[2][3][4] A tourist group see a waterspout that forms in the ocean off the coast of Plymouth Rock, then it quickly disappears.
Ben, a lighthouse keeper on Little Brewster Island, phones Joe telling him about the tornados he is seeing forming in the sea off the coast which is drawing up and dropping stones.
People run from the harbor, as Joe and Lee search the area to find his children.
Lee predicts that there will be a lot more tornados forming due to recent volcanic eruptions in the area.
The Field Operating Agency (FOA) see this announcement and want to organize a widespread evacuation of the coastal areas.
Ben tells the ship to change its course, but as he is doing this a flying stone hits his lighthouse which collapses on top of him.
Joe, Maddy and Lee go to pick them up, taking backstreet roads to avoid traffic.
Another tornado forms, which Joe decides to launch the bomb into so that it is sucked up into the upper atmosphere.
