Breaking at this hour in the desert area of California, in Palm Springs, which may have caused one fatality, according to early reporting:

A massive boom that rocked downtown Palm Springs on Saturday around 11 a.m. appears to be a car explosion near the American Reproductive Centers clinic on North Indian Canyon Drive at East Tachevah Drive, Palm Springs police said around noon
