Forecasters said Hurricane Harvey, a category 2 storm in the Gulf of Mexico, is expected to intensify into a Category 3 hurricane, as it makes landfall late Friday or Saturday.
It is possibly the biggest storm to hit mainland US since Hurricane Wilma in 2005.
Forecasters predict the storm may cause sea levels to surge 12-ft and dump "life-threatening" amounts of rain in Texas.
