...INCREASED FLOOD RISK AS AN ATMOSPHERIC RIVER IMPACTS THE
REGION THROUGH LATE MONDAY...

.A potent storm will bring another round of heavy rainfall to the
greater San Franciso and Monterey Bay areas beginning by late
this afternoon into late Monday. Additional rainfall on already
saturated soils will increase the threat for flash flooding,
flooding of area creeks, streams and low lying, poorly drained
areas across the region. The threat for rock/mud slides and
shallow landslides also exists as well as increased likelihood for
downed trees, power lines and damage to or washed out roadways.
