Dave chats with Rachel McInerney from the BOM Tasmania.
She explains exceptionally heavy rain has fallen across northern Tasmania over Sunday and today. A number of sites recorded extraordinary totals which exceeded previous records by very large margins.
- 7 locations set new daily rainfall records (for any month) in the 24 hours to 9am today.

In the 24 hours to 9am today the highest totals were: Fisher River 279mm, Yolla 248mm, Lake Gwendy 241mm, Lake MacKenzie 237mm, Iris River 230mm, Lake Gairdner Dam 219mm, Sheffield 216mm, Pyengana 211mm.
49 other locations about the north of the state and the Central Plateau reported between 100 and 200mm in the 24 hours to 9am today.
Some notable 24 hour rainfalls to 9am today in population centres were St Marys 167mm, Lilydale 152mm, Westbury and Wynyard 128mm, Zeehan 119mm, Ulverstone 113mm, Burnie 112mm, Deloraine 108mm, Whitemark and Latrobe 104mm, Devonport 88mm.

The heavy rain has led to Major Flooding on the Mersey, Forth, Meander, North and South Esk, Macquarie, Ouse and Derwent Rivers. Flood warnings were first issued on Saturday, well before any rain began.
New river level records set today include:
- North Esk at Corra Linn 5m , previous record 5.1m April 1929
- Forth below Wilmot 9m, previous record 7.2m 1970
- Mersey at Liena 0m, similar to previous record 1970.
Strong northeasterly winds have impacted the east coast today. The strongest gusts recorded to 3pm were Maria Island 133km/h, Mt Wellington 111km/h, Tasman Island 107km/h, Dunalley 95km/h, Cape Bruny 89km/h, Larapuna/Eddystone Point and Flinders Island Airport 87km/h.
There are Severe Weather Warnings for heavy rain leading to flash flooding and damaging northeasterly winds about eastern Tasmania. Sodden ground will make it more likely that trees may fall. This combination of rain and wind makes for hazardous driving conditions. Heavy rain and damaging winds are expected to ease on Tuesday morning.
In addition a Severe Weather Warning for damaging surf is in place for the east coast from the northern tip of Flinders Island to Tasman Island. These conditions are likely to result in coastal erosion, and some local inundation, until Tuesday afternoon.
