LOS ANGELES (CNS) – A heat advisory was in effect Tuesday for much of Los Angeles County as temperatures begin climbing well above normal, with forecasters warning that the hottest conditions are expected through midweek.
The advisory, issued by the National Weather Service, will be in effect through 9 p.m. Thursday for the valleys, the San Gabriel Mountains and the Los Angeles County inland coast, including downtown Los Angeles.
“Afternoon high temperatures are forecast to be mostly around 3-8 degrees above normal, with coastal areas forecast to reach the upper 70s to upper 80s and low to middle 90s for inland valleys,” according to the weather service.
Forecasters said the heat is expected to peak Wednesday as a strong area of high pressure expands into Southern California.
The weather service warned that the heat could pose health risks for vulnerable groups, including young children, older adults, people without access to air conditioning and those spending extended time outdoors.
Higher humidity is also expected to add to the discomfort during the afternoon hours.
“Admittedly under normal conditions, these temperatures would not necessitate any heat products,” NWS forecasters said regarding the heat advisory. “However, given the current influx of visitors and numerous outdoor events across the county, there is a higher risk for heat-related problems, especially given that humidities will be higher than normal.”
A slight chance of showers or isolated thunderstorms is also in the forecast from Tuesday into Wednesday as a surge of mid-level moisture moves into the region.
Forecasters said most areas are expected to remain dry, but any storms that develop could produce gusty winds and lightning. Forecasters noted that much of any rainfall could evaporate before reaching the ground because of very dry lower-level air.
Temperatures are expected to begin easing later in the week, although conditions will likely remain above normal through the weekend.
