A flash flood warning was issued across parts of San Bernardino County Thursday afternoon, according to the National Weather Service.
An alert from the agency warned of flooding that’s expected to affect cities including San Bernardino, Fontana and Moreno Valley until 1:30 p.m. It tells residents to avoid walking or driving through rising flood waters and seek higher ground.
Up to 1.7 million people and 394 schools could be impacted by the flash flooding, officials said. The San Bernardino Unified School District issued a message to parents and guardians saying students who live areas being monitored by law enforcement would need to be picked up or remain sheltered at the campus.
“Students who live in close proximity to the police activity will remain safe at school in our CAPS program unless they are picked up from school by a parent or guardian,” the written message reads.
Across Orange and San Bernardino counties, rainfall totals were reaching up to 10 inches in 5 days in some areas, officials said. The foothills in both counties saw especially high levels of rainfall over the last 24 hours.
“Moderate to heavy rain” is expected to move toward areas of western Riverside and southwest San Bernardino counties seen designated in a map tweeted by the National Weather Service.
Mountain coastal slopes of San Bernardino were soaked with 3 to 6 inches of rain in just the past several hours, officials said.
Meanwhile, the San Bernardino County Sheriff’s Department warned of driving risks along flooded streets, reminding drivers to pay attention to road signs.
