Melbourne's wild weather on Wednesday has played havoc with St Kilda's preparations for Friday night's clash against the Western Bulldogs at Telstra Dome in a game that pits together two of the only four unbeaten teams in the competition so far this year.

The Saints were forced to bring their training session at Moorabbin forward by three hours on Wednesday afternoon due to forecasts of hail and thunder later in the day but then still could not escape the howling gales which caused havoc across Melbourne.

As the Saints players warmed up on the oval, one of the goalposts toppled over as a result of the wind while the net behind the same goals was also buckling under the strain of winds that reached over 100kph.

Earlier St Kilda coach Ross Lyon told the media a sheet of corrugated iron also blew across the ground in what was hardly the ideal preparation for a game that will be played under pristine conditions under the closed roof at Docklands on Friday night.

"I am a little bit worried, a corrugated iron sheet came off before so there is a little bit of risk but we haven’t got an alternative so there is not much we can do about it," Lyon said before training.

Lyon said the Saints had attempted to switch training indoors to the Melbourne Sports and Aquatic Centre but had been beaten to the punch by a couple of other Victorian clubs.

But Lyon said there was at least one benefit from having to train in such conditions.

"It's a good challenge to work on your technique and good technique tends to show up in difficult conditions."

"We can wear errors as long as the enthusiasm is there and you support each other but it (training in such difficult conditions) is a good challenge for the group to try to keep them focused."
