Mass. rainfall totals: ‘1 in 200’ weather event floods South Shore
Local meteorologists called the storm affecting the South Shore a historic weather event. Here’s where got the wettest.
With a deluge of rain coming down in the Boston area Thursday, some meteorologists called the storm affecting the South Shore a historic “one in 200” weather event.
Here’s what parts of the metro region got the wettest.
Thursday’s storm hit hard in Boston, Quincy, Brockton, and other South Shore communities, which were under a flood watch in the morning, the National Weather Service said. NWS also issued a flash flood advisory for Rhode Island, eastern Massachusetts and parts of Connecticut that stretched into the afternoon.
Some lanes of I-93 were impacted by the rain in Milton, Canton, and Quincy, with flooding affecting commuters and workers across the state.

Along the border of Hingham and Weymouth, multiple measurements put the rainfall at around 6.5 inches, according to Boston News 25 meteorologist Tucker Antico. That amount categorizes the storm at a one in 200 years rainfall event.
“To add some perspective, that is only 1/3rd the rainfall that brought about the tragic flooding in Texas,” Antico noted on X. “More importantly, the terrain in that part of the country enhances the danger massively.”
WBZ Chief Meteorologist Eric Fisher echoed the one in 200 event calculation, adding that six inches rain on parts of the South Shore has a .5 percent chance of falling in a given year.
Terry Eliasen, another meteorologist with WBZ, shared rain totals for towns south of Boston, including more than five inches in Braintree, more than six in North Hingham, and nearly 6.5 inches in Weymouth.
