WEA sent 10/24/2022 @ 1:22 am
When a hazard isn't named and a protective action is recommended, message receivers are likely to delay. A phenomena that researchers call "milling" involves looking for more information before taking action. In this example, there is mention of an "incident," which implies something dangerous. In many cases, WEAs are sent without including any information about the threat while instructing people to shelter or evacuate immediately. A complete message will include a name or description of the hazard and its potential consequences. When message receivers understand why they are being asked to shelter, they are more likely to respond appropriately to the message. In this case, the WEA was issued at 1:22 am, so people in the area may have already been tucked away and asleep when the WEA woke them with advice to shelter in place.
