Continued Heavy Rain

Continued heavy rain starting tonight through Wednesday will bring some flooding in many areas surrounding Clark County.  The heaviest of the rains will begin this evening over a 6 hour period of time.  Most of the rain will be along the coast, in Oregon, and Willamette Valley,  however some potential Urban flooding is possible in our area.  Please make sure you are aware Storm Drains in your area to help reduce this risk.

Below is an overview of the next couple days:

 Heavy Rain (late Monday night – early Wednesday)
  •  .5 to 1” Monday 4 am to Tuesday 4 am (coast
  • 1-2” Tuesday 4 am to Wednesday 4 am
  • Total 1-3 inches in two days

Potential Flooding (Tuesday and Wednesday) for areas outside of Clark County
Some gusty Winds. 
  • Broken Tree Limbs
  • Isolated power disruptions possible
  • Inland 20-25 mph, gusts 30-40 mph
Urban flooding and some roadway flooding due to clogged drains and leaves.
Always landslide potential with saturated grounds (steeper and less stable slopes)

This is a very moisture rich system, known as the Pineapple Express (Atmospheric River)which is aimed towards Pacific NW once again.  As a reminder if you do come along flooded roads, remember to turn around.. don't drown!

The following Video also gives insight into the storm.  

More information on this system can be found NWS Portland.
