· Stay up to date with the latest information. The system track or intensity may change and advisories may be issued.
· Locate or prepare your emergency preparedness kits for your household; stock up on non-perishable food items and water for your household, flashlights, first-aid kits, batteries, matches or lighters, portable stove, toiletries, etc. Visit https://www.ready.gov/build-a-kit for more information on what to include in your supplies list.
· Secure important documents such as birth certificates, tax papers, and insurance documents and keep copies in a water-proof bag.
· Clear loose debris around your yard and store any items that may become airborne with heavy winds, before inclement weather arrives.
· Gas your vehicles and get fuel for your generators now while the weather is clear.
