The wider storm

An upper-level low situated over southern CA provided strong upper-level forcing for ascent across the area. Cold 500 mb temperatures of -12 to -13 degrees Celsius and steep lapse rates led to moderate instability values with MLCAPE peaking close to 1000 J/kg. The combination of the upper-level forcing and moderate instability led to the development of strong thunderstorms across the southeastern portion of Imperial County with rainfall rates in excess of 2-3 inches per hour. This led to areas of flash flooding.

Began near Glamis (33.0387, -114.9352).
