       Areas affected...North-central MS
    
       Concerning...Tornado Watch 76...
    
       Valid 250124Z - 250215Z
    
       CORRECTED FOR ERROR IN SPATIAL DELINEATION
    
       The severe weather threat for Tornado Watch 76 continues.
    
       SUMMARY...An intense tornado (EF3+) is likely ongoing with a
       supercell tracking northeastward across western Sharkley County MS,
       and this storm should persist for the next 30-60 min.
    
       DISCUSSION...Latest radar data shows an organized cyclonic supercell
       tracking northeastward across western Sharkley County MS, with a
       VROT above 70 kt and well-defined TDS up to 13k ft -- indicative of
       an intense tornado (EF3+) given the parameter space (STP of 4). The
       downstream environment features a large, clockwise-curved hodograph
       per DGX VWP (around 430 m2/s2 0-1 km SRH) amid rich boundary-layer
       moisture. This will support the maintenance of this intense
       supercell toward the northeast for the next 30-60 min.

    Take it FWIW, but the system that will cause these events crashed into California yesterday and Monday….and in my 15 years living in Los Angeles it was the strongest system I’ve experienced.  Some highlights:

    - 102 mph wind gust in Valencia, CA

    - confirmed tornado in Montebello, CA (strongest observed in the Los Angeles area since 1983).  Rating still TBD but will likely be assigned an EF-0 or EF-1 based on damage produced 

    - several 60-90 mph wind gusts in San Francisco due to a bomb cyclone that developed at the center of the low pressure system 

    I got my eyes on this one

     

    How rare is it for LA/Cali to get tornadoes? 

     

    Edit: Neverminded.  Just noticed the mention of 1983.   

     

    That's pretty rare
