Today marks the beginning of the Atlantic hurricane season, with forecasters predicting one of the most active seasons on record. Multiple outlets are confident that this season will be above average, with NOAA's official forecast calling for up to 25 named storms, compared to the average of 14. Of these storms, 13 could potentially become hurricanes, while the average is 7.
The forecasters attribute the expected intensity of the season to the presence of La Nina, a cooler ocean circulation in the Pacific. La Nina's influence on the jet stream can redirect storm paths to the north, reducing wind shear in the Atlantic and creating favorable conditions for storm development.
Another significant factor contributing to the forecasted active season is the unusually warm ocean temperatures. The ocean temperatures are currently 3 to 5 degrees above average, providing ample fuel for stronger storms. This warming trend is linked to climate change, as oceans absorb 90% of the heat from greenhouse gas emissions, resulting in more intense and moisture-laden storms.
Climate change's impact on hurricanes includes heavier rainfall, higher storm surges due to sea level rise, and the potential for more costly and destructive storms. The increased intensity and frequency of storms can lead to higher insurance costs and greater damage inland.
Early Season Heatwave Sweeps Across Western U.S.
Alongside the active hurricane season, the Western United States is experiencing an early-season heatwave. Excessive heat watches have been issued for parts of California and Nevada, including Las Vegas, where temperatures are expected to soar into the triple digits.
Temperatures in Phoenix and Las Vegas are forecasted to reach 105 degrees, significantly above the average for this time of year. Sacramento and Denver are also expected to experience temperatures well above normal, posing risks of heat-related illnesses for vulnerable populations.
The unseasonably high temperatures are a cause for concern, as residents and infrastructure may not be adequately prepared for the extreme heat. The combination of an active hurricane season and early heatwave underscores the importance of climate resilience and preparedness in the face of changing weather patterns.
