...FLASH FLOOD WATCH IN EFFECT FROM SATURDAY MORNING THROUGH
SUNDAY AFTERNOON...

The National Weather Service in Portland has issued a

* Flash Flood Watch for a portion of Northwest Oregon,
  specifically for the Eagle Creek burn area in the Western and
  Central Columbia River Gorge.

* From Saturday morning through Sunday afternoon.

* Rain is expected to begin late tonight and Saturday morning.
  Heavy rain is expected Saturday afternoon through early Sunday.
  The rain is expected to decrease significantly Sunday
  afternoon.

* Total rainfall amounts for the Eagle Creek burn area through
  Sunday are forecasted to be 4 to 7 inches and could possibly
  reach 8 or 9 inches in some areas of the burn. This would be
  enough rainfall to likely cause flash flooding, landslides, and
  debris flows.

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 possible during this flash flood
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.
