  We study public announcement operators in the context of standard G\"odel
modal logic as introduced by Caicedo and Rodriguez. Over that base logic,
admitting a natural semantics over [0,1]-valued generalizations of modal Kripke
models, we exhibit three possible semantic interpretations of the public
announcement operator, all equivalent in a classical setting, and show that
these logics are all different in terms of expressive strength. We provide
partial completeness results for these logics via Hilbert-style calculi.
