The tie rod doesn't look like it broke. It looks more like the weld on the saddle broke.

That, I believe, is what happened.  Winds of 30 MPH (= 48km/h for those who use that antiquated Systeme Internacional unit system...  :-p  ) on Monday night and early Tuesday morning apparently caused an imbalance in the tie rod repair, and snapped one rod.

I hope I am reading this right, but it looks to me like the tie rods are ending well above the pin.  This to me is asking for trouble. Any slight eccentricity or lateral load will tend to de-stabilize the saddle.
