About pollen in Whittier
Weed pollen is the main story in Whittier today, sitting at a moderate level that could be noticeable for those who tend to react to it. Grass pollen is present but at a very low level, unlikely to cause much trouble, while tree pollen is quiet for now. Looking ahead, weed pollen is expected to ease slightly over the next several days but should remain at a moderate level worth keeping in mind if you're sensitive. Grass pollen should stay steady at a low level through the week. This pattern fits the season, as late summer into fall is typically when weeds such as ragweed become more active in Southern California, while trees like oak and sycamore, more prominent in spring, remain dormant this time of year.
