Gert has become the seventh named storm of the 2017 Atlantic hurricane season and, at category two, it is the strongest one of the year so far.
According to the National Hurricane Center, those three disturbances might develop into tropical depressions in the next five days.
The third wave is near the Cabo Verde Islands off Africa's west coast.
"Some strengthening later today or tonight is possible, but Gert is likely to begin weakening on Thursday and should become an extratropical low by Thursday night".
As the tropical wave passed near Antigua and Barbuda heavy rainfall should be expected.
Although Storm Gert is not expected to make landfall in the U.S., the NHC is warning of "life-threatening surf and rip currents" along coastal areas.
The National Hurricane Center said Tuesday morning that there is no current threat of landfall by Hurricane Gert.
"Those African waves are the disturbances from which tropical storms and hurricanes form in August, September and October", Bell said.
The Pinpoint Weather team continues to monitor Hurricane Gert off the east coast of the US.
The first of the three, located more than 1,000 miles east of the Lesser Antilles, is producing disorganized showers and thunderstorms.
Gert passed not too far from the East Coast of the US, and the hurricane center said big waves from the storm would continue to affect beaches in the northeastern USA through tonight. The storm is expected to stay well offshore, however ocean swells will increase next 24 hours.
2017 is quickly becoming a very active season in the Atlantic Basin. "That's really the only impact we would see".
Gert is now "way out at sea", sitting approximately 450 miles west of Bermuda and approximately 300 miles from Cape Hatteras, moving north at 12 miles per hour.
