An Extreme Heat Warning means that a period of very hot temperatures, even by local standards, will occur. Actions should be taken to lessen the impact of the extreme heat. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible and drink plenty of water.

Air Quality Alert

Air Quality Alert issued August 6 at 9:42AM MST by NWS Phoenix AZ
Aug 6, 10:42 AM Aug 6, 10:00 PM
AQAPSR

The Arizona Department of Environmental Quality (ADEQ) has issued a
PM-10 High Pollution Advisory for the Phoenix Metro Area today.

Lingering dust from last night has resulted in high local PM-10
concentrations that pose a health risk. Adverse health effects
increase as air quality deteriorates.

Coarse particulate matter - also known as PM-10 - is an air
contaminant that can aggravate heart and lung disease conditions,
especially in older adults, children, and those with asthma. A
decrease in physical activity is recommended.

Consolidate your travel, stabilize loose soils, slow down or avoid
travel on dirt roads, reduce or eliminate fireplace use, and avoid
using gas-powered lawn equipment.

For details on this High Pollution Advisory, visit the ADEQ internet
site at www.azdeq.gov/forecast/phoenix or call 602-771-2300.
