Moisture from a west northwestward moving tropical storm which dissipated west of central Baja California generated up to two inches of rainfall in the deserts and mountains starting on 7/28 and ending on 7/30. This occurred during the El Niño of 1957-58. On this day a thunderstorm hit the Barton Flats and Forest Home (now Forest Falls) area with two inches of rain. Several walls of mud rolled off fire-denuded hills onto the road in several places along the highway in Barton Flats and Forest Home. Five cars were trapped.
