Officers will be stationed at Mt Hotham and Falls Creek from Thursday ahead of the official ski season opening this weekend.

Bright Senior Sergeant Doug Incoll said the road between Mt Hotham and Harrietville could be forced to close if extreme weather hits the region.

The Bureau of Meteorology has issued flood warnings and winds up to 90km/h are forecast for Mt Hotham.

"The Great Alpine Road could be shut depending on the conditions," he said.

"People should check the status of the road before heading up to avoid delays."

While Melbourne residents are at this point banned from attending the snow, the ski fields are still open to regional residents.
