Areas affected...Southern Florida

Concerning...Tornado Watch 24...

Valid 230518Z - 230715Z

The severe weather threat for Tornado Watch 24 continues.

SUMMARY...A broken band of strong storms continues moving slowly
southeast across southern Florida.  Isolated severe/tornado risk
continues.

DISCUSSION...Latest radar loop reveals roughly 20 kt southeastward
progression of the band of storms which now extends from Indian
River County to Collier County, while individual cells (some of
which continue to exhibit weak low-level rotation) move quickly
northeastward.  Extrapolation of current line movement suggests that
the band will clear the coast/keys by 10-11 Z.

Until the line moves offshore, risk for locally damaging winds/hail
and a tornado or two will continue, as the pre-frontal environment
(per evening raobs and the latest VWPs) remains supportive of
updraft organization/rotation.
