Dec. 20 (UPI) -- A flood watch is in effect in the greater Portland area and large portions of western Oregon and southwestern Washington as rainy conditions continue.

The National Weather Service issued the flood watch on Saturday morning, which is in effect until 4 p.m. PST and follows a week of heavy rainfall, Oregon Live reported.

Local flooding is likeliest in urban areas and in locations with relatively little water drainage, and the day's forecast calls for an 80% chance of rainfall during the morning hours.

The Sandy and Clackamas rivers are especially vulnerable to flooding, and at least one person has died as many roads in western Oregon became covered by landslides and other weather-related damage, according to OPB.
