* 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

Tahoe will continue to rise, but is likely to remain below flood
stage. Rock and mud slides are also possible.
