Flood warnings and high wind advisories have been issued by the National Weather Service for Dec. 7, 2015. According to The Weather Channel, the advisories are for Northwestern (NW) Oregon and Southwestern (SW) Washington.
Flood Warning For Urban Areas and Small Streams
The flood warning is in effect until Dec. 7, 2015, at 2:30 p.m. PST for the following counties:
- NW Ore., Eastern Polk County
- NW Ore., Western Clackamas County
- NW Ore., Western Multnomah County
- NW Ore., Yamhill County
- NW Ore., Washington County
- NW Ore., Columbia County
- NW Ore., Marion County
- SW Wash., Clark County
- SW Wash., Cowlitz
The National Weather Service alerts people in these areas to take precautionary measures and be prepared. The excess runoff from the heavy rainfall can cause ponding of water in urban areas and on highways. Streets and underpasses may experience the same pooling of water. Areas with poor drainage and low-lying spots will also likely experience pooling.
Do not attempt to travel on flooded roads. Find alternative routes. Follow all warning signs. Only a few inches of swiftly flowing water could carry vehicles away. Moreover, the deep waters could cause damage to a vehicle’s undercarriage and exhaust system as well. Water can also create slippery driving conditions in places where the water is not deep.
Wind Advisory 20-30 mph With Gusts Up to 40 mph
The wind advisory is in effect until Dec. 7, 2015, at 6:00 p.m. PST, and is predicting winds coming from the south in NW Ore. and SW Wash.

The National Weather Service advises motorists in high-profile vehicles, such as campers, motorhomes, semi-trucks with trailers, and any other large vehicle affected by high winds, to use caution when traveling across exposed bridges and overpasses.
Power outages are possible due to downed electrical lines. Do not touch a downed electrical line. Call local emergency services to enable them to secure the area and protect the public.
Downed trees and limbs are possible. When traveling, be on alert for blocked or damaged roadways from fallen trees.
