UPDATE 2-UPS resumes operations in some parts of storm-battered Texas

(New throughout, adds details on company operations)

Aug 31 (Reuters) - United Parcel Service Inc said on Thursday it resumed operations some parts of Corpus Christi, and Austin, Texas, that it had halted as Hurricane Harvey barreled down on the U.S. Gulf Coast.

UPS, the world's largest package delivery company, has restored service to more than 150 zip codes in Texas over the last 24 hours though operations remained at a standstill in storm-battered Houston and other Gulf Coast areas, UPS spokesman Matt O'Connor said. Two days ago, the storm had stopped or sharply limited deliveries to more than 730 zip codes in Texas and Louisiana, he said.

"The safety of our employees comes first and we will be resuming service as soon as it is safe to do so," O'Connor said. "In Houston, that will come down to local areas that were impacted and how quickly water subsides."

Harvey came ashore over the weekend as the most powerful hurricane to hit Texas in a half-century. Days of heavy rains and flooding of streets, highways, and rail networks forced UPS and rival FedEx Corp to shutter facilities and cease delivery to huge swaths of southeast Texas and Louisiana.

UPS halted operations in Austin, northwest of Houston, and Corpus Christi, along the coast, before Harvey made landfall, O'Connor said.

"Now that the weather is subsiding in communities in Corpus Christi, and our employees are able to come back home, we will continue to resume service as it is safe to do so," O'Connor said. (Reporting by Eric M. Johnson in Seattle; Editing by Paul Simao and David Gregorio)
