DURHAM, N.H. -- The rainstorm that has affected southern and central New Hampshire since Friday continues to break state rainfall records, according to New Hampshire State Climatologist David Brown at the University of New Hampshire.

Towns on the New Hampshire Seacoast have received nearly a foot of rain since May 12, and more than a foot since May 1. Just half way through the month, Manchester already has broke its all-time monthly record of 10.21 inches of rain set in June 1998, and Portsmouth is close to its all-time monthly record of 15.82 inches of rain set in October 1996.
