NOAA: 4 Tropical Cyclones May Form This Week

NOAA National Hurricane Center Atlantic Tropical Weather Outlook October 4, 2020

MIAMI, Florida – NOAA’s National Hurricane Center in Miami, Florida issued a Tropical Weather Outlook at 2 a.m. Eastern Daylight Time on Sunday, October 4, 2020, that indicates two other systems may form into tropical cyclones within the next 5 days in addition to Tropical Storm Gamma and Invest 92L (red “X”).

The first system is a tropical wave located about midway between the coast of Africa and the Lesser Antilles (marked with a yellow “X” closest to South America).

NHC forecasters say that some slow development of this system is possible during the next couple of days while it moves west-northwestward or northwestward at 10 to 15 mph.

Any significant development is not expected beyond that time due to the system moving into a region of strong upper-level winds.

This system has a 20% chance of tropical cyclone formation within the next 5 days and a 20% chance within the next 48 hours.

The second system is an area of disorganized showers and thunderstorms over the central Atlantic more than 1000 miles east-southeast of Bermuda is associated with a surface trough of low pressure (marked with a yellow “X” closest to Bermuda).

NHC forecasters say that some development is possible during the next couple of days before it encounters strong upper-level winds.

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

If either of these systems become a tropical storm or hurricane, the next name on the 2020 Atlantic Hurricane Greek Alphabet Names List is Delta.
