Heat, ozone to get excessive this week

High pollution and heat warnings are in place this week for Maricopa, according to the National Weather Service.

Pinal County Department of Air Quality issued an ozone high pollution advisory for today and Wednesday. This means forecast weather conditions combined with existing ozone levels are expected to result in local maximum eight-hour ozone concentrations that pose a health risk. Adverse health effects increase as air quality deteriorates.

Ozone is an air contaminant that can cause breathing difficulties for children as well as persons with respiratory problems. A decrease in physical activity is recommended.

Meanwhile, NWS issued an excessive-heat warning, in effect from noon Wednesday to 8 p.m. Thursday. Afternoon temperatures are expected between 103 and 113 in western Pinal County.

An excessive heat warning means a period of very hot temperatures, even by local standards, will occur. Actions should be taken to lessen the impact of the extreme heat.

The high temperature Wednesday is expected to be 111, with little wind. Thursday, the expected high is 112.

Stay indoors and seek air-conditioned buildings. Drink water, more than usual, and avoid dehydrating alcoholic, sugary or caffeinated drinks. Dress for the heat – lightweight and light-colored clothing. Eat small meals and eat more often.

Monitor those with a higher vulnerability to heat, including small children. Check in on family, friends and neighbors, especially the elderly. If engaging in outdoor activity, take longer and more frequent breaks and avoid the hottest parts of the day.

Never leave kids or pets unattended in cars.
