Rough weather across Tasmania

Wild weather has ravaged parts of Tasmania with road closures and power outages forcing some schools to close.

Wind speeds reached in excess of 100km/h at Burnie and Devonport in the northwest overnight, knocking out power to some 15,000 properties and on Tuesday at least four schools were closed at the two centres and at Ulverstone.

"Police advise all motorists in the north and northwest of the state that due to storms we have numerous reports of power lines and trees down across roads," police said in a statement.
