The National Hurricane Center is calling Hurricane Harvey life-threatening and said its track may keep it strong and kicking longer than they previously thought, into early next week.

The National Hurricane Center says Hurricane Harvey is expected to bring life-threatening and devastating flooding from heavy rainfall and storm surge, which is an abnormal rise of water above the normal tide.

The center says Harvey is expected to approach the middle Texas coast Friday and make landfall by that night or early Saturday. It then will likely stall near the coast or just inland through the weekend.

The updated forecast keeps Harvey as a tropical storm through midweek. The storm is expected to produce up to almost 3 feet (0.91 meter) of rain in some areas of the middle and upper Texas coast through next Wednesday. During the same period it’s expected to produce more than 1 foot (0.3 meter) of rain in far South Texas and the central parts of Texas and Louisiana.
