User:Jarda2020/2025 Atlantic hurricane season

The 2025 Atlantic hurricane season is an ongoing Atlantic hurricane season, which is part of the annual tropical cyclone season in the Northern Hemisphere. It will officially begin on June 1, 2025, and end on November 30, 2025. These dates, adopted by convention, historically describe the period in each year when most Atlantic tropical cyclones form. However, subtropical or tropical cyclogenesis is possible at any time of the year, as demonstrated by the early formation of Tropical Depression One on May 19, making 2025 the eighth consecutive year that a storm formed before the official start of the season.

Starting with this season, the National Hurricane Center (NHC) began to issue regular Tropical Weather Outlooks on May 15, two weeks earlier than it did in the past. This change was implemented in light of the fact that named systems had formed in the Atlantic Ocean prior to the official start of the season in each of the preceding six seasons.

Seasonal forecasts
In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States National Oceanic and Atmospheric Administration (NOAA)'s Climate Prediction Center, Tropical Storm Risk (TSR), the United Kingdom's Met Office, and Philip J. Klotzbach, William M. Gray and their associates at Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to NOAA and CSU, the average Atlantic hurricane season between 1991 and 2024 contained roughly 14 tropical storms, seven hurricanes, three major hurricanes, and an accumulated cyclone energy (ACE) index of 72–111 units. Broadly speaking, ACE is a measure of the power of a tropical or subtropical storm multiplied by the length of time it existed. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 mph (63 km/h). NOAA typically categorizes a season as either above-average, average, or below-average based on the cumulative ACE index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season are sometimes also considered.

Pre-season forecasts
On December 11, 2024, TSR issued an extended range forecast for the 2025 hurricane season, predicting way above-average activity with 21 named storms, 7 hurricanes, 3 major hurricanes, and an ACE index of about 140 units.

Season effects
This is a table of all of the storms that have formed in the 2025 Atlantic hurricane season. It includes their duration, names, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2025 USD.
