About pollen in Mount Pleasant
Weed pollen is the main driver of today's moderate overall conditions in Mount Pleasant, with ragweed and similar late-season weeds likely to cause some noticeable symptoms for those who are sensitive. Grass pollen is contributing at a low level, while tree pollen is essentially a non-issue right now. For most people, today should be manageable, though those prone to weed allergies may want to take a bit more care outdoors. Looking ahead, weed pollen should ease slightly over the next few days but is expected to remain the most active category, consistent with the typical fall pattern when ragweed lingers into early autumn. Grass pollen is likely to taper further as the season winds down, and tree pollen should stay minimal, since local species like oak, pine, and maple are dormant this time of year and won't become active again until spring.
