* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...A portion of Southwest California, including the following areas, Apple and Lucerne Valleys, Coachella Valley, Orange County Coastal Areas, Orange County Inland Areas, Riverside County Mountains, San Bernardino County Mountains, San Bernardino and Riverside County Valleys-The Inland Empire, San Gorgonio Pass near Banning and Santa Ana Mountains and Foothills. * WHEN...Through this evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Mud and debris flow are possible near and in burn scars, including the Airport, Bridge and Line burn scars. * ADDITIONAL DETAILS... - An Atmospheric River will bring widespread moderate to heavy rain to the region today. The heaviest and most widespread rain is expected this morning through evening. Peak rainfall rates of 0.50 to 1 inch per hour are expected. There is a potential for locally heavier hourly rainfall rates to develop with convection embedded in the main rain band or in thunderstorms after the main band passes. Isolated heavy showers could continue into Thursday but impacts from any additional rain are expected to be more localized. Snow levels are expected to remain above 8000 feet during period of heaviest precipitation bringing a heightened risk of mud slides, debris flow, and areas of flash flooding in the San Bernardino county mountains. - https://www.weather.gov/safety/flood
Summary
The ideal streamflow range for this segment is between 500 and 1,500 cfs, which typically occurs during the spring snowmelt or after a heavy rain event. This segment is rated as Class III-IV, meaning there are moderate to difficult rapids that require experienced paddlers. The segment is approximately 7 miles long and includes several notable rapids, including "Frog's Leap," "S-turn," and "Pinball." Obstacles include boulders, drops, and narrow channels that require precise maneuvering.
When planning a trip on the Whitewater River, it is important to be aware of specific regulations in the area. Permits are required to enter the San Gorgonio Wilderness, which includes the end of this segment. Additionally, there are restrictions on the use of motorized equipment and camping along the river. Visitors should also be mindful of the potential for flash flooding during the summer months.
