SRH (Storm Relative Helicity) is a measure of the potential for cyclonic updraft rotation in right-moving supercells, and is calculated for the lowest 1-km and 3-km layers above ground level. There is no clear threshold value for SRH when forecasting supercells, since the formation of supercells appears to be related more strongly to the deeper layer vertical shear. Larger values of 0-3-km SRH (greater than 250 m**2/s**2) and 0-1-km SRH (greater than 100 m**2/s**2), however, do suggest an increased threat of tornadoes with supercells. For SRH, larger values are generally better, but there are no clear "boundaries" between non-tornadic and significant tornadic supercells.
O NHC está quase a mandar um zé povinho para o sistema
Aproveitar enquanto há avisos. 34KT = vento equivalente a Tempestade Tropical (>63qph).
A mid-latitude frontal system is nearing the remnants of Leslie, and the two systems are expected to merge within the next 12 h or so, marking Leslie's full transition to a post-tropical cyclone. It is possible that Leslie will redevelop a closed circulation as a non-tropical low at that point.
