Hurricane Dolly is about to come on shore in south Texas, the reports I am hearing say the biggest threat is not from the wind but from the rain. They have been saying that if they get the amount of rain they are expecting in south Texas the levies that protect them from the Rio Grande river will not hold and there will be major flooding. The levee systems we have in place here in America are old and do not work. It seems like the government needs to get another system in place to protect us from flooding rivers.
