The State Emergency Service is reassuring Launceston residents that their properties are unlikely to be flooded by heavy rain over the weekend.
They have doorknocked homes and businesses in Newstead to advise them of the flood risk on the North Esk floodplain.
Up to 80 millimetres of rain is forecast to fall during the next two days.
About a dozen businesses and homes were inundated after northern Tasmania was drenched earlier this week.
The SES' Mhairi Revie says there will probably be some minor flooding at the weekend.
"We're probably expecting between 25 to 40 mill, potentially each day, and obviously at the moment the catchments are very wet, the rivers are high and the water hasn't got many places to go," she said.
"We're also wanting to focus on the Kings Meadows shopping strip, obviously they had some flooding occur there the other night, and we want to make sure they're very prepared in case the Kings Meadows rivulet comes up again."
