Another Atlantic Tropical System Trying to Brew

Following short-lived Tropical Depression 8, another tropical system is showing signs of brewing in the far eastern Atlantic.

Odd favor a vigorous tropical wave emerging off the African coast becoming the next tropical depression or storm in the Atlantic Basin.

What makes this wave different from its predecessors that hinted at development but failed to do so is the atmosphere the wave is moving into.

The wave is tracking south of the disruptive wind shear and dry air that has kept this hurricane season relatively quiet thus far.

Without those hindrances in place, the AccuWeather.com Hurricane Center expects the wave to gradually strengthen over the next couple of days.

The next tropical storm in the Atlantic Basin will acquire the name Humberto.

How strong the system gets will depend on how long it maintains a westward heading. Eventually, it will make a sharper turn to the north and could encounter the drier air, stronger wind shear and even cooler water.

The longer the system delays that turn to the north, the more opportunity it has to strengthen. If it manages to become a hurricane before Thursday, it would prevent 2013 from setting the record for the formation of the latest first Atlantic hurricane.

That record, for storms in the satellite era, is currently held by 2002 when Gustav reached hurricane status on September 11, according to AccuWeather.com Expert Senior Meteorologist Alex Sosnowski.

The system is expected to definitely make that northward turn prior to reaching the central Atlantic, sparing the Caribbean islands from being impacted.

Farther down the road, it appears that the system should not reach the United States.

The worst impacts to land will come over the Cape Verde Islands. Potentially flooding rain threatens to spread across the islands Monday through Tuesday. Depending on when the systems takes its northward turn, the drenching could last through Wednesday.

Damaging winds and rough surf will become greater concerns if the system is a developing or strengthen tropical storm as it crosses or passes very close to the islands.

Elsewhere in the Atlantic

A close eye is also being kept on the area of disturbed weather north of Puerto Rico and Hispaniola that contains part of what was once-Tropical Storm Gabrielle.

The window can open for this area to gradually become better organized if the disruptive wind shear in its path to the north lessens.

Even if development occurs, the cold front set to bring another shot of cool air to the Northeast late next week will keep the system away from the United States.

Interests in Bermuda, however, should monitor the feature. Some drenching showers and thunderstorms could still reach the island nation at midweek regardless of whether or not a tropical depression takes shape.

The AccuWeather.com Hurricane Center will also be watching the southwestern Gulf of Mexico for another system to follow in the footsteps of once-Tropical Depression Eight and Tropical Storm Fernand.
