Hurricane Florence aftermath: Mass. communities most at risk for flash flooding

BOSTON — As the remnants of Florence move into New England Tuesday, we’re on alert for the risk of flash flooding.  The National Weather Service has issued a FLASH FLOOD WATCH with widespread rain amounts on the order of 1-3”, much of which could fall in one to two hours.  Some neighborhoods could see as much as 4-6” before the rain tapers off late Tuesday afternoon and into the evening.

While our greatest concern will be for urban flooding and ponding of water on the roads, there is a low risk for small river and stream flooding.  Recent rains have our rivers running higher than normal.  With high rain rates and deep tropical moisture in play, we’re watching a few locations in particular for the risk of minor flooding.

One of those spots is the North Nashua River at Fitchburg.  When minor flooding occurs, some businesses at the Depot & River St. merger are at risk.  The probability of minor flooding is low, in fact model simulations indicate only a 14 percent chance to exceed minor flood stage.  Nonetheless, with some uncertainty to how much rain will ultimately fall here, if you live in this area it’s a good idea to stay weather aware.

Another area that could experience flooding is along the Squanacook River in Townsend.  The intersection of Turnpike and Barker Hill Rd. is a prone location, and residents here may need to watch for rising water.
