For those who don't like being hit by high-speed vehicles, or worse doing word problems, USGS has a webcam on MK pointed across at Mauna Loa so you can track the lava from the safety and comfort of your at-home lava viewing area.

The furthest advanced flow of lava has crossed the Mauna Loa Observatory road overnight.

If this flow further develops it looks like it would approach Saddle Road right around Pu'u Huluhulu / MK Access Road, and could pool there as it is quite flat, but has downhill paths both to the west and east. See 1843 and 1935-36 flows, with the 1935-36 flow being the more likely as USGS has the flow placed in the Kaumana inundation zone.
