Heavy rain, hail and lightning from Storm Adel swept across Greece on Friday, striking Athens and several regions with early-morning downpours.

The National Observatory reported 52 millimeters of rain in Faliro and 50 mm in Alimos and Kifissia by 9 a.m.

Hail and lightning triggered major delays across Attica, with part of Pireos Street briefly closed and water outside Moschato's rail station reaching 1 meter, forcing passengers to cross in a municipal pickup.

By midafternoon, hail hit Lesvos, clogging drains and flooding streets and shops in Mytilene. Civil protection officials urged residents to avoid travel. In Mesolongi, four soldiers were hospitalized after lightning struck the 2/39 Evzones Regiment; three were released, and one was moved to Patra for tests.

Eleven municipalities closed schools as landslides, fallen trees and power outages were reported in Epirus, Corfu and Foinikounta.
