Two hurricanes are set to hit the U.S. on Saturday while a weakening tropical storm continues to move through the Atlantic.

In the Gulf of Mexico, Hurricane Hanna, a Category 1, is making its way to Corpus Christi, Texas. In the Pacific Ocean, Hurricane Douglas, a Category 2, will weaken as it moves toward Hawaii. In the Caribbean, Tropical Storm Gonzalo is headed toward the Lesser Antilles, bringing heavy rains and strong winds.

According to the National Hurricane Center, Hanna will make landfall in the afternoon or early evening between the Texas coastal cities of Corpus Christi and Brownsville. Hanna has prompted flood alerts for areas around the Mexico-Texas border as well as parts of southwestern Louisiana.

Forecasters are predicting 12 inches of rain and heavy winds over the weekend in South Texas, with 3-5 inches expected in upper Texas and Louisiana. Experts also predict that some strengthening is possible before Hanna reaches land.

“It could cause some damage to homes,” Brian Field, a National Weather Service forecaster in Corpus Christi, said. “There is obviously a potential for downed trees, power lines and things like that.”

On Sunday, Douglas is expected to move across Hawaii's island chain with near hurricane strength and around 6-10 inches of rain in some regions. Gov. David Ige has already issued a state of emergency as forecasters warn of strong winds and heavy rainfall hitting the entire state. Hawaiian Airlines has also canceled all flights on Sunday.

"Recent model trends indicate a northward shift to the path of the hurricane. Regardless of its exact track and whether it makes a direct landfall, severe impacts are still anticipated across the islands as the threats extend well away from the storm's center," CNN meteorologist Derek Van Dam said. "Hurricane-force winds extend 25 miles from the center and tropical-storm-force winds extend outward up to 105 miles, meaning this doesn't need to be a direct landfall to have serious consequences."

Tropical Storm Gonzalo has weakened Saturday morning as it neared the Windward Islands but continues to bring heavy rain and 40 mph winds to the region. The National Hurricane Center said Gonzalo could dissipate altogether by Sunday.
