2 It is forbidden to mention rain until the prayer leader proclaims [it]. (And some say that before they start the Musaf prayer, the attendant proclaims "Who makes the wind blow, etc.", so that the congregation should remember [to say it] in their prayer, and that is how we practice (Mordechai on the beginning of the first chapter of [Tractate] Taanit)) Therefore, even if one is sick or has an extenuating circumstance [that prevents him from praying in the synagogue], one should not advance one's [Amidah] prayer [so it is before] the congregation's [Amidah] prayer since it is forbidden to mention [rain] until the prayer leader says [it]. But if one knows that the prayer leader proclaims it, even though one [oneself] did not hear it, one may mention it. And for this reason, the one came [late] to synagogue and the congregation had [already] started to pray [the Musaf Amidah], one should pray and mention [rain], even though one did not hear [the announcement] from the prayer leader.
