RIVERSIDE COUNTY, CA — Santa Ana winds will again gust across the Southland Tuesday and continue into Wednesday, combining with low humidity levels to create a heightened risk of wildfires.
Wind advisories are in effect from 6 a.m. Tuesday to 2 p.m. Wednesday for the San Bernardino and Riverside County valleys, the Inland Empire and the San Bernardino County mountains — including the cities of Banning, Beaumont, Lake Elsinore, Murrieta, Temecula, Wildomar, Riverside, San Bernardino, Ontario, Moreno Valley, Fontana, Rancho Cucamonga, Corona, Crestline, Lake Arrowhead and Running Springs, the NWS said.
The forecast in those areas calls for northeast winds 15 to 25 mph, with gusts to 50 mph.

In addition, the South Coast Air Quality Management District issued a dust advisory through Wednesday for the Inland Empire, San Bernardino County and Riverside County mountains, the San Gorgonio Pass area and the Eastern Coachella Valley.
The South Coast AQMD said areas of blowing dust and sand are predicted throughout the wind event, which may result in "Unhealthy for Sensitive Groups" or higher Air Quality Index (AQI) levels.
Localized areas of blowing ash are possible in areas near the 2020 wildfire burn scars, it said.
The South Coast AQMD encouraged those in areas of direct impact to limit exposure by remaining indoors with windows and doors closed, and to avoid vigorous physical activity.
The NWS, meanwhile, said, "Offshore flow and winds aloft increase Tuesday night into Wednesday, and this will lead to stronger Santa Ana winds along with continued very low humidities."
The NWS warned that fire conditions will worsen Wednesday as compared to Tuesday, but the agency does not anticipate issuing any fire weather watches or red flag warnings.
"The offshore winds will weaken considerably Thursday before turning onshore, leading to a significant cooling trend starting Friday and continuing into the weekend," according to the NWS.
