Read the full account →The remains of tropical storm Hanna moved through eastern New England dumping 3 to 6 inches of rain in New Hampshire in about 8 hours causing rapid rises on area streams. Road washouts were the major problem.
Read the full account →A weak northeasterly flow set up across New England, which coincided with the highest astronomical tides of the year. There was very little wave action with this system which helped mitigate any problems.
