Foreign dust-up: Canadian smoke, Saharan dust will cover U.S. together
Foreign dust-up: Canadian smoke, Saharan dust will cover U.S. together In a rare atmospheric convergence, the East Coast will experience both drifting smoke from Canadian wildfires and a sweeping plume of Saharan dust during the next few days. While residents in the Midwest recently endured the worst of the wildfire smoke—bringing air quality to near-dangerous levels—conditions are now improving. According to AccuWeather, air quality in Minnesota, Wisconsin, and Iowa is expected to clear following the recent haze. An easterly wind pattern has carried the smoke eastward, reaching as far south as Florida. But, the smoke remains generally high in the atmosphere, likely resulting only in vivid red sunrises and sunsets rather than ground-level health concerns. Adding to the spectacle, a plume of Saharan dust is making its way from South Florida toward the Gulf Coast. This dust will further enhance the brilliance of sunrises and sunsets across the region throughout the week. The paths of the Canadian wildfire smoke and Saharan dust Unable to view our graphics?

AccuWeather hurricane expert Alex DaSilva, in a report released by the forecasting company on June 2, said that the plume is roughly 2,000 miles wide from west to east and 750 miles long from north to south. The plume appears to be the largest to reach America so far this year. Alan Reppert, AccuWeather senior meteorologist, told USA TODAY June 2 that the plume will likely make it over Florida on June 4 and move over the Gulf Coast the following two days.

The fires have forced thousands to evacuate.

Pollen is expected to be bad in most states this spring – here is when the season will hit your neighborhood
As the U.S. inches closer toward the start of spring and this year's allergy season, forecasters are warning Wednesday that pollen counts are expected to be higher than the historical average across 39 states. That could spell trouble for the 25.7 percent of adults and 18.9 percent of children who suffer from a seasonal allergy. High pollen counts can lead to runny noses, itchy eyes, and uncomfortable sinus pressure. "Millions of people living with seasonal allergies will be struggling with more intense symptoms that will likely stick around longer this year in many areas,' AccuWeather Senior Meteorologist and Allergy Expert Alan Reppert explained in a statement. 'You can blame wet and warm weather patterns expected later this year for pollen levels that will reach levels higher than the historical average in many places.' Some regions will feel it earlier than others There are three main types of pollen allergy to worry about, including tree, grass, and weed. Impacts will be different across multiple areas of the country. For example, the Northeast and Great lakes regions will see a late frost and start to the growing season – coupled with lower tree pollen levels. Cooler air in the Southeast will also slow tree pollen production, and some parts of the South and Gulf Coast have already seen their pollen peaks. 'Tree pollen levels are expected to hover around average levels in the Northeast, but there could be a one-week period when higher temperatures and a lack of rainfall may send tree pollen spiking at high levels,' Reppert said. However, by the summer, grass pollen levels will be higher in the Northeast and the mid-Atlantic, AccuWeather noted. Warm air and rain in the regions will allow for grass to quickly grow. "Grass pollen starts as tree pollen starts to wane and can begin along the Gulf Coast as soon as April when grass starts to grow," Reppert added. "It can last through the summer and into the early fall before the sun angle starts to decrease low enough or a frost occurs." And, the highest weed pollen levels are expected across the Plains, Carolinas, and the Gulf Coast, with moisture from tropical storms and hurricanes making the season last even longer there. To the West, lower weed pollen levels are projected across the Northwest thanks to drier weather and early-season cold air. But, 22 states in a 2,000-mile zone stretching from the Northwest to the Gulf Coast will see higher tree pollen levels, including Washington Idaho, Colorado, Tennessee and Florida. High pollen levels are expected through most of the spring in the Pacific Northwest and Rockies states. Climate change has something to do with it AccuWeather points out that a warming spring is creating longer growing seasons and an earlier start to the allergy season. A recent new report from non-profit Climate Central says that millions of Americans in most major cities are suffering from earlier, longer, and more disruptive allergy seasons amid the effects of human-caused climate change. 'Many allergy sufferers have noticed their symptoms worsen over the past decade. The trend of more intense allergy seasons getting a jump start earlier in the spring and lasting later into the fall follows the overall trend line of warmer and wetter spring seasons in America,' AccuWeather Senior Meteorologist and Climate Expert Brett Anderson explained. 'There will be variability year to year depending on spring temperatures, storm tracks, and additional moisture from tropical storms and hurricanes, but the overall trend is clear,' he said. 'Pollen counts are on the rise and seasonal allergies are getting worse for millions of people as our climate continues to warm.'
