holding the line that they have already been able to create in some way on the north end using kind of a back burn operation as well as throwing down fire retardant. they do have a lot of resources as you mentioned here today. that's been a big improvement over what they had here yesterday. at least 800 fire personnel. 15 hotshot crews. we're expecting to see five more hotshot crews arrive here in the next few hours. we also know they had five helicopters up working, three air tankers. they're throwing everything they have at this right now, brianna, in the hopes of keeping this fire under control. we're sitting at just under 5,000 acres. that number has not gone up in the last 24 hours or so. but, again, it's still an unpredictable situation. we're going to keep watching it for you. >> and do we have any sense of how this started, ana? >> we don't know specifically. fire officials say they're still investigating. but they believe it is human-caused.
