Waterspout · Gulf of Mexico

The Naval Air Station Key West observer at Boca Chica Field observed a waterspout northwest of Key West. The condensation cloud extended about one-third of the way frm cloud base to the horizon. A second waterspout was observed to the southwest of the first waterspout, with the condensation cloud extending about one-fifth of the way from the cloud base to the horizon. The movement of the waterspouts was toward the northeast around 10 knots. The duration of the first waterspout was approximately 6 minutes, with the second dissipating after 15 minutes.

An inverted trough of low pressure over the Bahamas induced a northeast lower tropospheric flow over the Florida Keys. Combined with ample moisture, convective cloud lines developed repeatedly over the Lower Florida Keys. A few waterspouts were noted throughout the midday and evening hours.
