Severe weather warning: upper level trough to bring heavy rain to the Wimmera with chance of flash flooding

A SEVERE weather warning has been issued for all areas of the Wimmera north and north-east of Horsham, with heavy rain forecast to develop on Monday night.

The warning was issued by the Bureau of Meteorology on Thursday afternoon.

A surface and upper level trough will move into western Victoria on Friday morning and move only slowly eastwards across the State on Friday, reaching central districts during the evening and then weakening. 

Rain and isolated thunderstorms will develop late Thursday night and early Friday morning over the Mallee, Wimmera and Southwest districts and extend into the Northern Country and North Central districts during Friday morning. 

Heavy rain which might lead to flash floding is possible, particularly with thunderstorms and slow moving areas of rain.

24-hour rainfall totals of 25 to 50 millimetres are forecast on Friday with isolated higher falls of 70 to 90mm possible, particularly about northern slopes of the divide. 

The State Emergency Service has advised that people should: 

  • Avoid walking, riding or driving through flood water; 
  • Keep clear of creeks and storm drains; 
  • Be aware that in fire affected areas, rainfall run-off into waterways may contain debris such as ash, soil, trees and rocks; 
  • Be alert that in areas recently affected by fires, heavy rainfall increases the potential for landslides and debris across roads; 

The next Severe Weather Warning update will be issued by 11:00 pm Thursday.

The latest warnings and forecasts are available on the Bureau’s website.
