US National Oceanic and Atmospheric Administration revises multi-year statistics
The United States National Oceanic and Atmospheric Administration (NOAA) has changed the average number of storms in the Atlantic hurricane season. For this, data were used for a thirty-year period: from 1981 to 2020.
Prior to that, the agency used the twenty-year period 1981-2010: then, on average, there were 12 storms and 6 hurricanes per year, including three powerful hurricanes (with a wind speed of at least 178.6 km / h).
Now the number of storms and hurricanes has increased: 14 storms, seven hurricanes, including three powerful ones.
Earlier, Colorado State University predicted that 17 storms and 8 hurricanes are expected in the 2021 hurricane season, which begins on June 1, four of which will be powerful.
