The 2021 hurricane season should be “more active than normal“, according to NOAA. American forecasters predict, in the upper range, up to 20 named phenomena and 10 hurricanes, including 5 major. A season despite everything less active than in 2020, an exceptionally abundant year.

The National Oceanic and Atmospheric Administration (NOAA, US Meteorological Agency) announces a 2021 hurricane season “more active than normal“, in the North Atlantic basin.
Very active season announced
The new “climatological normal“was reassessed last April; it takes into account the phenomena recorded over the period 1991-2020. In this case, there were in the area, on average, per season, 14 named phenomena (the wind speed exceeds the 62 km / h), 7 hurricanes (winds are greater than or equal to 118 km / h), including 3 major ones (category 3, 4 or 5, with winds from 178 km / h).
By the end of 2021, US forecasters predict 13 to 20 named phenomena, 6 to 10 hurricanes, of which 3 to 5 are major.
As a reminder, the 2020 hurricane season was exceptional, with 30 named phenomena, 14 hurricanes, therefore 7 major ones.
Ana at the opening
This year, Ana started the ball rolling, even before the official opening of the hurricane season, set for June 1, in the North Atlantic basin.
Such prematurity is not uncommon. Indeed, since 2015, every year there has been a storm before that date.
Subtropical storm Ana formed on Saturday May 22, 280 kilometers northeast of Bermuda. She headed west. Its winds blew at 75 km / h, with gusts estimated at 90 km / h. Having only evolved in uninhabited areas, it has remained harmless.
What will be the first names of the hurricanes in this 2021 season?
There are six lists of names that rotate and repeat. When a first name corresponds to a phenomenon that generated a disaster, it is removed from the list and replaced. This is managed by the World Meteorological Organization (WMO).
Here is the effective list this year:
