West Coast States Brace for Warm and Wet Weather as Atmospheric River Approaches
The Pacific Northwest is poised for a drenching and unseasonably warm weekend as an atmospheric river, a long, narrow region in the atmosphere laden with tropical moisture, makes its way towards the region. The National Weather Service (NWS) has issued a Winter Weather Outlook for Oregon and Washington, urging residents to prepare for heavy rain and potential flooding.
A Warm and Wet Weekend in Store
Saturday will usher in persistent rain throughout the greater Portland and Vancouver areas, courtesy of the approaching atmospheric river. Temperatures, defying January norms, will soar into the upper 50s Fahrenheit, creating a stark contrast to the usual chilly conditions. Forecasters predict rain accumulation to reach approximately 1.35 inches by day’s end.
Sunday will offer a brief respite from the incessant downpour, with drier and slightly warmer conditions emerging late Saturday night into Sunday morning. However, the reprieve will be short-lived, as temperatures are expected to climb even higher, reaching the low to mid 60s Fahrenheit in the Willamette Valley, potentially challenging record-breaking highs. Mostly cloudy skies will prevail throughout the day.
Monday will bring continued mild weather, with temperatures hovering in the low 60s Fahrenheit and clear skies and sunshine. This brief interlude of drier conditions will provide temporary relief from the wet spell.
Impact on Snowpack and Water Resources
The warmer temperatures and higher elevation rain will accelerate snowmelt in the Cascade Mountains, potentially affecting ski resorts and winter recreation activities. Snow levels are forecast to rise above 6,500 feet this weekend, leading to a reduction in snowpack. While the warmer weather may provide a temporary reprieve, cooler temperatures and the return of moisture next week will replenish the snowpack, a crucial source of water resources and summer water supplies.
Precautionary Measures for Residents
Residents in flood-prone areas are strongly advised to take necessary precautions and monitor water levels closely. Drivers should exercise caution on wet roads and be prepared for reduced visibility due to heavy rain. Outdoor enthusiasts should be aware of changing weather conditions and adjust their plans accordingly.
Looking Ahead: A Gradual Return to Seasonal Norms
Later next week, a gradual cooling trend is expected, bringing temperatures closer to seasonal norms. The NWS forecasts a return to wetter conditions, with potential rain and snow in the region.
