dust advisory
Definition
A formal notification issued by meteorological services, such as the National Weather Service, informing the public that visibility is expected to be reduced significantly due to blowing dust or sand, typically as a result of high winds.
A polite way of saying your commute is about to look like a scene from an apocalypse film, but with less budget and way more gritty windshield residue.
Examples
The meteorologist issued a dust advisory, which is just a fancy professional signal that my freshly washed car is about to undergo a rugged off-road makeover by the wind.
I checked the app to see if it was safe to go for a run, but the dust advisory reminded me that the East Valley air currently has the consistency of a sandbox at high velocity.
When the National Weather Service posts a dust advisory, it is not a suggestion to start a haboob-themed photography session, but rather an invitation to stop breathing the local geology.
