High tide flood risk passes southern Tas

The Bureau of Meteorology has cancelled a severe weather warning for abnormally high tides across southern parts of Tasmania.

The tide peaked at about 8.35am (AEDT) on Wednesday at Hobart's Battery Point at 1.85 metres, some 30cm above the usual high tide mark.

A combination of warm water, a full moon, air pressure and wind, there were initial concerns the tide may cause low-level flooding, but emergency services haven't reported any problems.

"We are seeing the tide slowly decrease and we will cancel the severe weather warning," Bureau forecaster Matthew Thomas told AAP.

The tidal anomaly can be forecast well in advance.

"It's based on the gravitational pull of the moon, not just the weather," Mr Thomas said.

The extent of the tide is subject to weather conditions which can be forecast up to 10 days in advance.
