LOS ANGELES (AP) - California State University, San Bernardino, has closed its campus because of danger from Santa Ana winds sweeping parts of Southern California.

Campus spokesman Joe Gutierrez says classes ended Friday morning and some 17,000 students were told to go home or to not show up. No wind damage is reported but Gutierrez says there's concern because the campus sits in an area where wind gusts could hit 50 mph or more.

The hot, dry winds have prompted red-flag warnings of extreme fire danger for mountains and valleys through Saturday afternoon. Gusts of nearly 60 mph are reported in Malibu.

The weather service also warns of high surf, reaching 8 feet in the Los Angeles area Friday night and up to 14 feet farther north.
