If you suffer from seasonal allergies, you’ve probably noticed your symptoms are more severe and longer lasting.

It’s not your imagination, allergy experts say. The combination of an especially wet and stormy summer and global warming is creating the longest, most difficult fall allergy season yet.

"We're going to have an allergy double whammy," Dr. Clifford Bassett, medical director of Allergy and Asthma Care of New York, tells WLSAM.com.

Wet weather conditions have led to record high ragweed pollen counts, and standing water remaining from Hurricane Irene has driven up the amount of mold around, resulting in an extraordinarily troublesome time for those who are sensitive to such allergens.

Both spring and fall allergy seasons have been "getting longer and longer ... partly due to global warming," says Estelle Levetin, chairwoman of the aerobiology committee for the American Academy of Allergy, Asthma and Immunology.

"As we're seeing warmer and warmer weather, the fall gets warmer and longer and the effect is that there's no frost to kill the ragweed and end the allergy season," she says.
