HOLT, Fla., Aug. 15, 2017–Activity in the east Atlantic Ocean appears to be gathering momentum as the National Hurricane Center watches two waves moving across the tropical waters.

A third wave is expected to move off the western Africa coast Wednesday.

The first area of low pressure, identified as Invest 91, is located more than a thousand miles east of the Lesser Antilles. Invest is a weather term short for investigative area.

Invest 91 is expected to move westward at 15-to-20 mph across the tropical Atlantic Ocean, crossing into the Caribbean Sea Friday.

The NHC says that while conditions appear somewhat supportive of tropical cyclone formation during the next few days, the environment should become less favorable once the system moves into the Caribbean.

The center has lowered the chances of this system becoming a tropical cyclone during the next five days from 60 to 40 percent during the last 24 hours.

The second area of low pressure behind Invest 91, now identified as Invest 92, is a few hundred miles west-southwest of the Cabo Verde Islands.

According to the NHC, conditions could be conducive for some slow development of this system during the next few days as it moves westward to west-northwestward, also at 15-to-20 mph.

This system has a low 20 percent chance of becoming a tropical cyclone during the next five days.

Yet a third tropical wave over western Africa is forecast to emerge over the far eastern Atlantic Ocean Wednesday.

Conditions appear conducive for some development after that time while the wave moves westward to west-northwestward at about 15 mph.

This system has a low 20 percent chance of becoming a tropical cyclone during the next five days.

Meanwhile, Gert was upgraded to a hurricane during the night with sustained winds near 75 mph. The storm is located several hundred miles west of Bermuda.

According to the NHC, swells generated by Gert are expected to spread northward along the east coast of the United States from North Carolina northward to Long Island.

The NHC says Gert has the opportunity to gather some additional strength later today or Wednesday.
