Hot tropical weather spawned thunderstorms that sent flood waters rushing through the Acton area Thursday, prompting the hoist rescue of a man whose pickup truck became stranded.
National Weather Service forecasters had issued a flash flood watch for the San Gabriel Mountains and the Antelope Valley as “copious amounts of monsoonal moisture” streamed across Southern California throughout the day.
The flooding in Acton was caused by an intense 30-minute midafternoon downpour that also inundated parts of the Antelope Valley (14) Freeway and Sierra Highway.
The hoist rescue occurred at 5:20 p.m. in the area of Syracuse Avenue and Crown Valley Road, where flood waters swamped several properties.
Flooded and possibly undermined tracks near Aliso Canyon Road also brought at least one Metrolink train to a halt in the area.
An NWS statement had warned that flash flooding and debris flows would be a threat especially in areas previously denuded in wildfires.
Temperatures around 100 degrees were reported in some valley and desert locations.
