Showers ahead this weekend after storms that slammed southern Massachusetts Friday

Scattered showers are expected throughout the state Saturday night and Sunday, on the heels of the thunderstorms and heavy wind that pounded South Massachusetts on Friday evening and Western Massachusetts Saturday afternoon.

The National Weather Service forecasts hot and humid temperatures with a 50 percent chance of thunderstorms throughout the weekend.

“We’ve had some very heavy downpours,” said Charlie Foley, a National Weather Service meteorologist.

But Bay State residents, who were battered Friday night with storms, will not have to tough it out for much longer -- storm clouds are expected to be gone by Monday.

“We’ll see an end to this unpleasant weather on Monday or Tuesday,” Foley said.

Heavy rain, wind, and thunderstorms prompted flash flood warnings throughout the Commonwealth Friday night. A tornado watch from the National Weather Service was lifted around 9 p.m.

In Fall River, the emergency room of St. Anne’s Hospital had to be relocated due to flooding, forcing 18 patients to a makeshift ER on a higher floor.

“There was just so much rain over such a short period of time,” said Wendy Bauer, a hospital spokeswoman. “The clean-up process is still continuing.”

Cleaning crews worked through the night to drain the water and sanitize the hospital, Bauer said. The emergency room was reopened at 7:30 a.m.

In East Bridgewater, two men were rescued Friday night after their canoe capsized on Robbins Pond. East Bridgewater Fire Department Lieutenant Keith McCartney said the men were caught in the hard rains when their canoe overturned. Rescuers used a hovercraft to reach them.

One was found inside a canoe, which the man had managed to re-enter, and another was located on a nearby island that he had reached after swimming.

The men, James Martin, of East Bridgewater, and Jesse Darling, of Halifax, declined medical treatment.

A microburst that featured winds between 70 and 80 miles per hour tore up trees in a small section of Taunton Friday, the Weather Service reported Saturday based on a preliminary storm survey. The microburst was about 600 feet wide, according to the Weather Service, and it affected an area around Tremont Street

According to the National Weather Service’s website, microbursts are strong downdrafts with high winds that generally last less than five minutes.

High winds from the storm caused 13,200 National Grid residents to lose power through parts of Friday night and into early Saturday morning. By 1:30 a.m. Saturday all power had been restored.

National Grid spokeswoman Jackie Barry said a large tree limb fell onto electrical lines on Chelmsford Street in Lowell, causing 1,200 residents to lose power from 6 to 8 p.m.

Around 6:20 p.m., a high voltage line in Bridgewater was struck by lightning, leaving 12,000 residents in parts of Bridgewater, East Bridgewater, Brockton, Hanson, Halifax, and Pembroke without power for parts of the night.

Barry said that around 1:30 Saturday morning, about 470 customers in Halifax and Bridgewater were the last to have their power restored.
