Agawam microburst, Windsor Locks tornado statements

By Meteorologist Mike Skurko

The National Weather Service has reviewed the two significant weather events in the Pioneer Valley today, and concluded that a microburst hit Agawam, while an EF-1 tornado touched down in Windsor Locks, CT.  Maximum wind gusts were estimated at 80 mph for the microburst and 90 mph for the tornado.  [Note: pure wind speed does not categorize a storm as a microburst vs. a tornado.  They are two completely different phenomenon.  Microbursts can have winds equal to, or stronger than, a weak tornado.]

Here is the full, unedited statement from the National Weather Service regarding each event:
