and adults and people with lung disease such as asthma
avoid all outdoor exertion. Everyone else, especially
children, should avoid prolonged or heavy exertion
be the third consecutive day with a forecast calling for
an ozone action alert in Houston.
An air quality
monitor in southwest Houston Friday afternoon
read 201 parts per billion for ozone, the highest
one-hour spike in Houston and Texas since Oct. 23, 2003.
The reading is “very unhealthy.” The one-hour standard
for ozone is 125 ppb.
readings are occurred despite fewer cars on the road. A

88 percent in Houston because of the storm: https://www.geotab.com/blog/hurricane-harvey-telematics-data-timelapse/.
