Teaser: "The 19/12z NAEFS is indicating IVT values 19.1 sigmas above the mean;"

3" of rain in hour - will cause flooding and damage, but is not a rare event.

Serious question, overblown or not? CEnter has passed San Diego and they got .97" of rain (SD Airport measurement). Riverside 1.4". LAX 1.27", Long Beach 1.56".

This was fear mongering: "The 19/12z NAEFS is indicating IVT values 19.1 sigmas above the mean;"

Mean for this time of year?
.1" is average rainfall for the whole month of August for Los Angeles, so if they get 3" today, it is both a massive 30x the month in a day, and also nothing to panic about.
