2020 Atlantic Hurricane Season Outlook

After experiencing two named storms before hurricane season officially started, NOAA’s 2020 Atlantic Hurricane Season Outlook predicts an “above-normal” season to be most likely. Specifically, the outlook indicates a 60% chance of an above-normal hurricane season, with a chance of the season being extremely active. As a result, the 2020 Atlantic hurricane season could set a record for having five consecutive above-normal seasons in a row.

Similar to the 2019 Atlantic hurricane season, the factor that plays the largest role in the expectation of high-activity this season is the warm sea surface temperatures. In addition, weak trade winds and an enhanced West African monsoon season are factors that will increase hurricane activity in the Atlantic.

2020 Eastern Pacific Hurricane Season Outlook

This year, NOAA’s eastern Pacific Hurricane Season Outlook predicts a combined 75% chance for a near- or below-normal season.

The combination of slightly below-average sea surface temperatures across the eastern Pacific, and above-average sea surface temperatures across the Atlantic are often associated with near- or below-normal hurricane activity for the eastern Pacific hurricane region. Due to these seasonal trends, experts believe La Niña is most likely.

The 2020 outlook calls for a 70% probability for each of the following ranges of activity:

  • 11-18 Named Storms
  • 5-10 Hurricanes
  • 1-5 Major Hurricanes
  • Accumulated Cyclone Energy (ACE) range of 60%-135% of the median.
