New Hampshire authorities say initial damage assessments from last weekend's storms and flooding are in excess of $11.5 million.
Perry Plummer, state Homeland security and Emergency Management commissioner, says the vast majority of the damage has happened in Grafton County.
Officials with the Federal Emergency Management Agency started looking at the damage on Thursday.
Plummer said he fully expects to meet the thresholds and justifications required to ask Gov. Chris Sununu to request a presidential disaster declaration.
He said the preliminary damage assessments should be completed in about a week.
The storms dropped more than an inch of rain per hour last Saturday. About 60 roads were damaged, about a dozen homes were surrounded by water and about 600 people were evacuated from campgrounds. No deaths or significant injuries were reported.
