Live updates: Crews remove Tracy Medline facility's walls to tackle interior hotspots, officials say

In addition, the San Joaquin Valley Air District issued an air alert due to smoke from the fire, which is billowing over parts of San Joaquin and Stanislaus counties.

Winds in the area are expected to send smoke inland and southward along the western and central portions of the San Joaquin Valley Thursday evening and overnight, according to the air agency.

More information is available at Valley Air's website.

Jamie Holt, with the San Joaquin Air Pollution Control District, spoke about how the smoke from the Medline facility fire in Tracy may impact the air quality.

Jamie Holt, with the San Joaquin Air Pollution Control District, spoke with ABC7 Eyewitness about how the smoke from the Medline facility fire in Tracy may impact the air quality.

Holt said the air quality in the area still considered good but does recommend those considered "sensitive" and "at-risk" to take precautions as the evening hours approach, such as turning on air purifiers and/or HVAC units, closing windows and wearing an N95 mask if you can smell smoke.

She said the air district did not consider any of the supplies in the burning warehouse to be toxic to the air quality.

After the fire is put out, Holt said residents should see improved air quality. While smoke will dissipate, she did say it will start to travel south of Tracy due to the winds, and may hit some communities in that direction.

Chief Bradley also mentioned that fire hydrants were not providing good pressure, which hindered their ability to attack the fire.
