Santa Ana, California — A heat advisory has been issued for the Santa Ana Mountains, Foothills, and Orange County, with expectations of high temperatures and potential heat-related health risks. The advisory, released by the National Weather Service (NWS) on Monday at 9:53 a.m., is in effect from 10 a.m. on Monday until 8 p.m. on Tuesday, June 17.
Temperatures are anticipated to reach into the low 90s, particularly in areas east of Interstate 5, where the hottest conditions are expected. The NWS has categorized the heat risk as “Widespread Moderate HeatRisk,” indicating a significant likelihood of heat illnesses. Individuals, especially outdoor workers, are advised to review heat safety guidelines to protect themselves from the impact of extreme temperatures.
Residents and visitors in Orange County are urged to stay informed about local weather conditions and take necessary precautions against the risks associated with prolonged exposure to high heat. This includes staying hydrated, minimizing outdoor activities during peak heat hours, and recognizing the signs of heat-related illnesses.
Despite the heat, some areas may experience patchy fog; however, it is not expected to be as dense as it was on Monday morning. Inland regions can anticipate sunny skies, while coastal areas will observe hazy sunshine. Temperatures along the coast are forecasted to remain comfortable, lingering in the upper 70s.
Specific temperature predictions indicate that parts of the inland valleys, foothills, and mountains may experience daytime highs approximately 10-15 degrees above normal, primarily ranging from the mid to low 90s. Such temperatures can create challenging conditions, particularly for vulnerable populations.
Looking ahead, a gradual cooling trend is expected as the week progresses. An onshore flow will return, paving the way for cooler conditions by the weekend, coinciding with the first weekend of summer. However, current forecasts suggest that no significant chances of rainfall are on the horizon, leading to persistent dry weather.
The NWS emphasizes the importance of taking heat advisories seriously and suggests that people remain vigilant and prepared. With summer approaching, understanding the potential effects of extreme heat can help ensure the safety and well-being of all residents in the area.
As this heat advisory unfolds, local health officials and emergency services are ready to assist those affected by heat-related health issues. It is crucial to remain aware of weather updates and health recommendations to navigate this challenging weather pattern safely.
