The national weather service has issued a heat advisory for the valleys in San Diego County Tuesday morning through Wednesday evening, and County officials are offering tips for how people, their families and pets can stay safe.
Officials expect temperatures to soar into the mid-to-high 90s in local valleys and cities including El Cajon, Escondido, La Mesa, Poway, Santee and San Marcos.
Extremely high temperatures can be dangerous to people and pets and can even lead to stroke or death. Signs of overheating can include exhaustion, dizziness, nausea, confusion and headache. Children and older people are particularly at risk, according to health officials.
Tips to Help Keep Cool and Safe
Head to a Cool Zone. The County’s Cool Zones, including the County’s 33 branch libraries, community centers and other locations, offer people safe, air-conditioned sanctuaries from the heat. Here is a complete list of County Cool Zone sites, their hours and locations. People can call the County Aging & Independence Services call center at 800-339-4661 if they need help finding a Cool Zone site.
Stay in an air-conditioned area during the hottest hours of the day. Even a few hours spent in air conditioning can help your body stay cooler. Do not rely on electric fans for cooling if temperatures exceed 90 degrees.
Wear light, loose-fitting clothing.
Drink plenty of water (avoid alcohol and sugary drinks) and don’t wait until you are thirsty.
Take cool showers.
Never leave a child, elderly person, or pet unattended in a car.
Avoid unnecessary hard work or activities outside during the hottest part of the day.
Avoid unnecessary sun exposure and wear a wide-brim hat if you need to be in the sun.
Avoid using the oven to cook.
Tips to Keep Your Pets Cool in Hot Weather
Keep your pets indoors if the temperature is lower inside.
Exercise pets in early morning hours or early evening to avoid prolonged exposure to the heat. Avoid strenuous runs or hikes.
Keep your pets’ water supply in a tip-proof container, always topped off, and be sure it stays cool (pets will not drink water that is too hot).
Consider a misting system to keep the outdoor areas cooler.
Be sure your pet has shade from the sun ALL DAY long if they are outside. Remember, the sun’s position changes during the day.
Do not take your pets for car trips unless absolutely necessary. A car can heat up very quickly. On an 85-degree day, a car can reach 102 degrees in 10 minutes and soar upward even with the windows down an inch or two.
Don’t take your dogs for walks on the hot pavement. If it is too hot for you to walk barefooted, then don’t make your dogs do it either.
Consider adding a child’s wading pool for your dog. Many dogs will keep cool by “taking a dip.”
Responding to Signs of Heatstroke or Heat Exhaustion
First and foremost, if you find someone who is suffering from symptoms of heatstroke or heat exhaustion — dizziness, nausea, confusion, headache — call 9-1-1 and start cooling them. DO NOT give them fluids to drink. A person with heatstroke may not be able to swallow. Fluids could run down their tracheas into their lungs and make it hard for them to breathe.
After calling 9-1-1, start cooling the person by moving them into the shade, spraying them with cool water and fanning. Place them in a cool shower if they are alert, monitor their body temperatures and continue cooling them.
