Cape Cod and parts of the South Shore, battered by long power outages during last weekend’s storm, could see up to 10 additional inches of snow and gusts of wind at 50 miles an hour Sunday, said Alan Dunham, a National Weather Service meteorologist.

Officials from NStar, which had 350,000 customers without electricity last week, many of them on the Cape and South Shore, are planning to have extra crews available.

“We’ll be staffing our service center throughout the storm to make sure our communities are well served,” said NStar spokeswoman Annemarie Walsh. “We’re prepared.”

About 6 to 8 inches of snow are expected in the Boston area and North Shore Sunday, along with wind gusts of 40 to 45 miles an hour, Dunham said.

But a National Grid spokeswoman said the utility is not expecting storm-related damages as severe as they saw last weekend, when 251,000 customers lost power.

Still, the company will have extra crews on hand and contractors standing by tonight, said spokeswoman Debbie Drew.

“We’re keeping a close eye on the South Shore and the southeastern area of the state because that’s where the strongest wind gusts are expected,” she said.

Today’s snow left only trace amounts of accumulation in Boston, with most of it melting as soon as it hit the ground.

In Dorchester today, Guelmison Ribeiro could finally walk down his street without having to slog through piles of snow from last week’s storm. Some roads near his workplace in Weston still aren’t cleared, he said, and he’s not ready for more snow.

“I’ve been late to work all week because of delays on the bus,” said Ribeiro, 23, who said he has been hiking an extra mile to avoid walking along busy highways with unplowed shoulders.

His commute from his home on Brook Avenue to Weston typically takes about two hours, even without snow.
