874 WGUS61 KBOX 301912 FFABOX URGENT - IMMEDIATE BROADCAST REQUESTED Flood Watch National Weather Service Boston/Norton MA 312 PM EDT Mon Aug 30 2021 .Remnants of Ida will approach and track near southern New England, with heavy rain and flooding possible late Wednesday into Thursday. Early indications are for the potential of 2-4 inches of rainfall, with locally higher amounts possible. Given recent rainfall resulting in small rivers and streams already running above normal, there is an enhanced risk for flooding late Wednesday into Thursday. There remains some uncertainty on the axis of heaviest rainfall. A shift of 50 to 100 miles in the forecast track of the remnants of Ida, will impact the exact location of heaviest rainfall. Stay tuned to later forecasts.
