NOAA & CSU Update Their 2021 Atlantic Hurricane Season Outlooks

5 Aug 2021, 7:34 pm

The National Oceanic and Atmospheric Administration has released its updated 2021 Atlantic Hurricane Season forecast. The agency is still predicting an above-average season with 15-21 named storms and 7-10 hurricanes. The number of major hurricanes, Category 3 and above, remains the same at 3-5 expected.

This is a slight change from the initial forecast back in May of 2021, of 13-20 named storms and 6-10 hurricanes forecast. There is a 65% chance of an above-average Atlantic Hurricane Season, and only a 10% chance of a below-normal season.

Colorado State University updated its forecast on Thursday August 5th to included 18 named storms, and 8 hurricanes. This is a slight decrease from an earlier forecast update in July which called for 20 named storms and 9 hurricanes.

This season is expected to be above average for a couple reasons. According to Matthew Rosencrans, lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, “ENSO-neutral and La Nina support the conditions associated with the ongoing high-activity era.” Warm sea-surface temperatures will also allow for enhanced storm activity.

The peak of Atlantic Hurricane Season is typically in mid-September and we are anticipating more activity in the coming weeks and month in the Ocean.
