A deep low pressure system is developing over the state on Thursday which is forecast to move East and be located North East of Tasmania on Friday morning. Hobart is likely to see rainfall increase with moderate to locally heavy falls during Thursday and Friday as deep strong South East winds drag high amounts of moisture across the coast.
The May daily rainfall record at Botanical Gardens in Hobart is 49.5mm set back in 1973, records began here in 1841!
Nearby at Ellerslie Road in Hobart the record is 46.7mm set back in 1958, records began at this location in 1882.
This system certainly has the potential to set new rainfall records in Hobart so we will just have to wait and see if that actually happens.
Damaging winds are expected to greatly increase late Thursday as the low moves East and deepens. These winds will come from a different direction than people are used to in Tasmania. Instead of being the typical South West to West they will be South to South East straight off the coast. Wind gusts may reach 100km hr in Hobart with higher gusts to 125km hr across elevated areas.

20cm of snow is expected across Central districts above 900m during Thursday.
Most of Eastern half of Tasmania is set to receive a drenching along with strong to damaging winds over the next 2 days. The system moves North East along the NSW coast on Saturday which will ease conditions across Tasmania.
