The numbers are in for November and, despite the cold snap at the end of the month, the mean temperature for November was still the warmest of the past four years and a full degree above the long-term average (LTA) for the reference period 1981-2010. Rainfall turned out to be slightly higher than the LTA and soil temps quite a bit higher than prior years.
Basically, it's all a bit unpredictable. No tropical cyclones formed in the Atlantic basin during November. However, Tropical Storm Wanda continued from the end of October through the first seven days of November. Based on a 30-year climatology (1991-2020), a tropical storm forms in November every one to two years.
Overall, NOAA reports that the 2021 Atlantic hurricane season featured above-normal activity. Twenty-one named storms formed, of which seven became hurricanes and four became major hurricanes - category 3 or higher. Even though it seemed quiet in the Atlantic this year, it really wasn't - but it was definitely not as wild as last year.
