Oma edges closer to Queensland coast as seas rise
THE powerful surf predicted ahead of Cyclone Oma began to arrive on the Sunshine Coast overnight with maximum wave heights measured by the Mooloolaba wave buoy increasing to four metres and waves to more than two metres on open beaches.
The swell period also shifted out to 13 seconds, a number that indicated the swell's power and which would increase through the day.
The increase in height and power came as the swell direction shifted from east to the northeast.
This morning's high tide of 2.14m at 9.26am in Mooloolaba would bring further erosion to beaches.
Cyclone Oma's slow march southwest towards the Queensland coast continued overnight at 8km/h placing it 960km from Brisbane.
It was expected to close within 400km of the Sunshine Coast on Sunday before hooking in and then tracking north along the coast.
Considerable uncertainty remained about where it may make landfall.
The Bureau of Meteorology said latest tracking showed the best estimate of the cyclone's future movement and intensity.
"There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre," BOM said in advice.
"Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this."
The BOM has warned abnormally high tides, dangerous surf and strengthening winds were expected along the southern Queensland coast ahead of Oma.
SES groups across the Sunshine Coast met last night to prepare equipment in case of heavy rain and gale-force winds across the region.
Sunshine Coast Council and Noosa Council have also begun preparing their responses ahead of the storm pushing closer to the south east coast.
A Severe Weather Warning for Abnormally High Tides and Dangerous Surf and a Hazardous Surf Warning were current.
Gale force winds were expected to develop along exposed coastal areas of southern Queensland during Friday well ahead of Oma.
