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. If you live in mountain
communities, clear drainage systems of snow or other debris that may
have accumulated over the winter.
Near record high temperatures through Sunday will bring
significant streamflow rises, especially for snow covered terrain
below about 8000 feet. Rises will likely increase daily through the
