YARNELL, AZ - Containment on the Arizona wildfire that killed 19 firefighters over the weekend has nearly doubled.
Fire officials say the Yarnell Hill Fire is 80 percent contained, up from 45 percent earlier in the day Thursday.
On Sunday, violent winds took the Granite Mountain Hotshots by surprise and killed 19 members of the elite crew.
Friday morning, Vice President Joe Biden announced that he will travel to Arizona to attend the Tuesday memorial for the 19 fallen firefighters.
The fire also destroyed more than 100 homes and has burned about 13 square miles. Residents of the small town of Yarnell remain evacuated.
Red Cross shelters remain open at Yavapai Community College in Prescott and Wickenburg High School in Wickenburg.
Residents of another area called Peeples Valley were allowed to return home Thursday evening.
More than 500 firefighters continue to fight the blaze as authorities plan a memorial for the fallen firefighters on Tuesday.
Their bodies, which are in Phoenix for autopsies, will be returned home to Prescott on Sunday.
