By any standard, we've just seen a very unusual weather event: a 'winter' storm in SoCal—in the month of September.
NWS was forecasting accumulations of 18 inches in the Southern Sierra, with higher totals possible. It may be an exaggeration to say we saw as much rain overnight here in L.A. as all of last season, but it sure felt like it.
Is this a harbinger of a big Sierra winter? It's not too late to pick up a Mt. Baldy season pass...
