shelter, know which shelter you will go to and workout how you will reach the shelter. Check up on family members and neighbors who are in need of assistance. Secure as much food and water as possible. At risk families, the elderly, women, and children are encouraged to weather the storm in a safe dry place. Do not wait until it’s too late to take action.”
