Areas affected...Portions of South Florida

Concerning...Tornado Watch 690...

Valid 091419Z - 091545Z

The severe weather threat for Tornado Watch 690 continues.

SUMMARY...Potential for tornadoes will continue late this morning
into the afternoon. The threat will gradually expand northward as
heating destabilizes the boundary layer. Wind fields will also
increasingly support tornadoes with time.

DISCUSSION...Low-level rotation has been increasing in two supercell
storms south of Lake Okeechobee. One storm produced a tornado in
Collier County just before moving into Hendry County. More recently,
the storm in central Broward County produced a tornado as well.
Storms earlier this morning generally began to weaken near Lake
Okeechobee, but temperatures have been increasing with surface
heating. That being said, the tornado threat will likely begin to
extend farther north over the next few hours. Additional updrafts in
eastern Collier County have also been slowly deepening over the last
hour. This activity could intensify and similarly be capable of
producing a tornado. Potential for tornadoes, including a strong
tornado, should continue to increase as stronger low-level flow
across the peninsula expands as Milton moves eastward and its wind
field concurrently expands.
