Text alerts = useless
In the run up to Cyclone Yasi we received a government text alert advising that we should evacuate. That may sound pretty useful but it wasn't. It didn't even hint as to where we should evacuate to.
A quick word about our geography. You can't evacuate to the east. That's the Pacific ocean and it's also where the cyclones come from. You can't evacuate to the west either. There isn't really a road to anywhere and if there was was you'd just be trying to outrun the cyclone. There are roads to the north and south but the cyclone was so big that trying to leave the area was pretty pointless.
I do agree about the radio. The ABC do a superb job on updates and you know the info is as sound and current as possible. Radios, as mentioned in the article, work anywhere and you don't need mains power to use them. Yasi damaged all the power, phones, Net, water, rail and road infrastructure around here but the radio towers survived and kept on working.
Old tech is sometimes the best option.
