WASHINGTON (AP) — U.S. retail sales rose at a solid pace in October, though the gains were boosted by one-time factors such as hurricane recovery spending and higher gas prices.

Retail sales rose a seasonally adjusted 0.8 percent last month, following two months of slight declines, the Commerce Department reported Thursday. Excluding gasoline sales, which were inflated by higher prices, sales climbed 0.5 percent.

The figures suggest that consumers are pulling back a bit on their spending, which is likely to slow growth in the final three months of the year. Americans had lifted their spending over the summer and fall at the fastest six-month pace in four years. Yet business spending on machinery, computers and buildings barely increased in the July-September quarter, leaving consumers shouldering more of the burden of maintaining growth.

Economists saw Thursday's report as evidence that Americans won't be able to spend as freely in the fourth quarter as they did in the previous two. Excluding volatile categories such as gas, auto and food services, retail sales rose just 0.3 percent.

"This looks very much like the end of the boost from the tax cuts, and it strengthens our conviction that (economic) growth has peaked," Ian Shepherdson, chief economist at Pantheon Macroeconomics, wrote in a research note.

Most analysts forecast economic growth will slow in the final three months of the year, to a roughly 2.5 percent pace, after robust increases of 4.2 percent in the second quarter and 3.5 percent in the third.

Investors also registered their disappointment as they sold off stocks of retail companies, including Walmart, despite the fact that the company reported healthy earnings Thursday. Walmart shares fell 2.2 percent in midday trading, while Target's fell 3.5 percent. Home Depot, which continues to register huge sales, also dropped 2.2 percent.

Jerome Powell, chairman of the Federal Reserve, said Wednesday night that there are clear risks to the economy on the horizon, including the cumulative effect of the Fed's own interest rate hikes. It is on track to lift the short-term rate it controls a fourth time this year at its December meeting.

The positive impact of the Trump administration's tax cuts, as well as a large spending package approved by Congress this spring, will likely fade over the next year, Powell said.

Some of October's spending gain was likely boosted by the impact of Hurricane Florence in September and Hurricane Michael last month. The government said it could not measure the precise impact of the two storms. But auto sales rose 1.1 percent in October, the most since March, as many Americans may have replaced cars destroyed by the hurricanes.

Home improvement and garden store sales increased 1 percent, the most since May, likely boosted by storm-related home repairs and preparations. On Tuesday, Home Depot breezed past all expectations for its most recent quarter and raised its annual profit expectations.

Gasoline station sales jumped 3.5 percent, the most in almost a year, largely because of rising prices at the pump. Yet prices have since declined and will likely continue to do so, as oil prices have fallen sharply this week. The average cost of a gallon of gas was $2.67 on Thursday, down from $2.89 a month earlier.

Nearly all types of retailers reported strong sales gains, a sign of consumer health. Clothing store sales rose 0.5 percent and sales at general merchandise stores, which include big box retailers such as Walmart and Target, also increased 0.5 percent. Electronic and appliance store sales rose 0.7 percent.

Restaurants and bars posted a rare decline for the third month in a row, falling 0.2 percent, following a sharper fall of 1.5 percent in September.
