* 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. Do not forget to plan for you pets and animals.

Please never drive across flooded waters and roadways, especially
flowing water. Most people who are killed or injured during floods
are attempting to drive through flooded waters. Turn around, don`t
drown!
