A severe weather warning covers northern Victoria as life-threatening flash flooding and intense rainfall threaten communities, with Mildura receiving substantial rainfall since Saturday.

As context, an emergency warning for dangerous flash flooding was issued in South Australia earlier in the week due to an intense rainfall event, and a separate BoM warning anticipated heavy rainfall in SA before spreading to Adelaide over the weekend.

Thunderstorms are expected to drive the heavy rainfall, bringing a real risk of dangerous flash flooding across the warning area.

South Victoria was largely spared, recording only 5–10 millimetres of rain, including metropolitan Melbourne.

State Emergency Service units in Victoria and NSW advise people to avoid driving through floodwater and stay away from waterways.

Mildura recorded 66 millimetres on Saturday and 83 millimetres after 9am Sunday, contributing to rapid flooding and inundation of homes.

The Bureau of Meteorology cautioned that six-hour rainfall totals could reach up to 100 millimetres, spanning about 650 kilometres from Seymour in central Victoria to Broken Hill in far western NSW.

Other parts of northern and western Victoria saw up to 80 millimetres of rain between 9am Sunday and 7am Monday, with Tutye and Kerang recording 91 and 80 millimetres respectively.

A historical note highlights that Coober Pedy in northwest SA has received minimal rainfall in recent months, underscoring variability in regional rainfall patterns.

Emergency services logged more than 110 calls for help in Mildura from midday Sunday to 7am Monday, and 160 calls across the rest of Victoria, mainly for flooding, downed trees, and property damage.

Meteorologists expect rainfall to move through central, northern, and north-eastern Victoria through Monday, with clearing conditions by tonight in many areas and humidity easing in Melbourne late Monday into Tuesday.

Lingering showers are forecast for far-eastern Victoria on Tuesday, followed by sunshine for much of the state midweek and into the long weekend.
