EF0 tornado, New Windsor, Maryland, March 16, 2026

This EF0 tornado ran 1.6 miles across Carroll County on March 16, 2026, touching down at 12:02 PM EDT and reaching 150 yards wide. It killed nobody.

Preliminary. This is NWS LWX's damage survey, filed in the Damage Assessment Toolkit as New Windsor. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

Survey Summary:

A line embedded supercell developed and tracked over north-central

Maryland during the late morning into early afternoon hours on

Monday, March 16, 2026. This storm was part of a much larger system

that brought multiple rounds of severe weather to much of the

eastern United States.

Rotation was evident within the storm around 2000 to 3000 feet above

ground on the KLWX WSR-88D radar, prompting a Tornado Warning as the

storm moved from Frederick into Carroll County. The FAA TDWR TBWI

showed this rotation quickly strengthen and lower to below 2000 feet

just to the southeast of the mid-level mesocyclone being sampled by

the KLWX WSR-88D. The tightened lower-level rotation persisted on

TBWI for 1 to 2 minutes after the mid-level rotation on KLWX had

notably weakened.

It was beneath the tightening low-level rotation at around 12:02 PM

EDT that the first evidence of tornadic damage was found. Several

trees in a weakened state just southeast of the intersection of

Hawks Hill Road and Beth Way snapped near the trunk, and fell toward

the east, west, and north. The parent storm motion was northeast.

The trees that fell were only around 100 feet apart at most, with an

undisturbed landscape around it indicating an initially very narrow

vortex perhaps no larger than about 25 to 50 yards in width.

The tornado then crossed through open fields, lifting the south end

of a long irrigation system and rolling it about 100 feet toward the

north just east of Winters Church Road.

After this, the circulation continued northeastward crossing several

more fields and groves of trees, as well as Little Pipe Creek. The

next visible and accessible damage was noted as the tornado

approached and crossed MD-75 Green Valley Road near the intersection

with MD-84 Union Bridge Road. Here, a couple dozen trees fell in

opposing directions (southeast, northeast, east, northwest, and

north). One large tree toppled onto power lines taking down a power

pole and briefly trapping a motorist between the downed wires, pole,

and downed trees. Several large pine trees at the intersection had

their tops sheared off, falling toward the north, northeast, and

east. Two trees on a hill just east of Mill Dale Lane fell toward

the north-northwest, likely just outside the circulation but in its

inflow as it passed across MD-84 Union Bridge Road. Meanwhile, an

outbuilding just to the southwest of MD-75 Green Valley Road

suffered a near total roof collapse, with the west-northwest facing

walls partially collapsed inward. Similar to the trees off Mill Dale

Lane, this outbuilding may have been just outside the tornadic

circulation, with the damage a result of inflow winds into the

vortex as it passed. It is at this point where the tornado reached

its largest and strongest, with an estimated path width of 150 yards

and peak winds of 80 mph. Despite the extent of the damage, only

about one-third of the trees in its path at this point sustained

visible damage, with no other visible damage to other outbuildings

or the farmhouse at the nearby farm.

A video taken from the Carroll County Emergency Operations Center

showed a swiftly rotating lowering, likely the tornado in progress

as it approached and crossed the intersection of MD-75 Green Valley

Road and MD-84 Union Bridge Road, just northwest of their facility.

Although trees in the foreground obstructed the view and could not

confirm ground contact, the video was directly coincident with radar

and the observed (convergent) damage.

A few trees had their tops snapped off just northeast of MD-84 Union

Bridge Road, but no visible damage was noted beyond this point. It

is possible, based on the rotation signature on TBWI, that the

tornado could have persisted for up to another mile over open

fields, but the path length in this survey can only confidently

conclude a path up to this point, approximately 1.68 miles in length.

media, and public that sent in reports of damage.

The damage survey

4 damage points were recorded along this path by NWS LWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

  • Multiple large pine trees blown over. Largest ones fell toward the north-northeast, but several we’re down toward the east. More notably, smaller non-pine trees were uprooted laying towards each other on either side of the road, and across an adjacent field, laying both toward the south and toward the west.
  • Large outbuilding suffered near total roof collapse with west-northwest facing walls partially collapsed inward.
  • Large sprinkler twisted and tossed north.
  • A few weakened trees snapped, falling toward the east, west, and north.

What the Weather Service recorded

A powerful early season cold front spawned multiple rounds of severe thunderstorms. The first round occurred from late morning through mid afternoon, and focused mainly across northern Virginia into north-central Maryland producing scattered wind damage and a brief tornado. As the front itself crossed the region during the evening, a line of low-topped convection aided in the mixing down of an intense low-level jet, resulting in widespread 60 to 70 mph wind gusts near and east of the Blue Ridge and Catoctin Mountains.

The forecast that day

The Storm Prediction Center had this point in a Moderate Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 12:32 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
