Officials encourage the public to check and replenish their emergency disaster kits. Emergency disaster kits should include at least a 14-day supply of non-perishable food, one gallon of water per person per day, a battery-powered radio, a flashlight, an extra supply of prescription medicines, and other items tailored to individual and family needs. A smaller, portable go-kit is also recommended should you need to evacuate. County, state, and federal officials will continue to monitor the situation and actively coordinate in preparation.

The public is advised to check conditions before venturing out for hiking, river, or beach excursions. River and stream crossings, recreational trails, and other outdoor recreation areas may quickly become hazardous. Do not cross swollen rivers or streams; always check with a lifeguard at any lifeguard station before entering the ocean. Know before you go.

Standard tips to prepare for power outages include:

• Use surge protectors to protect your appliances and equipment
• Turn off and unplug all unnecessary appliances or equipment
• Keep a portable battery-powered radio and flashlights with extra batteries
• Stay away from downed lines and report emergency incidents to 9-1-1
