Hey, listen. I live in Okinawa and we have so many hurricanes (typhoons) here it isn't even funny. Almost every structure is made of concrete reinforced with steel, and has typhoon windows and the like; a testament to the fact that we get so many storms.
Now, I think Houston may be better off becuase it is inland a bit, but if there is any chance of seeing winds from above 150, you really should leave. If your living quarters are made of concrete, have strong windows and/or shutters, you'll likely be alright, but I'm thinking wood. If it is made of wood, you are taking a dumb risk.
I lived in a place that was concrete, but with roof that was made out of wood. My family and I went through a storm with gusts up to 193, and the roof damn near came off the place. It was nerve racking. I wouldn't think twice about leaving in the face of a strong storm if the whole house was a wooden structure.
Sorry, but I care about people and don't want anything happening to you, especially if it can easily be avoided. Stuff is stuff. I understand wanting to stay, really, but anything more than a minor unjury to anyone really makes it not worth it.
If I decided to live anywhere in the U.S. that was hurricane prone, my house would be made of concrete, the best windows, plus shutters. In that case, heck no I wouldn't leave my house. Otherwise, board it up and hit the road...
Whatever you decide, I hope all goes well. The worst part is the power being out and it getting so humid and sticky; and it's normally humid and sticky here. Yuck!!! After a day or two of that, I feel like rippin' peoples heads off.
Best,
