A well-defined low-pressure system in the southwestern Gulf of Mexico was forecast to become a tropical depression or Tropical Storm Wilfred as soon as Thursday, according to the National Hurricane Center.
If the system turns into Wilfred, it would be the 21st named storm - and the last name on the list for the 2020 Atlantic hurricane season. Any other storms that form would then be named after the Greek alphabet, beginning with Alpha, Beta, Gamma and Delta.
Elsewhere in the Atlantic, Hurricane Barry strengthened into a powerful Category 4 storm as of the 5 p.m. update, as Vicky and Sally faded away.
As of 2 p.m. Thursday, the Gulf of Mexico system was forecast to meander over the southwestern Gulf of Mexico for the next few days before moving slowly north to northeast on Friday and Saturday, according to the hurricane center.

An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system Thursday afternoon. Its chances of developing into a tropical cyclone in the next two to five days were 90 percent.
Another disturbance in the far eastern Atlantic with a chance of forming into a tropical depression is also on the National Hurricane Center's radar. It had a 40 percent chance of forming into a tropical cyclone in the next 48 hours and 50 percent in the next five days.
The system, described as an elongated area of low pressure, was producing showers and thunderstorms a few hundred miles south-southwest of the Cabo Verde Islands on Thursday, according to the hurricane center's 2 p.m. advisory.
"Environmental conditions are expected to be conducive for development during the next few days, and a tropical depression could form before upper-level winds become less favorable over the weekend. The low is forecast to move west-northwestward at 10 to 15 mph during the next several days," forecasters wrote.
Forecasters are also tracking Hurricane Teddy, which strengthened into a Category 4 storm with 1240 mph winds Thursday evening, as it continues to move toward Bermuda. As of the 5 p.m. update, forecasters said that Teddy could edge closer to Category 5 on Friday, but it was expected to weaken back to a Category 2 or 3 before it approaches Bermuda on Sunday.
Tropical Storm Vicky is expected to weaken back into a tropical depression soon and Tropical Depression Sally is forecast to move through Alabama and Georgia and into South Carolina late Thursday or early Friday. Sally is expected to become a remnant low either Thursday night or Friday morning, according to the hurricane center's final advisory on the system at 5 a.m.
