Watching for development of three tropical areas

HOLT, Fla., Aug. 23, 2021—The National Hurricane Center has three areas to watch after Hurricanes Grace and Henri fade into history.

All three have a 40 percent chance of further development through the five-day forecast period.

More than 700 miles west of the Cabo Verde Islands, a broad area of low pressure is moving over the eastern tropical Atlantic

Little development is expected during the next couple of days due to marginal favorable ocean temperatures, according to the NHC.

However, some gradual development will be possible through the end of the  week while the system moves northwestward over the central Atlantic.

Behind that system is another area of disturbed weather associated with a low pressure system located over the far eastern tropical Atlantic.

Some slow development will be possible during the next several days while it moves west to northwest over the eastern Atlantic.

Finally, a third area associated with a tropical wave located over the eastern Caribbean Sea is forecast to form a broad area of low pressure by late this week.

Environmental conditions are forecast to become favorable for gradual development while the system moves west-northwest.

Peak of the season

As August continues to slip by, the calendar is moving toward Sept. 10, the traditional peak of the hurricane season.

This time last year, there were 14 systems; nine were tropical storms, three were category 1 hurricanes (Hanna, Isaias and Marco), one was a category 4 hurricane (Laura) and there was one depression that never developed into a storm (TD 10).

Last season was the most active hurricane season on record, as well as the fifth consecutive above-active season, beginning with 2016.

By comparison, there have been eight systems so far this season: five tropical storms, two category 1 hurricanes (Elsa and Henri) and one category 3 storm (Grace).

Predictions for storms this year are 13-20 named storms, 6-10 hurricanes and 3-5 major hurricanes (category 3 or higher).
