HOPKINGTON, N.H. (AP) — Powerful thunderstorms that swept across northern New England knocked down trees, caused flooding and set a library afire in New Hampshire.

Officials say lighting was to blame for the fire at the Hopkinton Library. The blaze was quickly doused Friday and workers were trying to preserve as many books as possible.

No one was hurt.

In Manchester, New Hampshire, the deluge caused flash flooding, forcing road closures. The water was waist-deep in some areas before receding Friday night.

Taylor Patterson from the National Weather Service said more rain was on tap Saturday. She said there could be more lighting and thunder before the rain subsides by Saturday evening.
