NOAA: 4 Tropical Cyclones May Form

National Hurricane Center Tropical Outlook September 2, 2020

MIAMI, Florida – NOAA’s National Hurricane Center in Miami, Florida issued a Tropical Weather Outlook at 2 p.m. Eastern Daylight Time on Wednesday, September 2, 2020, due to the presence of two other systems that may form into tropical cyclones within the next 5 days in addition to Tropical Storm Nana and Tropical Storm Omar.

The first system is a tropical wave located just off the coast of West Africa (marked with an orange “X”).

This wave is expected to merge with a disturbance centered a couple of hundred miles southeast of the Cabo Verde Islands toward the end of the week.

NHC forecasters say that the gradual development of this system is then possible, and this system could become a tropical depression by this weekend while it moves slowly westward over the eastern and central tropical Atlantic Ocean.

This system has a 60% chance of tropical cyclone formation within the next 5 days and a 10% chance within the next 48 hours.

The second system is a small area of low pressure that has formed about midway between the Windward Islands and West Africa (marked with a yellow “X”).

NHC forecasters say that showers and thunderstorms associated with the system have changed little in organization since yesterday evening.

Some additional development of this system is possible this week as the system meanders over the central tropical Atlantic Ocean.

This system has a 30% chance of tropical cyclone formation within the next 5 days and a 20% 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 Paulette and Rene.
