Impact verdict

Low impact. LOW: Emergency weather alert is corroborated by multiple Greek mainstream sources (iefimerida.gr, enikos.gr, inewsgr.com, ethnos.gr) but none report insured losses, named infrastructure damage, casualty figures, or loss estimates. No insurance trade press, catastrophe bulletins, or non-Greek wire/authoritative meteorological sources have been ingested. Materiality constrained by absence of evidence rather than confirmed low severity. Below commercial threshold for multi-syndicate London Market action.
