The audio stall warning seems to work fine but during our last flight on a normal approach the Angle, Angle, Push audio warning went on while well above stall speeds. It was lightly raining at the time. I did a go around because this warning normally does not alert except at the end of landing when flaring or beginning of take off.

My copilot did the next landing attempt and the Angle, Angle, Push repeated all the way from start to finish of the landing. It was also lightly raining during that landing.

I don't know whether the rain and the stall alert are coincidental or not.

Any suggestions?
