San Diego Swelters Under Record-Breaking HeatwaveSan Diego Swelters Under Record-Breaking Heatwave San Diego is experiencing an unprecedented heatwave, with temperatures soaring to record-breaking levels. The National Weather Service (NWS) has issued an excessive heat warning for the region, urging residents to take precautions to stay safe. On Tuesday, Lindbergh Field reached 103 degrees Fahrenheit, breaking the previous record of 102 degrees set in 2007. The NWS predicts that temperatures will continue to rise throughout the week, potentially reaching 110 degrees or higher in inland areas. The heatwave is being caused by a combination of high pressure over the Southwest and a persistent flow of warm air from the deserts. The hot and dry conditions are creating an oppressive atmosphere, making it difficult for people to spend time outdoors. Health officials are warning residents of the dangers of heat-related illnesses, such as heat stroke, heat exhaustion, and dehydration. The most vulnerable populations, including the elderly, young children, and those with pre-existing health conditions, are at increased risk. To protect themselves from the heat, the NWS recommends that people: * Stay hydrated by drinking plenty of fluids * Spend as much time as possible in air-conditioned areas * Avoid strenuous activity outdoors during the hottest hours of the day * Take cool showers or baths * Wear loose-fitting, lightweight clothing Authorities have opened cooling centers throughout San Diego County, where residents can seek refuge from the heat. Additionally, the San Diego Zoo has extended its hours and is offering discounted admission to help people escape the heat. The heatwave is expected to last through the weekend. The NWS advises residents to continue monitoring weather forecasts and taking precautions to stay safe.
