FLASH FLOOD POTENTIAL INDEX FOR EXTREME SOUTHWESTERN CALIFORNIA Monsoonal moisture will be increasing through midweek, providing the fuel for scattered shower and isolated thunderstorm development over most of the area. Moderate easterly flow should limit the flooding potential, and clouds may limit instability at times as well. As steering flow weakens, and moisture decreases aloft later on Wednesday…the chance for stronger, slow moving thunderstorms with heavy rain and possible flash flooding will increase into Thursday.
