It's also the latest-forming cyclone in this part of the Atlantic given that 1966, according to Phil Klotzbach, a research study researcher in the Department of Atmospheric Science at Colorado State University.
Hurricane experts formerly cautioned typhoons could form in uncommon locations later in the season this year because of the incredibly warm Atlantic Ocean.
A storm surge of 1 to 3 feet is possible for parts of the Leeward Islands.
Heavy rainfall will be one of the storm's most major hazards and might result in flash flooding and mudslides.
