The majority of the Tropical Atlantic remains quiet this morning.
A strong upper low over the central Atlantic is producing shear throughout much of the Atlantic and preventing any development over the next 48 hours.
A deep trough off the East coast will also produce southwesterly upper level shear throughout the western Atlantic.
A ridge will build [...]

There is a slight uptick in activity over the Tropical Atlantic this morning. The most obvious area of disturbed weather is over the central Tropical Atlantic where a strong disturbance is organizing. This disturbance is producing a significant amount of convection around a developing low level center of circulation. Upper level winds will continue [...]

Strong westerly and southwesterly shear conditions to dominate much of the Tropical Atlantic this morning.
We’ll start in the Gulf of Mexico where an upper low over the southern Mississippi Valley is focusing a strong jet stream from southwest to northeast across much of the Gulf. As a result, dry air is building into the [...]

The tropical Atlantic remains quiet this morning. The remnants of Fred is looking more and more cold-core by the hour and is certainly not showing signs of any rapid development. As the remnants drifts to the west, a strong trough over the western Atlantic will draw the remnants to the north and then northeast [...]

The remnants of Fred continues to track to fight back, however the future of this disturbance and the one further to the east have a rather impressive road block to the west in the form of a deep trough over the western Atlantic.
Showers and thunderstorms have once again fired up on the northeastern quadrant [...]

The strong upper level troughs and upper level low pressure systems throughout the tropical Atlantic this morning continues to inhibit any significant development throughout the region. Any tropical wave exiting the African coast is running into strong southwesterly shear that will tear apart any potential system.
Meanwhile the deep trough moving through the Gulf of [...]

The remnants of Fred is still trying to hold on over the central Atlantic as showers and thunderstorms continue to flair up to the north of the weak low level center. There is a slight chance that this disturbance redevelops into a tropical depression once again, but the threat of this system impact any [...]

As expected, the strong shear over the central Atlantic has completely torn Fred apart and as a result, Fred is now a remnant low pressure system. Over the next several days, the remnant low of Fred will be absorbed into the stronger upper troughs to the northwest and will not have any significant impacts [...]

As expected, Fred continues to weaken under the influence of strong southwesterly shear. The shear is forcing much of the convection of Tropical Storm Fred to the east of the center of circulation.
Over the next 48 hours I expect Fred to continue to weaken and will no longer remain an organized tropical system by [...]

Hurricane Fred continues to slowly weaken over the eastern Atlantic as strong southwesterly upper level winds are producing significant shear over the tropical system.
The majority of the convection with Fred is focused over the northeastern quadrant of the storm this morning. Fred continues to drift northward as the steering currents have become weak due [...]
