* Interior Northern California will experience another significant
uptick in flooding problems starting late Sunday Night and
continuing through Monday Night as an intense Atmospheric River
type storm arrives.

* Our entire region has saturated soils and many flooded areas
already...this will enhance the impact of additional heavy rains.

* Additional stress will be placed on levees, rivers, creeks, and
streams.

* We may see flooding in locations which haven't been impacted in
many years.

* We are strongly advising all residents in interior Northern
California to be prepared for flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be prepared to evacuate if flooding should affect your area. Gather
a "go bag" with important items like medications and hard to replace
documents. Don't forget to plan for your pets and animals.

Please never drive across flooded waters...especially flowing water.
Most people who are killed or injured during floods are attempting
to drive through flooded waters.
