When: From late tonight through Friday afternoon.
Impacts: Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Low-water crossings may be flooded.
Additional Details: - Extensive heavy rainfall in the San Bernardino Mountains that resulted in instances of flash flooding and debris flow in the mountains and adjacent drainages in the northern Inland Empire and High Desert yesterday have saturated the soils and drainage banks. An additional 1-3 inches (and locally up to 4 inches) of rainfall is expected in the mountains tonight. While rainfall rates will be generally lighter than yesterday (closer to 0.2-0.5"/hr), the saturated soils and drainage banks will likely be more susceptible to flash flooding with the additional rainfall. Snow levels will generally be around 7500-8000ft for this secondary round of precipitation tonight and Friday. - Https://www.weather.gov/safety/flood
