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 will be in effect from 6 a.m. Tuesday to 3 p.m. Wednesday for the San Bernardino and Riverside County valleys, the Inland Empire and the San Bernardino County mountains — including the cities of 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.

NWS forecasters warned that the winds will make driving treacherous for high-profile vehicles, while also bringing down tree limbs and potentially knocking out power.

The strongest winds will be near and below the Cajon Pass, according to the weather service.

“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,” according to the NWS.

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.
