🔴 A wind gust of 89 mph & a temperature of -50 combined for a -108 wind chill on Mount Washington

🔴 Power outages were minimal on Friday night and Saturday morning

🔴 Temperature will be much milder Sunday and Monday


If you think it's been cold at your house, it's a tropical paradise compared to Mount Washington.

The Mount Washington Observatory recorded a wind chill of -108 at 3:49 a.m. Saturday morning, with a wind gust out of the northwest of 89 mph setting a new record, according to National Weather Service meteorologist Stephen Baron in Gray, Maine. He said that despite the observation showing a temperature of -47, the temperature actually reached -50.

The lowest wind chill recorded in the Seacoast region was -48 in York and -46 in Plaistow, according to National Weather Service observations.

There was a water main break in Portsmouth Saturday morning at Vaughn Street and Green Street, according to city spokeswoman Stephanie Secord. Impact on service was minimal, as a work around was implemented.

The Portsmouth indoor pool was also closed Saturday due to a pump failure.

Smoke on the Water

Power outages were minimal with only scattered outages reported on the Eversource, Liberty, New Hampshire Electric Co-op, Unitil, and Central Maine Power outage maps.

ISO New England, the corporation that oversees the power grid, said in a statement that the region is well prepared for the brief cold snap.

"Energy supplies are expected to be sufficient to meet the forecasted consumer demand during this weekend's bitter cold," the organization said. It declared a Cold Weather Watch for Saturday, the seventh in the past five years.

"The region’s supplies of fuel oil are at their highest levels of the season. The expected short duration of the cold weather limits the potential for strain on the region’s stored fuel supplies, including liquefied natural gas (LNG)," the group said.

A Wind Chill Warning remained in effect until 1 p.m. Saturday as wind chills will be around -15. High temperatures won't get out of the low teens, with winds 10-15 mph.

The cold also created what looked like steam rising from many bodies of water Saturday morning.

"That's just the very cold air over the relatively warmer water which creates radiational fog better known as sea smoke," Baron said.

Temperatures will rebound back to normal February levels on Sunday, with highs near 40 on Sunday and into the 40s on Monday under sunny skies.
