A total fire ban remains in place for Tasmania's northern and southern regions today while emergency crews battle several uncontrolled bushfires.

While the fire danger is not expected to be as high as yesterday's, there is still a ban on open fires or activities that could cause sparks in most areas.

Watch and act alerts are in place for a bushfire burning at Franklin and another one at Molesworth, which has destroyed around 700 hectares.

No serious damage to homes has been reported.

Fire Service spokesman Andrew McGuinness says crews are stretched.

"Considering we've got a lot of resources committed to these bushfires, the chief officer's made a decision to put a total fire ban in place," he said.

Mr McGuinness says it is unlikely the Molesworth fire will be brought under control today.

Shannon Fox from the TFS is warning people to remain vigilant.

"The winds are still out of the west north-west, which is pushing the fire to the south east , so still pushing in that general direction, so its still impacting on some of these communities," she said.

Ms Fox says although the alert levels for the fires have been scaled back, people still need to have their bushfire plans ready.

"A significant number of people have stayed in their residences to protect their homes," she said.

"People who have nominated to relocate from the area as part of their bushfire plan, or if they didn't have a plan, have also done so and we do have residents from those areas currently using fire refuges at the Derwent Entertainment Centre and at Coorinya, in New Norfolk."
