Bronx Storm Was a Tornado, meanwhile in Montana...

The ferocious windstorm that splintered trees and uprooted signs in the Bronx on Sunday afternoon turns out to have been a tornado. On Monday, the National Weather Service declared it an EF-1 tornado, with winds of 100 miles an hour.

Between 2:50 p.m. and 3 p.m. Sunday, the Weather Service said, the twister spun through six-tenths of a mile of northern Riverdale near the Hudson River, carving a path 100 yards wide and injuring seven people. Buildings damaged included the Hebrew Home for the Aged on Palisades Avenue.

The last time a tornado had touched down in the city was in 2007 in Sunset Park and Bay Ridge, Brooklyn. A tornado had last hit the Bronx in 1974.

HELENA, Mont. — A rare tornado tore through a farmhouse and killed two people inside, leaving nothing but the house's foundation and a few twisted vehicles as it swept through Montana's remote and sparsely populated northeastern corner.

A teenage boy and a man in his 40s were killed on the farm when the tornado touched down Monday evening about 13 miles west of Reserve, Sheridan County Sheriff Patrick Ulrickson said. A 71-year-old woman was taken by ambulance to a hospital in Plentywood and will be transported to Billings, he said.

Tornadoes are relatively rare in Montana, although on June 20, a tornado tore apart the state's largest indoor arena. The June tornado touched down on top of the Rimrock Auto Arena in Billings, tearing off the roof and some siding and causing extensive damage to the interior. The arena was not in use at the time.

The tornado was the first large tornado to hit Billings in more than a half-century.
