The Lake Wobegone Hurricane Forecast

 Always above average. WUWT, NOAA Predicts Above-Normal 2022 Atlantic Hurricane Season

Forecasters at NOAA’s Climate Prediction Center, a division of the National Weather Service, are predicting above-average hurricane activity this year — which would make it the seventh consecutive above-average hurricane season. NOAA’s outlook for the 2022 Atlantic hurricane season, which extends from June 1 to November 30, predicts a 65% chance of an above-normal season, a 25% chance of a near-normal season and a 10% chance of a below-normal season.

Although that's "above average," it's not a lot above average, and there's still a pretty decent chance that the season will be average or below.

For the 2022 hurricane season, NOAA is forecasting a likely range of 14 to 21 named storms (winds of 39 mph or higher), of which 6 to 10 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). NOAA provides these ranges with a 70% confidence.

“Early preparation and understanding your risk is key to being hurricane resilient and climate-ready,” said Secretary of Commerce Gina M. Raimondo. “Throughout the hurricane season, NOAA experts will work around-the-clock to provide early and accurate forecasts and warnings that communities in the path of storms can depend on to stay informed.”

The increased activity anticipated this hurricane season is attributed to several climate factors, including the ongoing La Niña that is likely to persist throughout the hurricane season, warmer-than-average sea surface temperatures in the Atlantic Ocean and Caribbean Sea, weaker tropical Atlantic trade winds and an enhanced west African monsoon. An enhanced west African monsoon supports stronger African Easterly Waves, which seed many of the strongest and longest lived hurricanes during most seasons. The way in which climate change impacts the strength and frequency of tropical cyclones is a continuous area of study for NOAA scientists.

The siege of active Atlantic hurricane seasons will continue for yet another year, the National Oceanic and Atmospheric Administration predicted Tuesday. In its annual seasonal outlook, the agency forecast the seventh straight above-normal Atlantic season, with 14 to 21 named storms — compared with 14 in an average year — and three to six major hurricanes, rated Category 3 or higher.
