Hurricane season peaked this week — and, according to the National Oceanic and Atmospheric Administration, it was the first time in more than 20 years that the height of the season passed without a named storm present in the Atlantic basin.

Meteorologists have pegged September 10 as the statistical apex of the Atlantic season, using records that extend back to 1851.

This year marks the first since 1992 that the height passed without any named storms somewhere in the Atlantic. A storm acquires a name once its wind speeds reach 39mph.

There have been only four named storms in the Atlantic so far this year, even though the basin is in the midst of a warm phase when storms are more likely to develop into more powerful systems.
