Remnant moisture from decaying East Pacific Tropical Storm #Juliette, which previously looked like it would just miss CA to southeast, will now likely bring some showers to far SoCal (likely San Diego County only!) over the next 48 hours! #CAwx #CAfire [1/4]

Model ensembles have shifted slightly northward w/track of Juliette remnant moisture. Most of SoCal will feel "warm and muggy" (with increased clouds/moisture) *but stay dry*, w/rain likely be confined to San Diego County (but here, soaking rain is possible!). #CAwx #CAfire [2/4]

However, models also haven't done great job so far w/exact path of this system, and have historically underestimated elevated showers/thunder on northern flank of decaying TCs near CA coast. That could bring a *low* chance of sprinkles/dry t-storms elsewhere in SoCal. #CAwx [3/4]

Note: This will *not* be like the remarkable, record-breaking, locally damaging, and fire season-ending August rainfall from Tropical Storm Hilary in 2023! This is a much weaker, more distant, and faster-decaying system; impacts will likely be pretty modest overall. #CAwx [4/4]
