The storm is forecast to move into Maine early Tuesday, but some early precautions were being taken. In York, at the state’s southern tip, an assistant harbormaster arranged for boats moored near the harbor entrance to move to more protected waters. Two dinghies sank at the town dock, he said, during the remnants of Tropical Storm Fred this past week.
Henri was expected to flood many areas already inundated by Fred.
In a swath of southeastern New York that was hit by Hurricane Irene in 2011, including the Catskill Mountains, small tributaries could again be filled and larger rivers could rise past their banks. In Boston, officials said they were building barriers around the city’s most vulnerable subway station and would suspend some transit services on Sunday.
Massachusetts experienced heavy rains on Thursday that required emergency workers to retrieve people from cars caught in high water. When Tropical Storm Elsa traveled up the Northeast coast earlier in the summer, New York subway riders had to navigate waist-deep waters at some stations.
Hurricane Sandy flooded subway and highway tunnels in New York in 2012, knocking out power to much of Manhattan. But Sandy was a much larger storm, devastating an area from New Jersey to Connecticut, and its size drove a catastrophic surge of seawater into New York Harbor.
Henri is not expected to have the same impact, and passengers waiting to board the ferry from Boston to Provincetown on Friday night were cautiously optimistic that their plans would not be foiled.
Gary Livolsi said he had been through a lot of nor’easters and was content simply making sure the umbrellas and cushions had not been left on his patio.
“I’m hoping they’re overestimating it, as they often do,” said Susan Mahoney, who was off to spend the weekend in Provincetown but was fully prepared to stay longer if necessary. “I brought extra wine.”
