Delays at airport after deluge, widespread power outages, building damage, roads flooded; Emergency warning over Castlemaine, Seymour; Heavy rain forecast for Shepparton, Wangaratta, Echuca, Euroa, Yarrawonga, Mildura, Hattah, and Robinvale

While people in the Castlemaine and Seymour areas are being urged to shelter indoors from the rain, those areas are far from the only ones likely to be drenched tonight.

Authorities say heavy rainfall that may lead to flash flooding is likely over the next several hours across northern Victoria, including in Shepparton, Wangaratta, Echuca, Euroa, Yarrawonga, Mildura, Hattah and Robinvale.

For these areas, the advice is as follows:

• Park your car undercover and away from trees.
• Stay inside if conditions outside appear dangerous.
• Contact family members and neighbours to ensure they are aware of the situation, if safe to do so.

In Victoria’s east, hailstones are predicted as well as flash flooding.

Residents of Cann River are being urged to do all of the above, and also to be aware of potential hazards caused by the severe thunderstorms, including floodwater, debris, damaged buildings and fallen trees.

Forty-one millimetres of rain fell in Kyabram, north-central Victoria, between 6pm and 7.25pm.
