Tomorrow is the usual testing day of Austria's sirens and for the first time, a new cell broadcast warning system will be tested (12 to 12:45 pm).
Apparently the mobile phones will be quite loud, so if you have to drive at noon, the authorities recommend turning off your mobile phone or putting it into flight mode.
(And I think it should be easier to find information in English about this?! Why is the only result in English from a quick google search from Kronenzeitung?! I don't want to link to them...)
