Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.

Forecast Discussion: Updated Thursday, September 19, 2019 The next few days will be relatively quiet weather-wise with about the only excitement being breezy conditions this afternoon and again on Friday afternoon. The breeziness is associated with a Pacific Northwest low pressure system that will approach and eventually pass by well to our north on Friday. Unfortunately no local precipitation is expected with this system. The Eastern Pacific is a totally different story currently as there are 3 tropical systems churning over that area, Lorena, Mario and Kiko. They are all Tropical Storms currently and all are forecast to reach Hurricane strength at some point over the next several days. Tropical Storm Kiko is the farthest away from us and is projected to keep moving west (away from us), Mario is a little closer to us and is forecast to move north-northwest and be located several hundred miles off the southern Baja Cali coast by early next week. Tropical Storm Lorena is the one we need to keep tabs on as she is the closest to us currently (off the southwestern coast of Mexico) and is forecast to move northward and be off the west coast of Central Baja California by early next week. The main area of concern will be the tropical surge associated with Lorena and the path the storm takes. Initial rainfall projections for our area has a wide range with anywhere from a tenth of an inch to over 2 inches of rain by next week. Stay tuned. As far as the air quality is concerned, mainly good air quality in most places today with Hidden Valley forecast to reach low to perhaps mid moderate for PM10. The ozone levels are all forecast to be in the good AQI category today and Friday due to the afternoon breeziness. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
