* WHEN…Through late tonight.
* IMPACTS…Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Creeks and streams may rise out of their banks. Street flooding
and flooding of creeks and rivers are possible.
* ADDITIONAL DETAILS…
– The primary concern is the potential for river flooding.
Heavy rain may also result in landslides in areas of steep
terrain. Debris flows over and near the recent burn areas in
the north Oregon Cascades cannot be ruled out either, however
the potential appears to be low as the axis of heaviest rain
should be north of the burn areas.
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.
