MIAMI – A new area to watch for tropical development has emerged in the Atlantic Ocean as forecasters continue to monitor Invest 97L, which is expected to become a tropical depression or Tropical Storm Erin soon.

"Shower and thunderstorm activity has persisted and continues to sow signs of organization with a well-defined area of low pressure located just to the west of the Cabo Verde Islands," the NHC said in its Monday morning update. "If these structural trends continue, the system is likely to become a tropical depression or tropical storm, possibly as soon as later this morning."
An "invest" is a naming convention used by the National Hurricane Center to identify areas they are investigating for possible development into a tropical depression or tropical storm within the next seven days.
The designation allows the agency to run specialized computer forecast models to track the area's potential storm development.
The NHC said that locally heavy rainfall and gusty winds are expected to continue across portions of the Cabo Verde Islands, and interest there should monitor the progress of the system.
The NHC is giving Invest 97L a high chance of developing over the next two days.

Invest 96L is also churning over the central Atlantic, but development chances with that system are low.
"A weak trough of low pressure located over the central Atlantic is only producing limited shower and thunderstorm activity," the NHC said. "Significant development of this system is becoming unlikely over the next few days as the system drifts generally northward."

"While current shower and thunderstorm activity with the system is limited, this system is drifting over the warm waters of the Gulf Stream where some tropical or subtropical development could occur over the next day or two."
