As it barrels toward roughly one-third of the U.S. oil refining capacity, Hurricane Harvey threatens to disrupt gasoline supplies and cause prices to rise nationwide.

The National Hurricane Center expects the hurricane will become a Category 3 storm with winds up to 125 mph. It could hang over the Texas Gulf Coast near Corpus Christi for as many as three days causing dangerous flooding and storm surge.
