Tropical Storm Dexter And 2 Other Areas To Watch
Tropical Storm Dexter will track away from the U.S. East Coast after late Sunday, but there are two other areas for possible development in the Atlantic Basin over the next week.
Tropical Storm Dexter
Dexter was first designated a tropical storm late Sunday night after an area of low pressure first formed along a stalled frontal boundary off the Southeast coast between North Carolina’s Outer Banks and Bermuda.
It then sprouted enough persistent thunderstorms and separated from the front to become the fourth tropical storm of the season. It’s not uncommon for tropical systems to develop this way.

The good news is that Dexter is moving away from the U.S., and expected to become ripped apart by stronger wind shear. However, we could still see high surf and possible rip currents along the East Coast for the next several days.

Two Other Areas To Watch In The Atlantic
In addition to Dexter, the National Hurricane Center is watching two other areas for development.
1. Southeast Coast: Another area of low pressure is expected to form along the old stalled front off the Southeast coast later this week. There is a low chance it could gradually organize into a tropical depression mid- to late week while moving northwest toward the coastal Carolinas.
The Southeast is already seeing wet conditions to start this week, but this disturbance could help generate more showers and thunderstorms with locally heavy rain along the Southeast coast as the week comes to a close.
2. Atlantic Tropical Wave: The third area to watch is a tropical wave that has emerged into the Atlantic from Africa. This system could form into a tropical depression or storm late this week once it reaches the central Atlantic.
It’s no threat to land for the immediate future, but we’ll continue to monitor its progress over the coming days since it’s potential longer-term path is still uncertain.
The next two tropical storm names on the list following Dexter are Erin and Fernand.

Tropical Development Potential
(The possible area(s) of tropical development according to the latest National Hurricane Center outlook are shown by polygons, color-coded by the chance of development over the next seven days. An “X” indicates the location of a current disturbance. Any active storms are shown by a tropical storm symbol and its corresponding forecast path. )
Southeast, Lesser Antilles Favored Development Areas In August
A steep increase in tropical activity has historically occurred over the next 4-6 weeks across the Atlantic basin.
Tropical development can occur anywhere from the Gulf and Southeast coasts to the Central Atlantic and even off the coast of Canada.

This is because water temperatures are near their annual peak, Saharan air has typically mixed out, wind shear is decreasing and instability across the basin is high. These are all favorable conditions for tropical formation.
August’s favored named storm formation areas.
