March 2018 Nor'easter

Overview

In March 2018, a powerful late-season nor'easter brought heavy snow to the High Country, demonstrating that significant winter weather can occur well into spring in the mountains. The storm dropped over 20 inches of snow at higher elevations, with heavy, wet snow causing widespread tree damage and power outages across the region.

The March timing made this storm particularly impactful. Trees that had begun leafing out were vulnerable to the weight of wet snow. Power lines, already under stress from spring conditions, failed under the snow load. The storm served as a reminder that winter in the High Country doesn't follow the calendar and that March can bring significant snow events.

Key Statistics

Date

March 2018

Peak Snowfall

20+ inches

Storm Type

Nor'easter

Snow Character

Heavy, Wet

Impact and Damage

Heavy, Wet Snow

The March timing and storm characteristics created particularly damaging snow:

High Water Content: Warmer temperatures meant snow had high moisture content
Heavy Weight: Each inch of this snow weighed much more than typical winter snow
Tree Stress: Weight of snow combined with spring conditions caused extensive tree damage
Accumulation on Everything: Wet snow stuck to and accumulated on all surfaces

Tree Damage and Power Outages

Extensive tree damage across the region from heavy snow weight
Trees with early leaf buds particularly vulnerable to damage
Thousands lost power as trees fell on power lines
Power restoration took several days for many areas
Damage to tree canopy visible for months afterward

Travel Disruption

Roads quickly became snow-covered and hazardous
Many residents caught off-guard by late-season snow
School closures throughout the region
Business closures as conditions deteriorated
Spring break travel plans disrupted for many

Higher Elevations Hit Hardest

Areas above 3,500 feet received heaviest snowfall
Beech Mountain, Blowing Rock, Banner Elk areas: 20+ inches
Boone area: 15-20 inches
Lower elevations saw less snow or rain/snow mix

Meteorological Context

Nor'easter Development

The storm was a classic nor'easter that tracked up the coast:

Low pressure system developed off the Carolina coast
System tracked northward along the coastline
Drew Atlantic moisture inland
Cold air in place over mountains allowed for heavy snow
Northeasterly winds gave the storm its name

March Snow Characteristics

Why March snow is different from January snow:

Higher Sun Angle: More solar radiation during day
Warmer Temperatures: Temperatures near or just below freezing
High Moisture Content: Air holds more moisture in March
Wet Snow: Results in heavy, sticky accumulation
Rapid Melting: March snow often melts quickly once storm passes

Spring Storm Pattern

The 2018 storm fit a pattern of significant late-season events:

Mountains often see significant snow into March and even April
Late-season coastal lows can produce major snowfalls
“Spring” winter storms can rival mid-winter events for snow amount
Timing catches people off-guard who have moved on mentally to spring

Why March Snow Matters

Ecological Impact

Early Bloomers: Plants that had begun blooming suffered damage
Wildlife: Birds and animals already in spring patterns faced challenges
Tree Damage: Damaged trees more vulnerable to disease and insects
Spring Activities Delayed: Maple syrup season, early crops affected

Human Impact

Many had already switched to spring tires, summer wardrobes
Snow removal equipment sometimes already put away
Mental adjustment from spring back to winter conditions
Tourism impacts as spring break visitors encountered winter
Reminder that winter gear should remain accessible through March

Infrastructure Stress

Power grid stressed by combination of wet snow and early spring conditions
Road crews had to re-mobilize winter equipment
Salt and sand supplies often running low by March
Budget impacts as winter weather extended into fiscal year end

Historical Context

High Country's March Snow History

Significant March snowstorms are part of High Country history:

March 1993: The legendary “Storm of the Century” struck in mid-March
March 2018: This nor'easter brought 20+ inches
March snow events occur every few years
April snow is not unheard of at higher elevations
Last freeze typically doesn't occur until late April or early May

Climate and Seasonal Transitions

Understanding spring snow in context:

High Country's elevation means extended winter season
Transition from winter to spring often has back-and-forth pattern
Warm spells followed by winter returns are normal
Old timers' saying: “Don't put winter clothes away until Mother's Day”

2018 in Context: A Wet Year

The March 2018 nor'easter was just one event in an exceptionally wet year:

2018 became the wettest year on record for the High Country
Approximately 93 inches of precipitation vs. 59-inch average
Seven major precipitation events during the year
March snow contributed to annual total
Hurricane Florence remnants later in September added more
Pattern of intense precipitation events separated by dry periods

Lessons and Preparedness

Never Too Early to Put Winter Away

The 2018 storm reinforced important lessons:

Keep winter clothing accessible through April in High Country
Don't switch to summer tires too early
Maintain emergency supplies into spring
Be prepared for power outages from spring snow
Have backup heat sources available

Tree and Property Protection

Trim trees near power lines year-round
Remove dead or damaged branches before they fail
Consider tree species that handle wet snow better
Have tree service contacts ready for emergencies
