An intensely hot summer in the United States shows signs it could bleed into the new season — a trend as the world warms from fossil fuel pollution.
An excessive heat watch is set across western Pima County later this week. And temperatures in Tucson could reach 105 degrees by Friday, the weather service says.
Corn sweat is the process by which corn plants release moisture into the air to stay cool, and it brings the Midwest a surge in humidity every summer.
It's been a wild week of weather in many parts of the United States, from heat waves to snowstorms to flash floods.
Tucson monsoon season so far: Wet, hot and sometimes wildFor Star subscribers: The city normally gets 5.69 inches in a typical monsoon season. With about 40 percent of the season still left, Tucson has already received about 95% of its typical monsoon rainfall total.
First responders launched high-water and helicopter rescues of people trapped in cars and homes in rural New York and Pennsylvania.
A strong storm Thursday that knocked over trees and power poles Thursday evening hit Tucson's east and west sides, officials say.
Tornadoes spawned by Tropical Storm Debby leveled homes, damaged a school and killed one person early Thursday, as the system dropped heavy rain and flooded communities across North and South Carolina.
A spot near Lake City in Florida led the nation in total rainfall from Debby at 19.67 inches, according to the Weather Prediction Center.
Tropical Storm Debby drenched cities in Georgia and South Carolina Tuesday in what is just the beginning of a prolonged storm that could dump up to 25 inches of rain.
Thunderstorms are possible this afternoon in the metro Tucson area as well as blowing dust in some of the area's outskirts, the weather service says.
Tucson's newest cooling center in the Mission Annex facility at 1801 South Mission Road will be open seven days a week, officials say.
