Rain during the blossom of early-flowering grasses!

It will rain in Vorarlberg on Friday and Saturday. The rainfall will wash the pollen out of the air, providing relief for allergy sufferers. It will be sunny again from Sunday. As soon as the inflorescences have dried out, pollen concentrations will rise again and cause problems.

Grasses are now the main source of allergens in Vorarlberg. Currently, smooth oatgrass, mouse-ear grass, tufted hairgrass, rough hairgrass, tufted foxtail and foxtail grass are flowering in the lowlands. In higher elevations, the first grasses have also begun to flower, though pollen levels here are still lower than in the valleys. From Sunday, people with grass pollen allergies should expect moderate levels of pollen, rising to high levels in the immediate vicinity of meadows. The sorrel and plantain species, which are also in bloom, may further increase pollen levels. Nettles have also begun to flower in Vorarlberg.

The peak of oak and beech flowering is over, and the rain ensures that only low pollen concentrations are reached. 

The first green alders have begun to flower and are causing localised pollen levels in their subalpine range as soon as the sun comes out.

In addition to the pollen types mentioned, umbellifers, elder, mulberry, black locust, horse chestnut, sour grasses, papilionaceous plants, walnut and cypresses are currently also present in the pollen spectrum. However, they pose only a very low allergenic risk.
