One of my favorite tracking sites is www.stormpulse.com which lets you choose which storm to track, and can see how far away it is in miles from some city (like San Antonio or Corpus Christi, etc.).
Currently as of 08/17, this tracking authority apparently does not envision a high chance of Hurricane Bill coming to Texas, but instead predicts that it will be heading toward the eastern US coast. Bill turned into a Hurricane status as of the morning of 08/17.
Of course, the true official hurricane forecast site is always the National Hurricane Center from the National Weather Service.
