result in scattered to numerous showers and thunderstorms capable
of producing heavy rainfall from late tonight through late
tomorrow night. Rain totals of 1 to 2 inches are expected with
the stronger storms with isolated amounts over 2 inches possible.
Areas that received substantial rainfall over the previous few
days will be more susceptible to flash flooding. This rainfall
will result in faster response in washes, creeks, and storm
drainages.
