A power outage has left thousands of people without electricity in west Alabama with temperatures in the teens.

Alabama Power Co. spokesman Joseph Brown said a main transmission line failed about 5:10 a.m. Wednesday. That knocked out power to about 19,200 customers in parts of three western counties as temperatures hovered around 15 degrees.

Brown says it’s unclear whether the outage was linked to the frigid weather.

Crews are working to get the power back on.
