East to northeast at 10 to 15 knots.
Slight to moderate with a wave height of 2 to 4 feet.
An above average activity expected for the 2021 hurricane season
Colorado State University (CSU) has decreased the total number of storms expected for the 2021 Atlantic Hurricane Season. They are still predicting an above normal hurricane season given the sea surface temperatures and weaker than normal vertical wind shear.
The following is the adjusted prediction from CSU.

The 2021 Atlantic hurricane season officially ran from June 1 to November 30. A total of 21 tropical depressions formed, all of which reached at least tropical or subtropical intensity.
Consequently, the 2021 Atlantic hurricane season was the third on record to exhaust its naming list. Nine of the systems lasted for two days or less, tied with 2007 for the most since the NHC began monitoring subtropical systems in 1968.
Although the season was highly active in terms of the number of named storms, seven of those tropical or subtropical systems intensified into a hurricane and four of those became a major hurricane, which is near-average and just slightly above-average, respectively. Nonetheless, 2021 marked the record sixth consecutive above-average season in the Atlantic.
Other factors included the presence of a La Niña and abnormally heavy West African Monsoon precipitation.
