MIAMI, Florida – NOAA’s National Hurricane Center issued a Tropical Weather Outlook at 8:00 p.m. Eastern Daylight Time on Sunday, August 16, 2020, due to the presence of two systems that that may form into tropical cyclones behind Tropical Storm Josephine.
The first system is a fast-moving tropical wave located about 500 miles east of the Windward Islands that is producing increasing shower and thunderstorm activity (marked with an orange “X”).
NHC forecasters say that this system is expected to move westward at about 20 mph during the next few days, and that fast speed is likely to limit development while the system approaches the Windward and southern Leeward Islands today and Monday and moves across the eastern Caribbean Sea on Tuesday.
After that time, the system is expected to move more slowly westward across the central and western Caribbean Sea, and upper-level winds could be conducive for development during the middle to latter part of this week.
This system has a 50% chance of tropical cyclone formation within the next 5 days and a 20% chance within the next 48 hours.
The second system is another tropical wave located over the far eastern tropical Atlantic well to the southeast of the Cabo Verde Islands that is producing a large area of cloudiness and showers (also marked with an orange “X”).
NHC forecasters say that this wave will move westward at 15 to 20 mph during the next few days, and some development will be possible by the middle to latter part of the week as environmental conditions become more conducive while the system is over the central tropical Atlantic.
The second system has a 50% chance of tropical cyclone formation within the next 5 days and a 0% chance within the next 48 hours.
If these systems become tropical storms or hurricanes, the next names on the 2020 Atlantic Hurricane Names List are Laura and Marco.
NOAA and Colorado State University forecast an “extremely active” 2020 Atlantic Hurricane Season which runs from June 1 through November 30.
