Washington State Poised to Break Record for Warmest December Again

Washington State is on track to experience its warmest December on record, surpassing the previous benchmark set just last year. Meteorologist Steven Reedy from the National Weather Service reported that the average temperature for December 2023 is expected to reach 45.9 degrees Fahrenheit, edging past the record of 45.5 degrees established in the same month last year.
Exceptional Weather Patterns and Impact
This December has brought substantial rainfall and is marked as one of the wettest months for the Seattle area. A significant factor contributing to this deluge has been the occurrence of three atmospheric rivers, which have led to severe flooding in some parts of the region. This is a noteworthy phenomenon, especially when considering that the preceding fall was characterized by severe drought conditions throughout the state.
Rainfall and Drought Recovery
As of late December 2023, Washington is just 0.18 inches short of its average annual rainfall. According to Deputy State Climatologist Karin Bumbaco, the state had been contending with one of its driest years on record, particularly affecting the Yakima Basin, which has faced drought for three consecutive years. The basin recorded some of its lowest water levels since monitoring began in 1971.
- Current Average December Temperature: 45.9°F
- Previous December Record: 45.5°F
- Total Rainfall Deficit: 0.18 inches from annual average
- Drought Duration in Yakima Basin: Three years
- Lowest Water Levels Recorded Since: 1971
Future Outlook
The recent rainfall provided a much-needed boost to the water storage levels in the Yakima Basin, albeit the rapid influx of water raised concerns about flooding. Bumbaco emphasized the importance of gradual rainfall to mitigate flood risks and ensure sustainable water resource management.
Despite the challenges posed by fluctuating weather patterns, the current conditions are a reminder of the complex relationship between drought and flooding in Washington State. As the month progresses, residents and officials will remain vigilant in monitoring the weather and its impacts on local ecosystems and water supplies.
