FLOOD WATCH FOR ALL NORTHERN, WESTERN AND SOUTHERN RIVER BASINS.
Note: This Flood Watch is a "heads up" for possible future flooding and is NOT a Flood Warning.

Issued at 10.11am on Tuesday 5 May 2015

A flood watch continues for all northern, western and southern river basins of Tasmania.

A strong cold front is crossing the state during Tuesday. Rainfall totals of up in the range of 20 to 50mm were recorded along the north and west of Tasmania in the 24 hours to 9am Tuesday, mostly since midnight. Isolated higher totals (up to 78 mm) were observed in the the Great Western Tiers.

Widespread rainfall is forecast in the north and west during Tuesday, with additional falls up to 30 mm expected in the north east, and up to 60mm along the west in the next 24 hours.

River and stream rises may occur in northern and western river basins during Tuesday, with a small chance of localised minor flooding.

Localised flooding of small creeks and low lying areas may occur in locations that receive heavy rainfall during Tuesday.

Further cold fronts will cross Tasmania on Wednesday and Thursday. Rainfall totals of 30-40mm are possible each day, this time mainly in the west and south of the state. Again, higher totals are possible about elevated areas.

As rainfall accumulates, catchments will become increasingly saturated and minor flooding is possible in some catchments.

River and stream rises are likely in the Huon river basin from Tuesday evening and into Wednesday.

Note: This Flood Watch is a "heads up" for possible future flooding and is NOT a Flood Warning. Flood warnings will be issued for specific river basins if required. The Bureau of Meteorology does not provide a flood warning service for all of the catchments covered by this flood watch.

FloodSafe advice is available at www.ses.tas.gov.au

Road closure information is available at www.police.tas.gov.au

For emergency assistance call the SES on telephone number 132 500.
