Thousands of people in the area are waking up without power.

Austin Energy says up to 50 pole fires sparked overnight due to dirt and moisture on equipment, causing power outages for about 4,000 customers.

Experts say the mist in the air Friday morning turned dust on electric Poles to mud, which created the sparks.

There have also been reports of outages for Pedernales Electric customers. Officials ask those customers to call 888-883-3379 to report an outage.

Austin Energy says 16 crews are working to restore power in 32 locations.
