The federal government of the United States expects another active Atlantic hurricane season in 2021, with six to ten hurricanes meteorologists said on Thursday. Moreover, the season starts on 1st June and runs through 30th November. An average season usually spawns around seven hurricanes, and the season peaks in two months, such as August and September.
If predictions become true, 2021 will be a record 6th successive year of above-normal activity. In general, the National Oceanic & Atmosphere Administration (NOAA) said thirteen to twenty named storms would develop. Moreover, the specified number includes tropical storms having wind speeds of thirty-nine meters per hour or higher. Whereas according to the definition, storms become hurricanes when winds reach seventy-four meters per hour.

Of the projected hurricanes, three to five could be major, packing wind speeds of one hundred and eleven or higher. Furthermore, lead seasonal hurricane predictor at NOAA’s Climate Prediction Center, Matthew Rosencrans, said that forecasted warmer-than-average sea-level temperatures in the tropical Caribbean Sea and the Atlantic Ocean, weaker tropical Atlantic trade winds along with a boosted West African monsoon will likely be some factors in the overall activity of 2021.
The El Niño Southern Oscillation conditions are in the neutral phase, and La Niña could return later in the hurricane season. Rosencrans said that La Niña and ENSO-neutral support the circumstances associated with the continuous high-activity era. Furthermore, El Niño, the usual warming of ocean water in the tropical Pacific Ocean, tends to overturn Atlantic hurricane activity.
13 to 19 Named Tropical Storms
In 2020, the National Oceanic and Atmosphere Administration forecasted thirteen to nineteen tropical storms would spin up, of which six to ten would be hurricanes. Ultimately, a record thirty named storms formed, including fourteen hurricanes, of which seven were major hurricanes. Furthermore, the prediction of NOAA follows many this spring that also called for an additional active hurricane season.

Here are the numbers …
Forecasters predict a 70% likelihood of 13-20 named storms of which 6-10 could become hurricanes — including 3-5 major hurricanes

In April, weathercasters at Colorado State university forecasted seventeen tropical storms would form, and eighteen of which will become hurricanes. In the 1980s, William Gray, the meteorologist at Colorado State University, was the first scientist to make seasonal hurricane forecasts. AccuWeather and the Weather Channel also forecasted a harder than typical hurricane season.
Meteorologists released their forecast for the eastern Pacific basin, with where the expectation of twelve to eighteen named storms. In the same way, an average eastern hurricane season produces fifteen named storms. Eastern Pacific hurricanes and storms mainly stay out to sea and rarely affect the United States mainland, though some storms hit the Mexican west coast. In addition, remnant moisture from the storms can dump huge rain on the United States Southwest, leading to flooding.
