Tropical Storm Lisa (2016)

Tropical Storm Lisa was a long lived system that existed in the eastern Atlantic during mid to late September.

The origins of Lisa can be traced back to a tropical wave that emerged off the coast of Africa on September 16. Moving in a generally westward direction, the wave organised into a tropical depression at 1200 UTC on September 19 whilst in an ideal environment. However, after genesis, the depression would struggle with dry air, before intensifying into Tropical Storm Lisa the next day as conditions relaxed around the cyclone.

Continuing to move in a northwestern direction, Lisa slowly intensified, and reached a peak intensity of 50 mph on September 21 before encountering increased shear, which weakened the system to a minimal tropical storm before relaxing and allowing the cyclone to reintensify the next day, when the system briefly peaked at 50 mph again before seccumbing to increasing shear and dry air from a nearby upper level low. Lisa remained a minimal tropical storm, until its circulation became exposed on September 24, and the system weakened to a tropical depression, opening out into a trough later the same day.

For the next several days, the system was monitored for potential regeneration, until it was absorbed by a developing extratropical cyclone near the Azores on September 29. As a tropical cyclone, Lisa had no known impacts on land.
