Atlantic system may become next Tropical Storm; potential threat for Lesser Antilles late this week

(Weather Channel) An area of disturbed weather in the far eastern Atlantic Ocean may develop into the next tropical depression or storm later this week and may eventually pose a threat to the Lesser Antilles by the weekend.

This tropical disturbance has been dubbed Invest 91L by the National Hurricane Center (NHC). The term “Invest” is used to identify features that have a chance to develop into a tropical depression or tropical storm.

For now, the NHC has given this system a medium chance of development during the next five days. Those odds could increase in the days ahead, however.

Invest 91L is producing a robust area of shower and thunderstorm activity as it moves westward to the southwest of the Cabo Verde Islands.

The environment around the broad area of low pressure is fairly moist, which could help aid in its ability to continue generating concentrated shower and thunderstorm activity if the area of storminess can consolidate.

Overall, the NHC says that environmental conditions are generally conducive to development in the days ahead as it moves west or west-northwest.

The good news is that we have plenty of time to monitor the progress of Invest 91L since it’s not expected to reach the longitude of the Lesser Antilles until Friday or Saturday.

It is far too early to determine any impacts on those islands or any other location farther down the road since there is uncertainty surrounding this system’s exact future track and strength.

This uncertainty is typical for this far out in time, particularly when a tropical cyclone has yet to develop.

The bottom line is that we are in the climatological peak of the hurricane season, so each tropical wave or area of the low pressure in the Atlantic basin must be watched closely for development.

The next named storm will be called “Harvey”.
