Areas affected...much of southern Florida

Concerning...Severe potential...Watch unlikely 

Valid 031917Z - 032145Z

Probability of Watch Issuance...20 percent

SUMMARY...Locally strong wind gusts and perhaps a brief/weak tornado
remain possible across southern Florida today, but a watch is not
anticipated at this time.

DISCUSSION...Daytime heating along with mid to upper 70s F dewpoints
is resulting in moderate instability, which is aiding a band of
convection over far southern FL. Additional cells east of the main
band are noted on radar, with signs of outflow surges pushing
northwestward.

Thus far, low-level shear has not strengthened much. Area VWPs
indicate 0-1 SRH values generally in the 75-100 m2/s2 range, which
is on the low-end for tornado potential. However, as the TC deepens
and low-level convergence increases, some of these bands could
beco*e a bit better organized, at which time the stronger cells
could exhibit transient mesocyclones. Otherwise, moderate mean winds
in the lowest few km will favor strong to locally damaging wind
gusts.
