Hydrologic Outlook

...Flood Potential Outlook for quick river rises, main stem river
flooding, and the potential for snow melt flooding on rivers and
streams in the following counties in California...Modoc...Siskiyou
and in Oregon...Coos...Curry...Douglas...Jackson...Josephine...Klamath...Lake...

.At atmospheric river will bring a good chance for periods of heavy
precipitation over Coos, Curry, and Western Siskiyou Counties Sunday
through Tuesday and possibly longer. A front will likely stall over
the forecast area late this weekend with waves of heavier precipitation
moving through. The front will push through the area by early or the
middle of next week. 4 to 8 inches of rainfall are possible at the coast.
Confidence is low on how much rainfall and timing of heaviest rainfall, but
recent data have increased the chance for significant river rises and
flooding enough to warrant this outlook.

Farther east, there is higher uncertainty in terms of flooding potential.
It`s unknown how far inland the heaviest precipitation will extend and for
how long. However, periods of heavy precipitation are possible here as well,
and given how much snowpack is in the mountains, an extended period of heavy
rain on snow would result in flooding of small creeks and streams as well
as significant rises on main stem rivers.

A flood potential outlook is issued when there is the potential for
significant rises or flooding along rivers and streams.

The exact scenario for flooding remains uncertain. This product will
be updated as necessary. Watches and warnings may be issued by the
National Weather Service if this situation worsens.
