The weather bureau is confident the worst of the wild weather has passed over Tasmania's north.

Up to 6000 homes have been left without power, trees and power lines are down, and properties have lost roofs in the north and north west, after heavy rain and high winds pounded the region today.

The bad weather has forced TasRail to shut its entire network.

The tracks are expected to be closed until tomorrow morning.

The Tour of Tasmania cycling event stage planned for today was cancelled, after concerns over competitors' safety.

Forecaster Anna Forrest says conditions should start to ease over the next few hours.

"Particularly the eastern half of the state has still got the frontal system to come through, but the remainder of the state, the western half and across the north west, should start to see an easing in conditions, at least as far as the weather's concerned, the wind's probably going to take a little bit longer to moderate," she said.

State Emergency services' Mhairi Revie says locals in the greater Launceston area can collect sandbags from the S-E-S in Youngtown to protect their properties from flash flooding.

"It's really about grabbing half a dozen sandbags and putting them as a precaution over things like your doorways, maybe over your garage, those sort of low-lying areas in your property where you think water might run into," she said.
