Dust returns to Phoenix area after hazy weekend – KTAR.com

PHOENIX — Breezy winds kicked up a blanket of dust across the Valley on Sunday, and forecasters say more is on the way this week.

Visibility in Phoenix became so bad on Sunday that Sky Harbor airport stopped flights for over an hour

The wind and dust peaked Sunday afternoon and gradually improved into the evening, said Michael Graves, an air quality meteorologist with the Arizona Department of Environmental Quality.

“You might’ve seen the mountains a bit obscured in the distance,” Graves told KTAR News 92.3 FM on Monday. “A lot of haze in the air.”

By Monday morning, skies had largely cleared and dust levels near the ground had dropped significantly.

Expect more gusty, dusty days this week

The relief may be short-lived.

ADEQ is watching for increased afternoon breezes Tuesday, Wednesday and Friday, this time from the west and southwest. Though the winds are expected to be weaker than Sunday’s, Graves said forecasters cannot rule out dust.

“I wouldn’t say windstorm,” Graves said. “I would just say we’ve got some waves coming in. They’re going to increase our afternoon breeziness.”

It’s enough to kick up dry, exposed dirt, which could create pockets of dust. There is a slight chance of broader regional dust transport, Graves said.

It will impact people with asthma, COPD or respiratory conditions the most. Graves advised those with issues to monitor conditions and stay indoors during the dustiest hours.

“If you’re going to be outside, be outside during the times when it’s less dusty or hazy,” Graves said.

Graves noted that spring weather systems typically pass to the north of the Phoenix area, delivering wind and slight temperature drops but little to no rain, a pattern likely to continue.
