THE St Patricks and North Esk rivers were yesterday under flood alert.
The weather bureau said the St Patricks River was 1.15metres and rising at Nunamara at 7am, with the North Esk steady at Ballroom and 2.34metres and rising at Corra Linn at the same time.
The bureau advised that the North Esk was expected to peak near the minor flood level of 2.7 metres, at Corra Linn, late yesterday.
Rainfall totals of 10 to 25 millimetres were recorded in the 24 hours to 9am yesterday in the North Esk catchment, which, added to wet catchment conditions caused renewed stream and river level rises in the catchment.
At Nunamara the St Patricks River was expected to rise to near the minor flood level of 1.5 metres by late yesterday.
Strong and dangerous flows will be a hazard where river and stream levels are high over the next few days, the bureau warned.
Duty forecaster Michael Laczko said Launceston could expect a fine, partly cloudy morning today with some frost, before late morning showers, increasing to rain during the afternoon.
Rain would become heavier as the afternoon progressed.
