MASSACHUSETTS EMERGENCY MANAGEMENT AGENCY 

SITUATIONAL AWARENESS STATEMENT 

JULY 28, 2016 

9:30 PM 

The National Weather Service in Taunton has provided the following forecast information for tomorrow (Friday).              

Situation:

A FLASH FLOOD WATCH has been issued for Connecticut, Rhode Island, and Southeast Massachusetts with the expectation for a heavy rainfall and potential flash flood event beginning early morning Friday and ending in the late afternoon on Friday.  Thunderstorms are possible in some areas, and thunderstorms could include a tornado or waterspout. 

    Details: 

  • Widespread rain will impact southern portions of New England beginning early morning Friday and ending in the late afternoon Friday.
  • Heaviest rain is expected in the areas covered by the Flash Flood Watch.  In these areas, and especially areas closer to the south shoreline of New England, rainfall amounts will average around 1 to 2 inches with locally heavier amounts up to 2 to 4 inches.  Rainfall may fall at some times and in some areas at rates of 1 to 2 inches per hour.
  • Embedded thunderstorms are possible, especially closer to the south coast of New England and across the adjacent southern waters.
  • Impacts may include flooded roadways and basements with an accompanying threat to life and property.
  • There is a possibility of a tornado or waterspout, especially along the south coast of New England and across the adjacent southern waters.
  • The risk of flash flooding is highest in urban areas.  The risk that streams and rivers will overflow and flood is significantly lower.
  • Areas of uncertainty in the forecast include:
    • Locations that will receive the highest rainfall amounts: forecast guidance continues to wobble north and south with respect the heaviest axis of rainfall.
    • Exactly how much rain will fall in any particular area.
    • Whether northern portions of Massachusetts that are currently experiencing severe drought will be completely shut out from rainfall.
