As Tropical Storm Dexter continues to track northeastward north of Bermuda, posing no threat to land, forecasters are keeping an eye on two systems in the Atlantic with potential for development later this week.

System could form off Florida coast

A weak surface trough currently located several hundred miles off the coast of the southeastern United States is expected to form an area of low pressure in a day or so.

The National Hurricane Center says environmental conditions appear favorable for gradual development of this system, and a tropical depression could form by the latter portion of this week or weekend as the low initially moves slowly westward, but turns more northward by this weekend.

Tropical wave has medium chance of development

A tropical wave over the far eastern tropical Atlantic has a medium potential (50% chance) of development.

The National Hurricane Center says environmental conditions are expected to be conducive for gradual development during the next few days, and a tropical depression could form late this week or over the weekend as the system moves generally west-northwestward across the central tropical or subtropical Atlantic.

Dexter remains over open Atlantic

As of Tuesday morning, Dexter was moving at 12 mph northeastward and is expected to stay over open waters, well away from the U.S. East Coast.

The storm has weakened a bit with sustained winds dropping to 40 mph. It is forecast to re-intensify as a post-tropical in the next couple of days over the North Atlantic.

Although Dexter will not approach land, its sustained winds are expected to kick up seas along parts of the northeastern U.S. and eastern Canada.
