* A portion of Northwest Oregon, including the following areas,
  Central Columbia River Gorge and Western Columbia River Gorge.

* As of Saturday afternoon, rainfall rates are increasing in the
  Columbia River Gorge. 1 to 2 inches of rain are expected this
  afternoon, with an additional 2 to 4 inches expected Saturday
  evening through Saturday morning.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.

Landslides and debris flows are also possible during this heavy
rain event. People, structures and roads located below steep
slopes, in canyons and near the mouths of canyons may be at
serious risk from rapidly moving landslides.

Monitor nearby streams, creeks and storm water drainages for
blockage or sudden rises. Signs that a flash flood or debris flow
may be imminent include: Intense heavy rain and rapid increase in
water levels in creeks, possibly accompanied by increased
muddiness, a sudden decrease in creek water levels even though
rain is still occurring or has only recently stopped, a faint
rumbling sound or sound that increases in volume and sounds of
trees cracking or boulders knocking together.

Be aware that bursts of intense rainfall may be particularly
dangerous, especially after longer periods of moderate steady
rainfall. If you are in areas susceptible to landslides and
debris flows, consider leaving if it is safe to do so. Remember
that driving during an intense storm can be hazardous. If you
remain at home, move to a second story if possible. Staying out
of the path of a flash flood or debris flow saves lives.

Stay alert and awake. Many flash flood and debris flow fatalities
occur when people are sleeping. Watch roads for collapsed
pavement, mud, fallen rocks, and other indications of possible
flash floods or debris flows. Listen to a NOAA Weather Radio or
portable, battery-powered radio or television for warnings of
intense rainfall. If you observe or hear warning signs
immediately move out of the path to higher and stable ground,
inform affected neighbors and report to 9 1 1 and the National
Weather Service. If escape is not possible curl into a tight ball
to protect your head. Do not drive across a flooded road or into
shallow debris even though it may look passable.
