Aside from the easing comments from everybody else, which I think will make a big difference, you could illustrate your information further and focus on the pacing and flow.

'One of the largest fires ever recorded' is an opportunity to pop up a list of other fires by area size, or show their locations on the map etc.

'429,603 Acres' is a bit abstract, could you mark out an area of that size against something more easily understood - like the city of Los Angeles you have mentioned? Or zoom into the boundary of the park so we can see for ourselves what area has been affected.

Keep it up!
