Snow, Hail, Flood, in the centre of Australia in June, when all the tourists are visiting. I'm glad I didn't make the trip this year.
If it's flooded, don't try driving through it folks. You would not drive into fire, so please don't drive into water.
Flash floods can rise in seconds. Forget the travel plans and go back to higher ground. If you travel the outback, even on the good roads, you take provisions for a fortnight (especially two weeks fresh water supply) and adapt to the weather conditions.
