SoCal heatwave triggers air quality alerts from AQMD

LOS ANGELES (KABC) — Southern California is expecting a late summer heatwave this week that will likely result in unhealthy air quality in many parts of the region.

The South Coast Air Quality Management District issued an ozone recommendation as of Tuesday, indicating that inland communities should expect poor air quality. The worst air is in the afternoon hours in parts of the San Bernardino Mountains and the San Bernardino Valley.

The recommendation is valid from Tuesday 30 August to Sunday 4 September.

Higher temperatures lead to more emissions of dangerous chemicals that cause ozone formation, the agency says.

“This long and intense heatwave is likely to result in unusually high and sustained ozone levels,” the agency says.

Ozone pollution can be particularly dangerous for vulnerable populations – children, older adults and people with respiratory diseases such as asthma.

For a list of the most vulnerable communities, see AQMD statement here.

FORECAST: SoCal expects the hottest heatwave of the year

The National Weather Service issued an excessive heat warning for parts of Southern California from Wednesday morning through Monday evening.

The hottest temperatures reach inland valleys and deserts.

People are advised to drink plenty of fluids, stay indoors in air-conditioned rooms and check on relatives and neighbors who may be at risk.
