Houston Executive Airport is one of three hubs the Texas Army National Guard is operating from.
The storm caused damage throughout the region, flooding homes and leaving at least 30 dead. Two twin-engine CH-47 Chinook helicopters from the Nebraska National Guard have already spent the past few days hauling relief crews and thousands of pounds of supplies around Texas.
"We were an island like everyone else", said Tom Branch, coordinator for Liberty County's Office of Emergency Management.
The state has an agreement in place with Louisiana, Texas and several other surrounding states to offer Guard support in disaster scenarios.
