One of primary factors behind recent quiet period has been a northward-shifted monsoon trough. This has resulted in easterly waves emerging from Africa too far north to encounter conducive #hurricane conditions. These higher latitude waves have also brought dry air.

For the first time since 1941, the Atlantic has had no named storm (e.g., tropical storm or #hurricane) activity from July 3rd-August 30th. Since 1950, two Augusts have had no Atlantic named storm formations: 1961 and 1997. It remains to be seen if 2022 will join this list. 1961 ended up a hyperactive #hurricane season with an extremely busy September-November, while 1997 was a below-average season.
