I found this yesterday on twitter - it's an accidental find as i wasn't especially looking. It is the allergy forecast for Southern Colorado with the headline "Now, weeds are at a high level! :/ "
Trees - None
Grasses - High
Weeds - Very High
Mold - Low
The background image is of dandelion seed heads, which is really unfair as they don't cause allergies. It's a common image to use, but as the seed head doesn't have any pollen you can't be allergic to it. Here is an interesting blog post explaining it :
