An EF1 tornado with 100 mph winds touched down by the West Regional Library in west Cary on Sunday, Oct. 11, the weather service says. It snapped trees but caused no structural damage.

A tornado touched down in west Cary on Sunday, Oct. 11, the National Weather Service has confirmed. Surveyors rated it EF1, with peak winds estimated at 100 mph.

It formed near the West Regional Library on Morrisville Parkway at 12:29 p.m. and lifted a minute later. It traveled about a third of a mile northeast. No one was hurt.

The National Weather Service in Raleigh published its damage survey at 3:16 p.m. Tuesday. It is the only tornado the weather service has confirmed in Cary from Sunday’s storms.

What the survey found

The survey’s key figures:

  • Rating: EF1, the second-lowest on the Enhanced Fujita scale, which covers winds of 86 to 110 mph
  • Peak wind: about 100 mph
  • Path: 0.37 miles long and up to 50 yards wide
  • Time: 12:29 to 12:30 p.m.
  • Injuries and deaths: none

A large tree was snapped in the library parking lot. Surveyors also found tree limbs 1 to 3 inches thick snapped and scattered through the neighborhood north of the library.

They found no damage to buildings. The weather service said that suggests “the strongest winds remained just above ground affecting mainly treetops.”

The survey’s damage points are mapped in the weather service’s Damage Assessment Toolkit. One note there says the library tree, about 14 inches across, snapped about 10 feet off the ground. Surveyors judged it was at least partly rotted, so they rated that spot at a slightly lower wind speed.

The weather service calls the findings preliminary. They can change before the event is published in its Storm Data record.

What this changes from our first report

On Monday we reported a member of the public’s tornado report about a mile east of Carpenter at 12:32 p.m. The survey confirms a tornado in that spot.

A second public report, about 4 miles southwest of Carpenter, has no survey of its own. The weather service has not confirmed a tornado there.

The other tornadoes Sunday

The Raleigh office surveyed nine tornadoes from Sunday’s storms by Tuesday night. The nearest to Cary crossed the southeast corner of Jordan Lake in Chatham County, about 12 miles southwest, at 12:02 p.m. Surveyors rated it EF1 with winds of 107 mph.

The Perry Creek tornado was the only other one in Wake County. It started about 3 miles north of New Hope, northeast of Raleigh.

Carpenter, Cary Wake EF1 100 mph 0.37 miles
