On May 25th, outdoor mold spores in Philadelphia were recorded at over 7000 spores per cubic meter.

The overall tree pollen volume also increased to 700 pollen grains per cubic meter of air, which is more than double of the volume recorded on Tuesday.

Authorities have warned that this increase in mold spores and pollen can provoke moderate to severe allergy symptoms.
