The National Weather Service has issued a Flood Watch for Belmont and communities in eastern Massachusetts that will last until 5 p.m. on Tuesday, Sept. 6. Rainfall amounts of three to five inches are expected over much of southern New England with localized amounts of five to seven inches or more.

During this period, flooding caused by excessive rainfall continues to be possible.

Earlier Monday, the NWS issued a Flash Flood Warning for most of northern Massachusetts before downgrading it at 10:47 a.m. on Monday, Sept. 5. A Flash Flood Warning is issued when a flash flood is imminent or occurring. If you are in a flood prone area move immediately to high ground. A Flood Watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.

Flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as
other poor drainage and low-lying areas is possible and citizens should stay vigilant.

Locations that will experience flash flooding include Belmont, Cambridge, Newton, Somerville, Waltham, Arlington, Watertown, Lexington, Tewksbury, North Andover, Melrose and Saugus.

The NWS warns drivers to “Turn around, don’t drown” when encountering flooded roads. Most flood
deaths occur in vehicles. Be especially cautious in early morning hours when it is harder to recognize the
dangers of flooding.
