General aviation pilot reported a near miss with another aircraft that attempted to land on a taxiway during strong crosswind conditions. The reporting pilot communicated to the landing aircraft of the conflict and the landing aircraft performed a go around.

Narrative

I flew into ZZZ in VMC conditions; landed on Runway XX and taxied back on the parallel runway towards the ramp. It was shortly after noon; weather was clear; with a significant crosswind. There was not a lot of traffic so after landing tower advised me to 'taxi to the ramp and stay with me' which I read back and acknowledged. While taxiing back I noticed a Cherokee 6 on final. There was a fair amount of cross wind (approximately 20 knots crosswind component). The Cherokee called tower and asked 'Am I still cleared to land?' That prompted me to look up and visually see the airplane was clearly heading towards me on the taxiway and lined up to land on the taxiway. The tower replied to the Cherokee and said 'yes; cleared to land'. At that time; I immediately keyed the mic and told the Cherokee to go around. I stated 'Go around; go around; you are lined up on the taxiway; go around. The pilot initiated the go around and the tower then also instructed the pilot to go around at about the same time the pilot had initiated the go around. After a few moments the pilot radioed an apology and said 'Okay I see what I did now; sorry'. I would estimate the separation at about 50-75 feet when the pilot went around. If we had not all been on tower frequency; this could have ended much differently.
