From the National Weather Service:
Latest Rainfall Forecast:
The highest totals of 2-4" are expected in Rhode Island and southeast Massachusetts with up to 5" in a few spots. Heavy rain comes in bands, so not everyone in those areas will see these totals. Rainfall totals will be much lower farther west.
Be alert for urban flooding thru tonight in Rhode Island and central and eastern Massachusetts, where a Flash Flood Watch remains in effect.
