All eyes have been on what was tropical storm Florence, and for good reason. Devastating flooding continues to impact North Carolina. You can read about the latest Florence update here.
While there are still two tropical storms in the Atlantic, neither will impact the United States, and they are quickly weakening Sunday morning.
Cool water and high wind shear is helping to weaken Tropical Storm Helene this morning. It's currently booking it off to the northeast at 25 miles per hour. On this current track, if it can hold together long enough, Helene will bring rain and gusty winds to Ireland and the U.K.
Joyce is barely holding onto tropical storm status and is caught up in mid-level flow causing the storm to essentially meander in the open ocean. Wind shear is also working to tear the storm apart, and more weakening is expected throughout the day.
What was tropical storm Isaac is now a disorganized area of storms, but a very brief window could allow for some tropical development. That window is the next few days as it moves west toward Jamaica into an area of weak wind shear.
The bright red that you see on the graphic above is that high wind shear that helped weaken Isaac in the first place. A small break in that shear could allow some tropical development, but another area of wind shear going into the Gulf should but a damper on major redevelopment.
Another way of looking at that is the moisture transport. Here's Isaac Sunday morning:
But then here's the forecast moisture transport. Notice how there isn't much showing up. As that wave that was Isaac hit that wind shear, it worked to tear it apart. That's why a lot of tropical redevelopment isn't expected over the next week.
