While the heavy rain has ended across California and the Four
Corners region, moisture from the Gulf of California will continue
to stream into the Southwest and Southern Plains, producing
showers and thunderstorms, some severe, today. A Slight Risk
(level 2 of 4) of excessive rainfall is in effect for portions of
the southern New Mexico and far western Texas today, shifting to
the Southern Rockies and the Central and Southern High Plains on
Saturday and Sunday, where localized flash flooding is possible.
River flooding will continue in parts of southwest Colorado,
northern New Mexico, and northern Arizona as runoff works
downstream.

This will be the last Storm Summary issued by the Weather
Prediction Center for this event. Please refer to your local
National Weather service office for additional information.
