The agency said it would soon unveil new modeling and computing capabilities that improve its forecasting abilities.
The National Oceanic and Atmospheric Administration projected a “near normal” Atlantic hurricane season Thursday, though officials cautioned unusually high sea-surface temperatures and a likelyNOAA said the season, which runs from June 1 through Nov. 30, could bring between 12 and 17 named storms. Five to nine of those could become hurricanes, with one to four hitting Category 3 or higher.
and warm waters causes “a lot of uncertainty.” He said that’s why NOAA’s predictions are roughly split, with a 40 percent chance of a near-normal season and an equal 30 percent probability of below and above normal.events typically reduce storm activity, with anywhere from six to 18 named storms in a year according to historical data. But anhas occurred only one other time with comparatively high sea surface temperatures amid an active storm era, muddying the outlook for this season.
NOAA next month will launch an improved primary hurricane model that Spinrad said would boost track and intensity forecast accuracy by 15 percent. In July, NOAA’s computing capacity will grow by 20 percent, enabling the agency “to run more complex forecast models, and provide faster and more efficient computing power for operational prediction, research and development,” he said.
NOAA earlier this month also extended its probabilistic storm surge models to Puerto Rico and the U.S. Virgin Islands, which Spinrad said would help the territories better prepare for storms.

NOAA index tracks how greenhouse gas pollution amplified global warming in 2022Greenhouse gas pollution from human activity trapped 49 percent more heat in the atmosphere during 2022 than those same gases did in 1990, according to an annual NOAA report. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of heat-trapping gases generated by human activity, including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and 15 other gases. The AGGI converts the complex scientific computations of how much...
