Washington State's Unseasonable Warmth: A Record-Breaking December
Washington state is on the cusp of experiencing its warmest December on record, surpassing the previous record set just last year. According to Steven Reedy, a meteorologist with the National Weather Service, the average temperature this month is projected to reach a staggering 45.9 degrees Fahrenheit. This is a significant increase from the 45.5 degrees recorded in 2023.
Despite the La Niña winter forecast, which typically brings cold and wet conditions to the Pacific Northwest, December has been unusually wet. The Seattle area, in particular, received above-average rainfall, largely due to three atmospheric rivers that caused severe flooding in the region. This contrast between the forecast and the actual weather highlights the unpredictability of climate patterns.
The state's recent drought conditions, which had Washington on track for the fifth driest year on record, have been alleviated by the recent rainfall. However, the Yakima Basin, which has been grappling with drought for three years, still faces challenges. This fall, the basin experienced some of the lowest water levels since 1971, underscoring the ongoing impact of drought.
The atmospheric rivers that caused flooding have helped restore the state's annual rainfall levels. As of now, Washington is just 0.18 inches shy of the average annual rainfall. While this rainfall is beneficial, Karin Bumbaco, the deputy state climatologist, notes that a more gradual and controlled amount of rainfall would have been preferable for the Yakima Basin to avoid flooding. Nonetheless, the water has significantly increased storage and reduced long-term precipitation deficits.
This record-breaking December serves as a stark reminder of the complex interplay between climate patterns and local conditions. As Washington state continues to experience unseasonable warmth, it underscores the need for ongoing climate monitoring and adaptation strategies to ensure the well-being of both the environment and its residents.
