Hi Warren & Liz,
Cat 2 rating is not very bad but it is scary. I was in Cairns for cyclone Joy back in '90. It just stalked the area for three days.
No water , no power. At night was the worst. The house just kept shaking so much I was ready to bolt downstairs at the first cracking noise. Didn't happen and all cleared in the end.
I do not envy at all what you may be going through soon. Hopefully it will degenerate losing intensity quickly.
Take care you two.
Cheers Marty
