'A trough currently lies over Tasmania, with a cold front expected just west of the state tonight as a deep low moves to the southwest. These features, combined with a slow moving high over the Tasman Sea, are bringing very strong northwesterly winds aloft over Tasmania, which are mixing to the surface in waves. The low will continue deepening as it passes just south of Tasmania early Wednesday, easing the winds about the north while further increasing them about the south. DAMAGING WINDS, averaging 50 to 60 km/h with peak gusts in excess of 100 km/h are possible about Bass Strait, the far northeast, the central north coast and the south. Winds are expected to ease from around midday Wednesday as the low moves away to the southeast.
The full moon on Wednesday is bringing one of the highest astronomical tides of the year to Tasmania, with high tide expected around 8:30 am for the Hobart area. This high tide coincides with warmer than average water producing a positive sea level anomaly, and the passage of a deep low just south of Tasmania. These conditions are expected to enhance an already very high tide by around 35 centimetres. '
