If you were watching the radar on Wednesday afternoon, you probably noticed the massive storm which struck Rhode Island and parts of Southeastern Massachusetts around 4:00. This storm prompted the issuance of severe thunderstorm warnings and even tornado warnings. Here at HinghamWeather.com we were streaming live to cover the storm, something which is done only in extreme conditions.
That powerful thunderstorm, responsible for flooding rains and hail up to ping pong size, also spawned a tornado, according to the National Weather Service in Taunton.
At first the storm produced a waterspout (a tornado over water), just off of Rumstick Point in Barrington, Rhode Island. At 4:05 PM this storm moved ashore (officially becoming a tornado) in Warren. There winds are estimated to have reached 90 MPH. By 4:10 PM the tornado had reached Swansea, Massachusetts. Here it is estimated that winds reached 65-75 MPH. The storm had a path of 4.2 miles, but was only 40 yards wide. As you are aware, tornadoes are rare, but not unheard of in Southern New England. Massachusetts typically sees at least one weak tornado every year, and some years feature more than one. The tornado was rated an EF 1, the second lowest rating on the new EF tornado rating scale.
STORM TIMELINE ON RADAR

At 4:04 PM, StormTracker Radar at HinghamWeather.com indicated a tornado (indicated by the red triangle) near or over Barrington, Rhode Island. This radar estimation was excellent, since a tornado was in fact on the ground at this time in Warren.

At 4:09 PM, StormTracker Radar at HinghamWeather.com indicated a tornado had just entered Southeastern Massachusetts near Swansea. This too was an excellent estimation which was confirmed on Thursday.

At 4:14 PM, StormTracker Radar at HinghamWeather.com indicated that the rotation in the storm was gone, leaving heavy rain and windy conditions behind. This too, turned out to be the case. |
