How has Hurricane Harvey managed to stay in the Southeastern Texas area so long when other Hurricanes crawling up the East Coast seem to go right through one place to the next at a quicker rate?

I went through Hurricane Matthew last year, and it seemed to pass through us in about half a day. Harvey seems to be in the same general area it's been for the last 2+ days.

It ran into a high pressure system to the west that prevented it from moving more inland, and to an extent, is sandwiched between another high pressure system to its southeast, just kind of holding it in position.  It is eventually going to slowly move to the east/northeast as it dissipates, but will dump tons more rain on the Houston/south Texas area before doing so.
