Another hot Vic day, but cool change ahead

Victoria is entering its third day of hot weather but a cool change is expected to give residents some much-needed relief.

The Bureau of Meteorology has forecast a maximum of 34C on Sunday, following on from "oppressive" overnight temperatures that hovered around a minimum of 28C.

A cool change is expected to reach Melbourne about midday, but in the meantime health authorities are advising residents to stay cool and hydrated, and to look out for elderly and vulnerable people.

Temperatures in Melbourne reached a maximum of 37C on Saturday, with the hot conditions resulting in Ambulance Victoria responding to more than a dozen heat exposure incidents.
