Tears streamed down my face.
Literal
Tears [subject-が] my face [object-を] tracing fell.
伝わる ('to be transmitted, passed along, conveyed') is a related but distinct form from 伝う ('to trace, follow along'). In this context 伝わる means the tears follow a path along the face — 伝わって落ちる ('traced and fell') captures the same imagery as the more idiomatic 伝って流れる, with slightly different lexical choice.
