Brisbane floods this time

Well the flood situation in Brisbane has broken the river banks in my Mum's suburb, flooded the local shopping centre (just as well she raided the supermarket, along with everybody else, yesterday after being sent home from work), and is halfway up the street that runs into her street, but at this stage they don't think it will reach her house (thankfully her house is on something of a rise on the higher side of the street). This scenario is fairly much as expected, even though her suburb isn't yet listed as one likely to flood - which is a bit ridiculous really when it is now totally cut off and the only supermarket is under water. (The Brisbane City Council website is down but you can still see the individual suburb flood maps here, though it would seem the water has exceeded predictions already in some places.) So, she is now stuck at home, because all roads out are flooded, but provided her house doesn't go under should be able to wait it out.
