From Southwest Gas:
Tucson and Sierra Vista Customers Experiencing Outage.
Due to the unusually cold weather throughout many parts of the country, Arizona's natural gas supply has been impacted.
In the Tucson area, natural gas customers in the Rita Ranch and eastern foothills areas, and those in the Sierra Vista area south of Buffalo Soldier Trail, on both sides of Highway 92, and running south to Hereford, have been impacted.
If you live in these areas, you do not need to notify Southwest Gas because we are currently working to restore service as soon as possible.
When service is being restored to homes and businesses, Southwest Gas personnel will directly contact customers. At that time, they will need access to the natural gas meter and entry. Also, inside and outside lights must be on and an adult home during the dark, evening hours.
Customers who currently have natural gas service are asked to conserve on Thursday and Friday while service is being restored.
