PRECAUTIONARY/PREPAREDNESS ACTIONS…

You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop. Given the aforementioned
rainfall amounts expected this weekend, river levels will be rising
quickly. Most rivers have anywhere from a 30-50% chance of reaching
at least minor flood stage, except the mainstem Columbia and
Willamette Rivers which is less than 10% chance. Coastal rivers
however have a 40-60% chance of reaching minor flood stage and
20-30% chance for reaching major.
