It's rare for the models to predict a track into So CAl ,as these things( 99-100) head west with the Trades. This one is heading north.
I've been a weather radar junky for a long time and I can say that what is setting up is a very rare occurrence for this region.
I remember this storm, as I was able to see some of the damage it did in the backcountry. Got to walk the rail from Jacumba down to Dos CAbezas..
I hadn't realized that damage has been repaired to the rail line. This vid takes in the whole climb from Plaster City , through the CArrizo Gorge,up to Jacumba.
