...Localized flooding possible for California late Thursday into the
weekend...

.California...
Locally heavy rainfall over portions of northwestern California will bring
the potential for urban flooding this evening and tonight.

Moderate to locally heavy rainfall will be possible late Thursday into the
weekend over coastal regions of California. In general, antecedent
conditions over the area will mitigate non-urban flooding. However,
localized heavy rain rates may periodically overwhelm soils, resulting in
runoff and rises on local streams. Additionally, heavy rainfall near recent
burn scars will result in flash flooding and debris flows.

.Arizona...
The same weather system that is impacting California starting late Thursday
will shift eastward into Arizona, bringing a period of moderate to locally
heavy rainfall to the area. The focus of the rainfall (and any hydrologic
impacts) will mostly be on the Mogollon Rim on Saturday and Sunday. Snow is
mainly expected at the higher elevations, and any potential hydrologic
impacts are mainly going to be urban and small stream in nature. The
inclusion on the FHO is not warranted at this time, but trends will be
monitored.
