NOAA: 6 Tropical Cyclones May Form

National Hurricane Center Tropical Outlook September 12, 2020

MIAMI, Florida – NOAA’s National Hurricane Center in Miami, Florida issued a Tropical Weather Outlook at 8 p.m. Eastern Daylight Time on Saturday, September 12, 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 Paulette, Tropical Depression Rene, Tropical Storm Sally, and Tropical Depression 20.

The first system, named Invest 97L, is a broad area of low pressure associated with a tropical wave near and west of the Cabo Verde Islands (marked with an orange “X”).

NHC forecasters say that environmental conditions support some development during the next few days, and a tropical depression could form over the far eastern tropical Atlantic early next week while the system moves slowly westward.

By mid-week, upper-level winds could become less conducive for development.

This system has a 60% chance of tropical cyclone formation within the next 5 days and a 50% chance within the next 48 hours.

The second system is a surface trough over the north-central Gulf of Mexico that is producing disorganized showers and a few thunderstorms (marked with a yellow “X”).

NHC forecasters say that while some slow development of this system is possible, strong upper-level winds related to Tropical Storm Sally will probably limit the chances of tropical cyclone formation.

The disturbance is forecast to move westward and then southwestward over the northern and western Gulf of Mexico through the next few
days.

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 Teddy and Vicky.
