The State Emergency Service is warning about possible flash flooding in Tasmania's north.
Sandbags have been delivered to residents and businesses and crews are on standby in Launceston, St Mary's and St Helens.
Flooding forced the temporary closure of the Commonwealth Bank in Mowbray but it has since reopened.
Mhairi Revie from the State Emergency Service says people need to be vigilant.
"Obviously we had a lot of rain overnight, 30 millimetres in Launceston alone and as you know only a week or so ago we had 230 millimetres in Gray," she said.
"So the catchments are really wet and that's going to possibly cause us more risk of flash flooding."
She says it has been the busiest year for flash flooding in a decade.
