Trees are leafing out weeks early, and plants are blooming, creating allergy issues for many across the country. "We're seeing activity way ahead of schedule across the southern states.
And now we're starting to get reports for very early activity all up the eastern side of the U.S. too," Theresa Crimmins, director of the USA National Phenology Network (USA NPN), told FOX Weather. "All the way up into even New York, Massachusetts and Maine."Day length, sunlight and instinct give the birds their seasonal cue.Unseasonably warm temperatures have led to more than 1,600 daily record highs so far this year.
Over 15 cities could break record highs on Wednesday, and over 25 could set new warm record lows. That warmth leads to earlier blooming, which can supercharge allergy season.THE GREAT DIVIDE: WESTERN US TO SEE BELOW-AVERAGE TEMPERATURES WHILE WARM AIR DOMINATES IN THE EAST"When we have these warmer temperatures, a lot of plants that create pollen that are problematic for us, can flower earlier than average, and that can result in a longer and more intense pollen season," Crimmins said. "And we are hearing plenty of reports in the southern states of pollen starting to really peak and be problematic for folks already." WHY SEASONAL ALLERGIES ARE BECOMING WORSEReports of tree pollen.
