BLACKSBURG, Va. -

Winter is behind us but this region could still feel its' effects for several more weeks, with a phenomenon called "the pollen vortex."

All around Virginia and much of the country, this past winter was long, super cold, and labeled the "polar vortex."

The temperatures were so cold and wet, tree physiologists say, that trees and plants weren't able to release their pollen on time. Thus, the label pollen vortex when all that pent up pollen explodes all at once as the temperatures warm up.

Dr. John Seiler is a Virginia Tech Alumni Distinguished Professor, who said this pollen backup is bad for allergy sufferers.

"We've got a real cocktail of pollen in the air because there are trees blooming at the same time, that typically wouldn't."

Call it the perfect pollen storm. Bad news for folks with allergies like my teenage daughter, Marisa, who says she watches the pollen count.

"Sometimes on the weather, on the news, [meteorologists] show the pollen count and on the days when the pollen count is particularly high, I know I should take some allergy medicine before I go out the house."

Some pollen has the appearance of yellow dust, and if you have allergies, you know what you're in for.

Experts say the polar vortex forced trees to take on so much snow and ice, they weren't able to release their pollen until now. Around these parts, Dr. Seiler says certain trees are packing the most delayed pollen punch.

"Normally the birches would have been done and then the oaks would have come on and the hickorys would have come on and again they're compressed together."

First the polar vortex and now it's itchy eyes and sneezing cousin the "pollen vortex."

Salinas says she's tried just about every type of allergy medicine, including shots, but nothing seems to bring long-lasting relief. When the forecast calls for a high pollen count, I asked Marisa what she thinks.

"I'm thinking I better have a pack of tissues in my bag!"

The allergy season is only about halfway done.
