In his new book, The Weather Machine, Andrew Blum explores the people, the technology, and the infrastructure behind the weather forecast we rely on day to day, and the role of meteorology in the study of our planet and global policy and decision making. The book is on sale June 25th.

The New Hampshire Electric Cooperative will get $2.8 million in disaster funds to cover damage to its infrastructure from the Halloween storm of 2017.

The Federal Emergency Management Agency says the grant will cover more than three-quarters of the Co-op's repair costs. FEMA says it's given New Hampshire more than $7.2 million dollars total under a federal disaster declaration for the storm which caused widespread flooding, infrastructure damage and power outages at the end of October 2017.

The National Weather Service says strong winds will likely blow down large tree limbs and power lines in parts of northern New England.

The weather service has issued a strong wind warning for southern New Hampshire until this evening. It says wind gusts of 60 miles per hour are likely.

Officials say widespread power outages are possible, and travel could be difficult. Eversource, the state's largest utility, reported almost 4,000 customers without power as of mid-morning.

ISO-New England

New England’s electric grid operators are preparing for the region’s next nor’easter – whenever it arrives – with a special storm training completed earlier this month.

The control room operators at the nonprofit grid manager, ISO-New England, coordinate electric supply with demand, across all six states, around the clock.

“Visualizing it like a NASA control room … if you have that picture in your head, you’re on the right track,” says Stephen George, ISO’s general manager of operational performance and training.

A deluge from the remnants of Hurricane Florence has flooded parts of New Hampshire, forcing firefighters to rescue several people.

In Derry, Fire Chief Chief Mike Gagnon said seven people were rescued by boat Tuesday after water rose 5 to 6 feet outside several small businesses in an industrial area. He said eight others were assisted to higher ground, and about 15 cars were flooded.

The Federal Emergency Management Agency says it's given New Hampshire more than a million dollars in disaster aid after the severe storm that hit nearly a year ago.

The storm in late October 2017 brought heavy flooding and high winds throughout the state.

It washed out major roads, caused widespread power outages, prompted evacuations and destroyed some homes.

MONDAY Night update: The forecast calls for high wind gusts and drifting snow Monday evening, with a cold front sweeping over New Hampshire for the coming days.

We discuss the top stories in science, technology, the environment and energy in New Hampshire in the past year.  From the eclipse that captivated the nation's attention to the biofabrication industry gaining steam in the Manchester Millyard, we look at top stories nationally and in New Hampshire, including extreme weather, solar power, and a bitcoin bubble.  Plus intriguing discoveries in outer space and in the human body.


Update, 2:30 p.m. - A small number of power outages have resulted from the storm. Eversource reports about 266 customers without electricity, as of 2 p.m. 

1  p.m. -- Snow continues to fall in much of the state, though the storm has turned to sleet and rain in the south-eastern part of New Hampshire. The weather  has resulted in numerous school closings and delays - as well as accidents.

In light of the recent hurricanes slamming the Gulf Coast and Southeastern United States, The Exchange spoke with Perry Plummer, Director of Homeland Security and Emergency Management, Jonathan Winter, a Dartmouth professor who has studied increasing precipitation over the last two decades in New England, and two engineers, Jim Gallagher, who specializes in dams, and Fred McNeill, who works in wastewater treatment, about how well New Hampshire is prepared for major weather events.

Hurricane Harvey slammed the Gulf Coast last week, and it got us thinking: How ready is New Hampshire for major storms, hurricanes, and floods?

Perry Plummer, Director of the Division of Homeland Security and Emergency Management for the New Hampshire Department of Safety, says the state has plenty of work to do to ensure our infrastructure can handle the kind of extreme weather events that are becoming increasingly common.

"We know more water is coming; we’re going to get these types of rain storms," Plummer said on The Exchange. "Obviously, I don’t think we’ll get a Harvey in New Hampshire, but we are going to get 10 and 15 inches of rain, and that’s going to challenge our infrastructure. We need to rebuild our infrastructure to protect our residents, protect our critical infrastructure."

Last weekend’s rainstorm did more damage than officials initially assessed. On Thursday evening, twenty local roads remained closed. 

By Wednesday, cities and towns in Grafton County had upped their flood damage tally from $4 million to nearly $12 million. Two state roads, 116 South in Easton and 25A in Orford, will likely remain closed through the coming weekend, although local traffic can access residences in the interim.

On Thursday, Federal Emergency Management Agency officials began a tour of storm damage in the state.

Over the past century, heavy rainfall and snowstorms have grown more frequent and more severe in many parts of the U.S.—including the northeast—as a result of our warming climate. In a study published last month, researchers from Dartmouth College, University of Vermont, and Columbia University investigated exactly what those changes looked like here in New England.

A major snowstorm is brewing just in time for April Fools' Day in parts of New England.

The National Weather Service says the coastal storm is going to bring heavy, wet snow to Maine and New Hampshire starting Friday and continuing through Saturday afternoon.

Meteorologist Tom Hawley says the "jackpot" is going to be 12 to 18 inches of snow in higher terrain between Nashua and Keene in New Hampshire. He says interior sections of southernmost Maine can expect 6 to 10 inches while lesser amounts are forecast farther north.

Northern New England is preparing for another round of wind. And it's going to be much colder this time.

The National Weather Service says 30 mph gusts projected for Saturday in Maine and New Hampshire won't be as strong as the 50 mph-plus gusts recorded Thursday.

But the wind will be accompanied by plummeting temperatures.

The National Weather Service says a Nor'Easter is set to hit New England tomorrow, including much of New Hampshire. It comes off a storm that brought snow, sleet, and ice to most of the state.

Meteorologist Justin Arnott says a good way to prepare for this storm is to clean up from yesterday's.

A winter weather advisory is in effect until midday today as the first nor'easter of 2017 continues to have an impact across the state, with nearly 700 schools and organizations closed for the day.

A new book by Stephen Long describes how this giant storm transformed the New England landscape and seared itself into the memory of its people.  We’ll delve into just how big it was, the wide-ranging impacts, including how the hurricane created public works projects and developed new thinking around forestry. We'll also talk about preparation for the next inevitable great storm.

Update Sunday 7/24 11:30pm: New Hampshire electric utilities say they've restored power to nearly all of the homes and businesses who lost electricity during Saturday's storm.

It's really hot in most of the mainland United States right now. The National Weather Service predicts temperatures in the triple digits through the weekend in much of the South, Midwest and along the East Coast.

The culprit: a "heat dome."

It's a real meteorological event — the National Oceanic and Atmospheric Administration even took the time to define it in the agency's warning this week:

Nearly all of northern New England is under a winter weather advisory this morning, with snow and ice making for difficult driving in many areas.

The Department of Transportation saw car accidents across the state this morning, but officials said incidents were clearing up as rush hour passed.

“With the morning commute being done, that’s helpful,” transportation manager Sue Page said around 9:40 a.m.
