ESFPQR
A series of storms will bring ample precipitation to Northwest
Oregon and Southwest Washington this week. Of particular concern is
the potential for heavy rain Tuesday night through Friday morning,
which could result in some flooding for area creeks and rivers.
The latest projections of the most likely amounts for storm total
precipitation are a little lower today than yesterday's forecasts.
Amounts range from 3.5 to 6 inches for the Coast, Coast Range, and
Cascades, with 1.5 to 3 inches for inland valley locations,
including Portland, Salem, and Eugene. Upper end projections, with
about a 10 percent chance of occurring, range from 6 to 10 inches
for the Coast, Coast Range, and Cascades, and 2.5 to 3.5 inches for
inland valleys. Snowmelt in the Cascades from 2000 to 4000 feet
elevation could add runoff, although runoff from heavy rain would be
the main driver for any flooding that occurs.
Rivers will rise starting Wednesday. Small streams and
fast-responding rivers could see flooding as early as Wednesday
night or Thursday, with slow-responding rivers potentially flooding
by this weekend. Heavy rainfall will also cause water ponding in low
lying areas and other areas of poor drainage.

warnings, or advisories that may be issued for this event.
