Heat likely to hang on through the weekend
Triple-digit heat and humidity may combine for uncomfortable conditions today in parts of inland San Diego County.
“It’s going to be hot in the deserts, but nothing above normal for summertime,” National Weather Service meteorologist Brandt Maxwell in San Diego said. “We’ve had a cool summer so far, so it just feels hot now that we have the real thing.”
Coastal areas will remain temperate with forecast highs of 79 in San Diego and 87 at Oceanside, according to the Weather Service.
“The San Diego valleys, when you get close to the foothills like Ramona and Alpine, will be close to 100,” Maxwell said.
Furthest east in the desert, the high in Borrego Springs is expected to approach 115, with a 20 percent chance of thunderstorms, according to the Weather Service.
Peak heat levels in vulnerable areas during the current warm spell may last through the weekend, according to San Diego forecasters.
For desert areas where temperatures are expected to crest over 110, the Weather Service routinely issues excessive heat warnings.
“Excessively hot temperatures can be stressful to animals and humans ... making it hard for the body to acclimate and remain hydrated,’' the Weather Service said in a statement.
“Extremely warm overnight low temperatures do not allow the body to cool down properly overnight ... and can make extreme heat even more dangerous,’' an excessive heat watch statement said.
Tips for beating the heat include:
— never leave children, elderly people or pets unattended in closed vehicles because temperatures inside can quickly rise to life-threatening levels;
— wear light, loose-fitting clothing with long sleeves and a wide-brimmed hat;
— drink water or sports drinks often — don’t wait until you are thirsty — and avoid drinking alcohol;
— during peak heat hours, stay in an air-conditioned area; if your home is not air-conditioned, visit public facilities such as shopping malls and libraries; and
— avoid unnecessary exertion outside during peak sun hours.
