Tropical Storm Henri made landfall in southwest Rhode Island around noon on August 22nd, then moved slowly northwestward and westward across northern Connecticut and weakened. Henri brought strong wind gusts and flash flooding. The strongest gusts -- to 70 mph -- occurred along the Rhode Island coast. The worst flash flooding occurred in northeast Connecticut.
As the remnants of Henri moved eastward across southern New England on August 23rd, it spawned three tornadoes and a waterspout in MA and also it caused some renewed flooding.
The highest rainfall totals over the two-day period ranged from 5 to 6 inches in Hartford and Tolland Counties in northern Connecticut and in Franklin, Hampshire, and Hampden Counties in western Massachusetts.

In Bolton, a small, brief tornado touched down, causing minor damage between roughly 175 and 198 Main Street.  One tree was knocked down onto wires and a large branch was ripped from another tree.  It is believed that a funnel cloud initially formed a short distance to the southeast of where the damage was observed, and as it moved northwest, it briefly touched down.  Radar data indicated rotation associated with a shower that moved over the area to be very similar to what was observed with the Marlborough tornado a short while earlier.
