July 23, 2019, San Bernardino ____

The California Department of Transportation (Caltrans) is alerting the traveling public that the National Weather Service (NWS) has projected an influx of monsoonal moisture which may bring the chance of showers and thunderstorms throughout this week, particularly in the afternoon and early evening. 


Thunderstorms that affect the Cranston Burn Scar (State Routes 74 and 243) could produce rainfall rates of a quarter inch to three-quarter inches per hour. The thresh hold for debris flows is 1.1 inch of rainfall per hour. 


Caltrans is alerting motorists that SR 74 between Hemet and Lake Hemet is subject to closure (for escorts) in the event that debris flows, or other conditions make the roadway unsafe for travel. This also includes the open section of SR 243 between Idyllwild and Lake Fulmor. Motorists should always be prepared and us extreme caution when driving on desert and mountain roadways during storm events.
