...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS SOUTH
FLORIDA...

...SUMMARY...
A tornado threat may develop from late this afternoon through
tonight across south Florida and the Keys, as Tropical Storm Eta
approaches.

...South FL...
TS Eta is moving slowly northwestward toward the FL Straits. 
Radar/satellite imagery show an area of heavier precipitation on the
north side of the center.  This area is forecast by most CAM
solutions to approach the coast of southeast FL and the upper Keys
after dark.  Current observations and forecast solutions suggest
that this activity will not be particularly organized, with
relatively weak UH tracks/convective elements noted.  Nevertheless,
low-level shear will maximize during this period, which appears to
be of greatest concern for a tornado or two this forecast period. 
The main time of concern will be roughly from 00-06z.  Based on
current guidance, will maintain MRGL risk, but will continue to
monitor observational/model trends.
