Budding Atlantic tropical depression may be a concern through mid-July

A budding tropical system over the Atlantic Ocean may remain a concern through the middle of July as it takes a path near the Lesser Antilles then near the East Coast of the United States.
“The system, dubbed 94L, can become a tropical depression then a tropical storm at any time over the next several days,” according to AccuWeather Hurricane Expert Dan Kottlowski.
The next name on the list of Atlantic tropical storms for 2017 is Don.

As of Tuesday midday, the center of the system was located about 1,800 miles east-southeast of San Juan, Puerto Rico.
How quickly the system organizes will determine its exact track.
The system will take a slow and general path around a clockwise flow of air associated with a large area of high pressure over the Atlantic Ocean.
“Should the system ramp up quickly to a tropical storm, it is more likely to turn to the northwest and slide north of the Leeward Islands this weekend,” according to AccuWeather Tropical Meteorologist Brett Rossio.
“Should the system remain relatively weak and poorly organized, it may take a more westward track, perhaps very close to the Leeward Islands this weekend,” Rossio said.
The degree of impacts on the island in the northeastern Caribbean Sea will depend on the exact track and strength of the system as it passes by.
Either way a period of building seas, rough surf and squalls may spread westward through the Leeward Islands from Saturday to Sunday. Some impacts may occur in Puerto Rico on Sunday.
During the first part of next week, the system is likely to be traveling in waters near or just northeast of the Bahamas.
During the period from July 12 to 16, the system is likely to be located somewhere from Bermuda to the shores of the southern Atlantic coast of the U.S.
Interests in these areas should closely monitor the track and strength of the system, especially during the dates aforementioned. Impacts may range from a period of rough surf and frequent rip currents to heavy seas, flooding and damaging winds depending on the system’s exact track and intensity.
Into this weekend, features that may limit the strength of the system include dry air, Saharan dust and strong west to southwest winds at middle levels of the atmosphere, called wind shear.
“Should the system survive negative impacts through this weekend, it may enter a more favorable environment for rapid strengthening northeast of the Bahamas that includes very warm water,” Rossio said.
“In addition to the possible formation of a tropical depression and Tropical Storm Don, another system that moves off the coast of Africa could develop over the south-central Atlantic next week,” Kottlowski said.
Updates will follow as more information becomes available.
