Atmospheric River to Drench Portland and Surrounding Areas with Heavy Rain
An atmospheric river has hit Oregon, bringing significant rainfall to the Portland area. From Wednesday until early Saturday, the region is expected to receive around 4 inches of rain. The National Weather Service (NWS) has issued warnings, highlighting that the Coast Range may see up to 9 inches of precipitation, particularly near Tillamook.
Projected Rainfall and Flood Risks
According to Thomas Schuldt, a meteorologist with the NWS in Portland, the amount of rain predicted is concerning. The Oregon Cascades north of Lane County could receive between 4 to 7 inches through Saturday. However, snow levels are not expected to go below 4,000 feet.
Flood Watch Issued
The NWS has placed a flood watch in effect for the Inner Portland Metro from Thursday morning until early Saturday. Key areas at risk include:
- Pudding River at Aurora
- Johnson Creek
These rivers are forecasted to reach minor flood stages. Schuldt indicates that many smaller streams and rivers will likely experience rises as well, urging drivers to avoid flooded roads.
Potential Landslides and Additional Storms
There’s a slight risk of landslides due to the heavy rainfall. The atmospheric river, which originates in the Pacific Ocean near Hawaii, is expected to shift north and south across Washington and Oregon over the next few days, affecting rainfall intensity.
Future Weather Forecast
Rain is anticipated to lessen by Saturday, but forecasts suggest another atmospheric river could approach early next week. Currently, it appears that Oregon will be on the southern edge of this storm, with the most significant impacts likely in Northwest Washington and British Columbia.
Should Oregon avoid the storm, temperatures in both Portland and Eugene could reach unusually high levels, potentially hitting 70 degrees early next week. This weather variability indicates notable changes over the coming days.
