Event narrative

Two waterspouts were observed near Little Duck Key. Both waterspouts were in the mature phase with spray rings visible. Both condensation funnel clouds were narrow.

Wider weather episode

A shortwave upper level trough over the Florida Peninsula combined with the lower tropospheric ridge axis to the east-southeast of the Florida Keys promoted a west-southwest flow. This synoptic environment supported the growth of a regenerative convective cloud line east of Big Pine Key through the Florida Bay waters north of Marathon.
