NOAA: 6 Tropical Cyclones May Form In Next 5 Days

National Hurricane Center Tropical Outlook September 19, 2020

MIAMI, Florida – NOAA’s National Hurricane Center in Miami, Florida issued a Tropical Weather Outlook at 8 a.m. Eastern Daylight Time on Saturday, September 19, 2020, due to the presence of two other systems that may form into tropical cyclones within the next 5 days in addition to Hurricane Teddy, Tropical Storm Wilfred (formerly Invest 98L), Sub-Tropical Storm Alpha (formerly Invest 99L), and Tropical Storm Beta (formerly Invest 90L and Tropical Depression 22).

The first system is post-tropical cyclone Paulette that is a few hundred miles southwest of the Azores (marked with an orange “X”).

The cyclone is forecast to continue southward for the next day or so and then stall over marginally warm waters a few hundred miles south of the Azores.

NHC forecasters say that the cyclone could subsequently redevelop tropical characteristics late this weekend or early next week while it moves little.

This system has a 50% chance of tropical cyclone formation within the next 5 days and a 40% chance within the next 48 hours.

The second system is a tropical wave located near the west coast of Africa (marked with a yellow “X”).

NHC forecasters say that development of the system, if any, will be possible while it moves generally west-northwestward over the far eastern Atlantic.

This system has a 10% chance of tropical cyclone formation within the next 5 days and a near 0% chance within the next 48 hours.

If these systems become tropical storms or hurricanes, the next name on the 2020 Atlantic Hurricane Greek Alphabet Names List is Gamma.
