Victorians are being told to watch for more flooding as the state gets deluged with record rains.

A flash flood warning was issued for Wangaratta, Byawatha and surrounding areas including the Hume Freeway on Thursday night and authorities are bracing for continued high water levels on Friday.

People are reminded not to drive through floodwater, after 120 people needed rescuing from the Hume Freeway south of Wangaratta, including 17 by helicopter.

All up, 400-500 vehicles were impacted by floodwaters on the Hume Freeway, according to the alert.

More than a month's worth of rain has fallen across parts of Victoria and the wild weather is expected to continue through Friday.
