HOLT, Fla., Aug. 19, 2017–Tropical Storm Harvey was downgraded to a tropical depression by the National Hurricane Center at 4 p.m. CDT.
The other two Atlantic systems are fighting environmental conditions to develop further.
Located over the Central Caribbean Sea, Harvey is moving west at 22 mph with winds at 36 mph.
According to the NHC, some slow strengthening is possible during the next couple of days. Harvey could regain tropical storm status Sunday or Sunday night.
Meanwhile, the low-pressure system located north of the Leeward Islands is not expected to develop further during the next couple of days while it moves west-northwest at 15-to-20 mph.
The NHC says conditions could become slightly better for development once the system is near the northern Bahamas or Florida, sometime around the middle of next week.
Right now it has a 20 percent chance of becoming a tropical depression during the next five days.
The second tropical wave located about 1,000 miles east of the Lesser Antilles is not expected to form due to dry air and wind shear.
The NHC gives this system a 10 percent chance of developing further during the next five days.
