Santa Ana Winds Lash Pass Area, Storm And Cooler Weather Forecast: NWS

BANNING, CA — Thursday's Santa Ana winds and low relative humidity increased wildfire risks throughout the region, as evidenced by an early morning blaze in the Eastvale and Jurupa Valley areas.

The National Weather Service posted a wind advisory was in effect through 2 p.m. Thursday. Cooler weather is predicted through the weekend, and rain may be possible within a week, according to meteorologist reports.

The previous Santa Ana wind event spanned three days, beginning Halloween weekend and concluding early last week. Conditions contributed to the rapid spread of a blaze north of Aguanga that consumed nearly 2,500 acres and damaged or destroyed over a dozen structures, including three homes. On Thursday morning, a wind-whipped wildfire forced a temporary closure of the I-15 freeway near Eastvale and Jurupa Valley.
