All rail and subway lines in Boston were suspended from Monday evening until Wednesday as the city braced for a massive storm, which has already dumped 20 inches in the last 24 hours. Boston City Hall and public schools were also closed for the second day in a row. The city has recorded a new 30-day high of 72.6 inches, with 64.4 inches falling in the past 14 days alone. Massachusetts Gov. Charlie Baker declared a state of emergency as six or seven feet fell in parts of the state. Some places already feeling the brunt of three storms in the past two weeks will get 70 to 80 inches of snow. Three buildings collapsed Monday morning. While the region is expected to get a brief reprieve Wednesday, it is expected to be hit with another storm that could bring “significant” snowfall on Thursday or Friday.
