rainstorm, thunderstorm a heavy rain, either in length of occurrence or in force, as in the case of a thunderstorm (thus differing from ὑετός[b], βροχή and βρέχω[a] in 14.10) In some languages a rainstorm is simply ‘a rain with wind,’ but it may also be expressed as ‘rain that hurts’ or ‘rain that floods.’

Moulton & Milligan — Vocabulary of the Greek NT
ὄμβρος. This word, which in Lk 12° is used of a ‘‘rain-storm,” appears frequently in our sources as a kind of ¢erm. techn. in connexion with land which has become waterlogged, e.g. P Tebt I. 61(4)!* (B.c. 118-7) (€4Bpoxos) διὰ τὸ[ν ὄμβρον τῶν παρακειμένων ὑδάτων. See also Sy// 804 (=*%1170)? (ii/A.D.). For the adj. ὄμβριμος cf. P Lond 12124 (iii/a.p.) (=I. p. 91) ὕδωρ ὄμβριμον. Cognate with Lat. zder, ὄμβρος retains the nasal which ἀφρός has lost (Boisacq, p. 106).
