Weather Alerts and Warnings for Riverside

Air Quality Alert

Air Quality Alert issued November 30 at 7:32AM PST by NWS San Diego CA
Nov 30, 7:32 AM Dec 1, 7:45 AM
WHAT: The South Coast AQMD has extended a mandatory wood-burning
ban for residents in the South Coast Air Basin. The No-Burn rule
bans burning wood, pellets, and manufactured fire logs in any indoor
or outdoor wood-burning device.

WHERE: The South Coast Air Basin, which includes Orange County
and non-desert portions of Los Angeles, Riverside, and San
Bernardino counties. No-Burn Day alerts do not apply to areas above
3,000 feet in elevation, the Coachella Valley, or the High Desert.
Homes that rely on wood as a sole source of heat, low-income
households and those without natural gas service also are exempt
from the requirement.

WHEN: until 11:59 PM Sunday.

IMPACTS: Particles in smoke can get deep into the lungs and cause
health problems (including asthma attacks), increases in emergency
room visits, and hospitalizations. No-Burn Days are needed to
protect public health when fine particle pollution levels are
expected to be high anywhere in the South Coast Air Basin. No-Burn
Days are based on fine particle pollution levels that are forecasted
for an entire 24-hour period, which may not be reflected in
real-time air quality maps.

Run your air conditioner and/or an air purifier and avoid using devices that bring in outside air like a swamp cooler or whole house fan if you have other ways to stay cool. Additional details for this air quality alert are available at www.aqmd.gov/advisory. Information on the South Coast AQMD Check Before You Burn program is available at www.aqmd.gov/cbyb.
