Areas affected...Parts of southern LA

Concerning...Severe Thunderstorm Watch 609...611...

Valid 220049Z - 220215Z

The severe weather threat for Severe Thunderstorm Watch 609, 611
continues.

SUMMARY...A threat for locally damaging wind may continue through
dusk.

DISCUSSION...Vigorous convection is spreading south-southwestward
across southern LA this evening. Deep-layer flow/shear is weak, but
very rich moisture (with 0-1 km mean mixing ratios of 20+ g/kg and
PW well above 2 inches) and large MLCAPE of 3000-5000 J/kg (as
observed on the LCH sounding) will continue to support a threat of
at least localized wind damage, until storms weaken or move offshore
later this evening. Some severe threat will spread south of ongoing
watches, but the limited spatiotemporal extent of the remaining
threat should preclude additional watch issuance.
