"There is a moderate-to-major risk for heat-related illnesses for pets, livestock, and those who are sensitive to heat, especially those without effective cooling and/or adequate hydration," NWS Bay Area forecasters wrote Wednesday. "Stay hydrated, take cooling breaks, and never leave people or pets unattended in hot vehicles!"
Local officials echoed the need for caution this weekend and called on community members to limit outdoor activity and check on older family members, friends and neighbors. Residents without adequate cooling will be able to find relief at several cooling centers operating at local libraries and community centers.

Here are a few other tips from the county's Office of Emergency Management:
- Drink plenty of water: Drink water even if you don’t feel thirsty. Avoid alcohol, caffeine or lots of sugar because they will speed up fluid loss.
- Limit physical activity: Avoid physical activity during the hottest time of the day—10 a.m.-3 p.m.
- Never leave people or pets in a closed, parked car.
- Stay in air-conditioned areas, whenever possible.
- Cool off by taking a bath or shower: Cool, plain water baths or moist towels work best. Do not cool children in alcohol baths.
- Wear cool clothing: Lightweight, light-colored and loose-fitting clothing can help you keep cool. Cotton clothes are good because they let sweat evaporate.
- Do not bundle babies: Babies do not handle heat well because their sweat glands are not fully developed. Do not put them in blankets or heavy clothing.
- Cover your head: Wear a wide-brimmed, vented hat or use an umbrella when outdoors because your head absorbs heat easily.
- Wear sunglasses and sunscreen: Use sunscreen with SPF 15 or higher when outdoors.
- Rest often in shady areas: Find shady places to cool down when outdoors.
- Check on frail or elderly family, friends, or neighbors often.
