San Diego Evening Tribune, June 6, 1913.

The city awoke this morning in a climate apparently transplanted. Shivers ran where shivers had not run before and the weather bureau was bombarded from early morn with telephone calls to know the reason why. Lightly constructed “Southern California” houses shrank with the cold and fairly trembled with the quivering of their occupants.  –San Diego Evening Tribune, January 6, 1913.
