The U.S. economy unexpectedly maintained a brisk pace of growth in the third quarter as an increase in inventory investment and a smaller trade deficit offset a hurricane-related slowdown in consumer spending and a decline in construction.

Gross domestic product increased at a 3.0 percent annual rate in the July-September period after expanding at a 3.1 percent pace in the second quarter, the Commerce Department said on Friday.

The department said while it was impossible to estimate the overall impact of hurricanes Harvey and Irma on third-quarter GDP, preliminary estimates showed that the back-to-back storms had caused losses of $121.0 billion in privately owned fixed assets and $10.4 billion in government-owned fixed assets.

Harvey and Irma struck parts of Texas and Florida in late August and early September. Hurricane Maria, which destroyed infrastructure in Puerto Rico and the Virgin Islands, had no impact on third-quarter GDP growth as the islands are not included in the United State’s national accounts.
