Flash flood warnings were issued early Tuesday afternoon for wildfire burn areas in Riverside and San Bernardino counties.
The warnings, expected to expire later Tuesday afternoon, were issued due to the possibility of heavy rain in the Apple and El Dorado burn areas.
The Apple Fire burned about 33,000 acres in the summer of 2020 in the Cherry Valley area of Riverside County. The El Dorado Fire near Yucaipa, east of San Bernardino, and the San Gorgonio Wilderness Area burned more than 22,700 acres later that year.
The National Weather Service warning indicated heavy rainfall that could cause flash flooding of streams, creeks and ditches in the burn scar area. Debris flow is possible across roads.
