Adelaide's 29mm during Sunday and Monday morning was the city's heaviest rain in two months. Adelaide is now having its third wettest summer on record, with 164mm in the gauge so far his season. This puts it within striking distance of 1937 (168.5mm) and the record 1925 (172.8mm).

Hopetoun had its heaviest rain in six years, receiving 36mm by 9am today. Rhyll (51mm) and Cerberus (43mm) both saw their heaviest in four years.
