Earlier quoted context omitted.
Naming large weather events makes a lot of sense. Hurricanes are very good example of that. They are actual entities which behavior gets tracked. It is much easier for the public to keep up to date, when there is an easy to remember name.
But does it matter to the public whether they roads are closed due to Irene or Jacques? Admittedly, the names are catchier but I'm not certain they're necessary to convey information. It's not as if they have to keep track of a dozen hurricanes at a time.
Giving a hurricane a name raises awareness. When a named hurricane is coming, people have a very clear sign, that they should spend attention. Having the name, also makes following the events easier. So it would be quite logical to name other similar dangers.
