Fears of damaging winds and ‘flash flooding’ as downpour continues

The Bureau of Meteorology said that storms were “re-developing in the west”, with a severe thunderstorm warning in place for the South West and Wimmera districts.

“Severe thunderstorms are likely to produce damaging winds and heavy rainfall that may lead to flash flooding in the warning area over the next several hours,” the bureau said.

“Locations which may be affected include Horsham, Nhill and Hamilton. The warning area may move eastwards during the afternoon and evening.“

Nhill, around 260 kilometres north-west of Ballarat, recorded 18.8 millimetres in a thunderstorm at midday, with the bulk of the rain falling in 15 minutes.

A heavy rainfall warning for the Northern Country, North Central, North East and parts of Central and Mallee districts is also in place for Friday afternoon, potentially affecting Ballarat, Echuca and Wodonga.

“Heavy rainfall leading to flash flooding has already been observed in western and central parts of the warning area, and will extend eastwards during the day while contracting from the west,” the bureau said.

“Widespread totals of 30 to 60 millimetres are expected, with isolated heavier falls of 80 to 90 millimetres possible. The heaviest falls are more likely to be experienced with thunderstorms.”

The State Emergency Service said in dangerous driving conditions, people should “pull over away from trees, drains, low-lying areas and floodwater” and avoid travel altogether if possible.

“Stay safe by avoiding dangerous hazards, such as floodwater, mud, debris, damaged roads and fallen trees,” the SES said online.

“Check that loose items, such as outdoor settings, umbrellas and trampolines are safely secured. Move vehicles under cover or away from trees. Stay indoors and away from windows.”
