Cyclones are - notoriously - very fickle to predict, so be sure to keep an eye on the current severe weather warnings for your area and to regularly check the cyclone's predicted path if you happen to live in Queensland anywhere south of Rocky.
"Sandbags should also be used in front of doorways, roller doors and brickwork vents".
Wide Bay Volunteer Marine Rescue's Bill Ker said conditions are likely to be particularly risky for small and recreational watercraft.
"These conditions are then expected to extend south over the remaining southeastern Queensland coast during this evening and Friday".
Closures may continue on Sunday, depending on weather conditions.
However, it is predicted that it may still be close enough to the coast to affect sea and swell conditions.
A flood warning has been issued for catchment areas in the coastal regions along with a few interior parts between New South Wales border and Gladstone to prepare them for heavy showers in view of Cyclone Oma.
While it is unusual for a cyclone to track this far south, it is not unprecedented.
The Bureau of Meteorology says as Oma makes her turn - which will take more than 24 hours for her to complete - her effects will continue to be felt on the Gold Coast. "A crossing is not certain yet, and there are scenarios where it may linger off the coast", he said.
The longer the storm lingers, the more damage it is likely to cause as waves as high as six metres have been seen along the shore.
The weather system was already bringing hazardous surf conditions and abnormally high tides.
"A severe weather watch is now in place for Friday and Saturday for upper parts of the North Island, as warm tropical air is expected to bring rain with potentially heavy falls to Northland and north Auckland", says meteorologist Rob Kerr.
But if you're thinking about hitting the beach for a swim, you may want to think otherwise as it could be a criminal offence.
Mr Gray said it probably wasn't the best weekend to take a drive to the coast, as conditions may not be ideal.
Monday will be dry with the winds dropping off quickly in the morning as a high pressure builds.
"Sunday night die off but cyclone Oma is very unpredictable".
Forecasting images showed "the range of likely tracks of the cyclone centre" but this is "uncertainty associated with tropical cyclone forecasting", the Bureau website advises. The system will not only bring damaging rainfall over many parts of Australia but also ferocious winds along with it.
"Due to the uncertainty in the future movement, the indicated winds will nearly certainly extend to regions outside the rings on this map", it said.
