At town meeting in Hampton Tuesday, residents could take another big step in adapting to rising seas.

Voters will decide whether to require pilings under new structures in certain at-risk coastal areas.

Last weekend's winter storm caused only moderate flooding on New Hampshire's Seacoast. But it provided a window into how rising seas will make flooding more frequent, bringing challenges to the state's coastal communities.

A new report from Columbia University and First Street Foundation finds that sea level rise and associated tidal flooding have already soaked up value from the coastal New England real estate market.

Researchers say homes have forgone $400 million in relative value since 2005. And in New Hampshire, it has cost homeowners $15 million in lost value.

State legislators will consider how to prepare New Hampshire for the effects of climate change this session – including with one bill that would help coastal towns facing rising seas.

Seacoast-area state Senator David Watters spoke at the Seacoast Environmental Film Festival Saturday, after a documentary about sea level rise on the Chesapeake Bay.

This week's new moon and the remnants of tropical storm Chris could bring unusually high tides and minor flooding to parts of Hampton this weekend.

Drivers on roads near Hampton Harbor usually notice when tides reach their flood stage of 11 feet high. Low-lying pavement can become covered in water.

Thursday night's high tide was over 11 feet, and high tides may hit that around midnight and midday through early next week.

National Weather Service meteorologist William Watson says there shouldn't be any serious impacts.

Deb Bourbeau owns a home in Hampton Beach, and each morning, she checks how high the tides will be. Flooding's been an issue for her and her neighbors.

It's one reason she turned out for the New Hampshire Coastal Climate Summit on Wednesday.

The New Hampshire Department of Environmental Services is offering grants to coastal communities looking to better prepare for the effects of climate change.

A total amount of $200,000 is available to towns, state agencies, and private groups.  

Winning projects in the past have included everything from infrastructure projects, to flood plain studies, to educational outreach programs.

5:30 p.m.: The New Hampshire Department of Transportation reports that the number of crashes are down today, thanks in part to drivers staying off the roads where possible. Roger Lamontagne, of DOT District 3, took this photo of a car off the road at the end of the Laconia bypass in Gilford:

There are only scattered outages, as of 5:30 p.m. Eversource had halved its customer outage to just 50.

3 p.m.:  The latest nor'easter is going a lot easier on area utilities than last week's storm. So far.

Update: The nor'easter March storm soaked New Hampshire's seacoast towns, causing serious flooding in Hampton Beach and forcing the closure of several roads in Hampton to Rye along Ocean Boulevard. 

Flooding was its worst with the mid-day high tide. Several roads that were blocked or closed were open Friday afternoon, while public safety officials are keeping on eye on the next high tide - close to midnight.

The coastal flood warning is in effect until 2 p.m. Saturday. A high wind warning is in effect until midnight.

A winter storm forecast to hit New Hampshire on Friday could result in coastal flooding and power outages.

The National Weather Service issued a coastal flood watch for the Seacoast. High water may have difficulty receding around Hampton, as strong easterly winds pick up over the high tide cycle.

There is also a high wind watch for coastal communities. The storm will generate winds of 20-30 mph, with gusts up to 55 mph.

The Weather Service expects the strongest winds to develop Friday morning, with possible power outages from downed trees and branches.
