Flood Watch this Weekend

The National Weather Service has issued a flood watch for much of the Pacific Northwest including Columbia County. Click here to read the flood watch statement

Two significant batches of rain will pass through the area.

Total rain levels from these systems are expected to be:

  • 5-9” with locally higher totals possible north coast, Coast range, south Washington Cascades
  • 3-6” central OR Cascades
  • 2-3.5” inland
Sharp river rises expected to push several rivers to flood stage Saturday night into Sunday.

The break in rainfall between storms is not as long as previously anticipated

Flooding concerns increased north OR coast, south WA Cascades

Wind gusts Saturday afternoon through Sunday morning –45 -55 mph coast, 15-25 mph inland

Hazards to proactively prepare for:
o Heavy rain (North coast and mountains)
o River flooding, many rivers near bankfull
o Small stream flooding, with urban ponding likely
o Landslides and debris flow potential, especially Coast Range

Sandbag materials are available at Columbia County Road Department
(1054 Oregon Street, St. Helens between the Animal Shelter and the Road Department) and St. Helens Public Works (984 Oregon Street, St. Helens). It is a "make your own" system so come with that expectation if you do stop by to get sand bags.

Sandbags are available at the County Road Department 7 days a week. Citizens are asked to be considerate and take only between 10 and 15 bags per trip.
