...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN
FLORIDA THIS AFTERNOON INTO TONIGHT...

...SUMMARY...
A tornado threat may exist late this afternoon into tonight across
southern Florida as Tropical Storm Eta approaches.

...Southern Florida...

Tropical Storm Eta is forecast by the National Hurricane Center to
move north/northwest toward southern FL and the Florida Keys later
today and tonight. Ahead of Eta, low-level moisture will increase,
as will low-level wind fields, by mid-to-late afternoon. Cloud cover
and early shower activity as outer bands begin impacting the area
will limit destabilization across the southern FL Peninsula/Keys.
Nevertheless, enough instability should be present and overlapping
strong vertical low-level shear to support low-level rotation in
stronger cells. As such, a tornado or two could occur with any
rotating cells that develop, though this threat is likely to remain
short-lived and transient. The greatest risk is expected to develop
by late afternoon and spread northwest with time through Sunday
night and into early Monday morning.
