The remnants of Hurricane Florence are expected to bring “widespread rainfall” to southern New England late Monday night through Tuesday night, according to the National Weather Service, with nearly all of Massachusetts under a Flash Flood Watch during that time.
“Widespread rainfall totals [will be at] 1-3 [inches with] localized heavier amounts up to 4-6 [inches],” forecasters said on Twitter Monday morning. “Flash flooding of urban/poor-drainage areas possible, as well as small streams/tributaries; still some uncertainty as to who will see the most.”
