Smoke will be visible for days or possibly weeks in south-central Arizona where crews continue to strengthen the perimeter around a wildfire.

Nearly 1,000 firefighters focused Sunday on monitoring and mopping up the fire lines around the blaze south of Superior.

Fire officials say the Telegraph Fire, which has burned nearly 138 square miles (357 square kilometers), is 76% contained.

Two wildfires fueled by dry weather have been growing in south-central Arizona, forcing evacuations.

The so-called Telegraph Fire has now expanded to more than 95.6 square miles (247.7 square kilometers) and is at zero containment, authorities said late Monday. Officials had said a forecast of low humidity and high winds throughout the week will likely facilitate more spread.
