NOAA forecasts another above average hurricane season

NOAA forecasts another above average hurricane season



25 May 2022

The ongoing La Niña event and above-average Atlantic Ocean temperatures have set the stage for an above average hurricane season. This would make it the seventh consecutive year of above average activity, according to an outlook from the US National Oceanic and Atmospheric Administration (NOAA).

Forecasters at NOAA’s Climate Prediction Center, a division of the National Weather Service, predict 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.

NOAA is forecasting a likely range of 14 to 21 named storms (winds of 39 mph (63 kmh) or higher), of which 6 to 10 could become hurricanes (winds of 74 mph/119 kmh or higher), including 3 to 6 major hurricanes (category 3, 4 or 5; with winds of 111 mph/179 kmh or higher). NOAA provides these ranges with a 70% confidence.

NOAA’s outlook is for overall seasonal activity and is not a landfall forecast. The hurricane season extends from June 1 to November 30.

In the North Atlantic, and north eastern Pacific basins, WMO’s Regional Specialized Meteorological Center Miami (the US National Hurricane Center) is responsible for tropical cyclone forecasting, including for marine-related hazards.

The hurricane seasons in 2020 and 2021 were exceptionally active and both exhausted the regular names from WMO’s rotating list.  WMO maintains lists of names in order to communicate about hazards and to save lives.

2022 Atlantic hurricane namesEvery year, there are on average 84 named tropical cyclones all over the world. Over the past 50 years, every single day, they have caused on average 43 deaths and US$ 78 million losses  and have also been responsible for one third of both deaths and economic losses from weather-, climate- and water-related disasters, according to WMO statistics from 1970-2019. But the death toll has fallen dramatically thanks to improvements in forecasting, warning and disaster risk reduction coordinated by WMO’s Tropical Cyclone Programme.

The Intergovernmental Panel on Climate Change's Sixth Assessment Report projects that the global proportion of tropical cyclones that reach very intense (category 4-5) levels, along with their peak winds and rainfall rates, are expected to increase with climate warming. Sea level rise and coastal development have increased the risk and impact.

In view of the growing hazards, WMO is working to ensure there is universal access to early warnings and is seeking to strengthen impact-based forecasting.

Improved services

For the forthcoming season, NOAA has enhanced a number of products and services. They include::
