PHOENIX — Monsoon storms are likely to continue across Arizona, with hot and humid weather expected throughout the week.
The greatest storm potential will be in the higher areas of northern, eastern and southeastern Arizona, but more storms are also possible in the valleys as these mountain storms move in our direction each day.
Any storms that occur could produce strong winds, dangerous lightning, small hail, heavy downpours, and flooding, especially along and near wildfire burn tracks. Therefore, please remain aware of weather conditions and do not attempt to drive through flooded swales or roads.
Dust is also a risk as storms can whip up high winds in some of our open desert areas. We could see that happen today, especially south of Phoenix as the storm moves off higher terrain. A Dust warning Today from 4 to 8 p.m. for parts of the South Valley, including the cities of Ahwatukee and Queen Creek, as well as most of Pinal and Pima counties . Blowing dust or sandstorms can reduce visibility to less than a mile, so if you're stranded on the road when dust hits, remember to “pull over and stay active.”
Valley highs will continue to rise above 110 degrees each afternoon, with overnight lows only cooling into the 80s to 90s each day.
Lingering monsoon moisture can also make things feel hotter, as the heat index, or “feeling” temperature, is about one degree higher than the air temperature.
overheating warning The ban is in effect throughout Mohave County, including places like Bullhead City and Lake Havasu City, until Wednesday night.
overheating warning The lower Colorado River will also continue into Friday night. That includes Yuma. The heat index in this area of Arizona could reach 115 to 120 degrees this week.
As temperatures continue to be hot across the valley and across the state, the risk of heat stroke and heat-related illness remains.
Limit time outside, especially in the afternoon when the day is hottest. Stay hydrated with water and electrolyte drinks, and never leave children or pets alone in the car, no matter how fast the task is.
Air quality will also be an issue this week. one High ozone pollution warning Effective Wednesday through Wednesday in Maricopa and Pinal Counties Ozone high pollution watch Thursday and Friday have been released. These may be upgraded to recommendations as we get closer.
People most vulnerable to the effects of air pollution include children, older adults, adults who exercise outdoors, people with heart or lung disease, and people with asthma and bronchitis.
Ozone exposure can increase the number and severity of asthma attacks, cause or worsen bronchitis or other lung diseases, and reduce the body's ability to fight infections.
We can all help prevent the pollution problem from getting worse by sharing rides, using public transport or working from home. Also, refuel your vehicle after dark to avoid idling in long drive-thru lines.
