Flash Flood Warning in Effect

May 5, 2017
The National Weather Service has issued a Flash Flood Warning for northeastern Norfolk County in eastern Massachusetts, Suffolk County in eastern Massachusetts, Plymouth County in southeastern Massachusetts, and northeastern Bristol in southeastern Massachusetts. The watch is in effect until 7:45 pm today.

Rainfall of 1 to 2 inches in an hour is expected in some areas. As a result, significant urban and poor drainage flooding is expected to rapidly form. Some locations that will experience flooding include Boston, Cambridge, New Bedford, Brockton, Quincy, Newton,  Brookline, Plymouth, Taunton, Weymouth, Revere, Everett, Braintree, Chelsea, Randolph, Needham, Norwood, Wellesley, Milton and Stoughton. 


Flooding will occur quickly and could become life threatening for those who try to drive through flooded roads or underpasses. Find alternate routes and avoid flooded areas.

Prior to Heavy Rain

  • Advise custodians to check all drains, grates and basins to ensure they are free of leaves and debris.
  • Check to see if sump pumps are working.
  • Remove dead or rotting branches that could fall and cause injury or damage.
  • Be prepared for potential power outages as a result of downed power lines.
  • Create an emergency supply kit including water, flashlight, extra batteries, first aid kit and non-perishable food.
  • Have a battery-operated radio on hand.

During Heavy Thunderstorms

  • Keep informed - listen to the radio for weather updates and information.
  • If basement floods before you have a chance to shut off electric and natural gas service, do not enter the basement. There is the possibility of electric shock if electrical wires are touching water. Contact your electric company ASAP.
  • “Turn Around-Don’t Drown” – It only takes a few inches of water to cause a vehicle to lose traction and stall; one foot will float most vehicles and two feet will carry them away.
  • Plan for extra travel time as some roads may flood and be temporarily closed.
  • Never attempt to remove a fallen tree from the roadway, especially if there are electrical wires tangled in the branches.
