41 Tornadoes in US and Canada including an F5 in Mercer County Pennsylvania and also multiple F3-F4 Wedge Tornadoes and one tornado in central part of the state that had a width up to 1.5-2.2 Miles Wide. It is possible that there were more F0 and F1 tornadoes that were missed in the survey.
The tornado that struck the Niles are was at F5 intensity at the time; houses were wiped clean off their foundations. Damage in Ohio totaled $60 million. The same tornado also devastated Wheatland, Pennsylvania.
It's rather hard to directly measure a tornado's sheer intensity. There are several variables that would go into that such as forward speed, objects in the way, length of intensity, and width, though only damage and estimated wind speed are used in rating a storm. In addition, those that happened years ago before the Fujita scale was implemented would be that much harder to analyze. It's important to remember the peak intensity varies and the most intense are not intense the entire track. The Fujita scale is also limited in that once F5 damage takes place the sheer degree of damage makes it difficult to determine whether one tornado or another had faster winds. With that said, some of the most intense would include 1925 tri-state tornado; 1999 Oklahoma City; 1997 Jarrell, Texas; 1896 Sherman, Texas; 1947 Woodward, Oklahoma; 1957 Fargo, ND; 1974 Xenia, Ohio; 1974 Guin, Alabama; 1977 Birmingham, Alabama; 2011 Phil Campbell, Alabama; 1985 Wheatland, Pennsylvania; 1955 Udall, Kansas; 1991 Andover, Kansas; 1998 Lawrence county, Tennessee; 1990 Goessel, Kansas; 1953 Flint, Michigan; 1974 Brandenburg, Kentucky The Oklahoma City tornado of 1999 had the fastest measured winds of any tornado. However, direct wind measurements of tornadoes are rare, so other F5 tornadoes that did not have their winds measured may have been stronger. The 1997 Jarrell tornado produced the most intense tornado damage every formally documented as an entire subdivision was completely erased. Everything above the ground wand some of the ground itself was swept away without a trace; only concrete slabs remained. However, some people attribute the extreme damage in part to the tornado's slow movement allowing it to tear away at the same spot for longer than usual. The 1991 Red Rock, Oklahoma, 1995 Kellerville Texas and 1999 Mulhall Oklahoma tornadoes are officially F4's because they did not hit well-built structures. However they are speculated to be some of the most intense F5s like the ones on this list.
The 1985 earthquake caused significant damage to Mexico City, Mexico.
The RM Nimbus series of computers was first introduced in 1985. It was a range of desktop computers developed by Research Machines, a British computer company.
im realy not sure but i think it was 3 Sep 1985
Yes. Tornadoes, some of them devastating, can and do occur in Ontario. Two notable ones are the Windsor F3 tornado of April 3, 1974 Barrie F4 tornado of May 31, 1985.
Palm Beach has been affected by several weak tornadoes. There was an F0 tornado on August 5, 1985, an F1 tornado on November 15, 1994, and an EF0 tornado on August 30, 2013.
Such an event is usually referred to as a tornado outbreak. The outcome depends largely on the severity of the outbreak. Some of the more infamous outbreaks include: The Super Outbreak of 1974, 148 tornadoes (20 in Illinois, 27 in Kentucky, 37 in Tennessee) hit 13 states and 1 Canadian province, killing 319. The Pennsylvania, Ohio, Ontario, Outbreak of 1985, 41 tornadoes (21 in PA) hit parts of Ontario, Ohio, Pennsylvania, and New York, killing 74 in the U.S. Most deaths came from the three worst tornadoes (Niles-Wheatland 18, Cochranton 16, and Albion 12). The Oklahoma-Kansas outbreak of 1999, 74 tornadoes hit parts of Oklahoma and Kansas (59 in Oklahoma), killing 46 people, most of the deaths come from a single F5 tornado (Moore-Bridgecreek 38). The Super Outbreak of 2011 a record 350 tornadoes (30 in Arkansas, 35 in Texas, 41 in Mississippi, 62 in Alabama, 76 in Tennessee) touched down in 4 days in 20 states and one Canadian province killing 324 people. 208 tornadoes touched down on April 27 alone, killing 319. Over 200 deaths resulted from just 5 tornadoes (Hackleburg-Phil Campbell 72, Tuscaloosa-Birmingham 64, Rainsville 25, Smithville 23, Shoal Creek-Ohatchee 22)
Yes, of course, there are tornadoes in Pennsylvania. The most-recent severe outbreak occurred in 1985 when a system of tornadoes developed near Albion in northwest Pennsylvania and tracked across the state. Forty-seven confirmed tornadoes were associated with this outbreak, and there were numerous injuries and deaths before the system weakened in north-central and southeastern PA.
Yes. There have been several tornadoes in the Cleveland Metro area. Most notably it was at the end of the damage path of a deadly and very long-tracked F4 tornado that tore a swath 118 miles long on June 8, 1953.
Some of the largest tornadoes on record in the U.S. are:The Hallam, Nebraska tornado of May 22, 2004. This massive F4 tornado was, at one time, 2.5 miles wide. It is commonly state as the widest tornado on recordThe Mulhall, Oklahoma tornado of May 3, 1999. This F4 tornado is usually overshadowed by the smaller but more intense tornado that struck Oklahoma City on the same day. Doppler Radar indicated that the tornado may have been as much as 4 miles wide, but evidence in the damage path could not confirm this.The Seneca, Kansas tornado of May 17, 1896. The F5 tornado, which devastated several towns in Kansas, was over 2.2 miles wide at one point.The Moshannon State Forest, Pennsylvania of May 31, 1985. This F4 tornado was part of the most intense tornado outbreak to strike the northeastern U.S. It carved a damage path at least 2.2 miles wide through the forests of central Pennsylvania.
Outbreak of Hostilities - 1985 TV is rated/received certificates of: Australia:M
The event you are referring to was not a single tornado but an outbreak that covered portions of Ontario, Ohio, Pennsylvania, and New York. There were 41 tornadoes in all, 28 of which affected Pennsylvania and Ohio. Four of these tornadoes crossed the OH/PA state line. The most significant was the F5 tornado that devastated Newton Falls and Niles in Ohio and Hermitage and Wheatland in Pennsylvania. The outbreak occured when an unsually warm, moist air mass moved over the region. This unstable air mass was primed to produce severe thunderstorms. However, a stable layer of air, called a cap, prevented the storms from developing. Since the energy in the atmosphere could not be released, the air mass continued to become more unstable. Eventually this cap weakened and a cold front moved in, triggering thunderstorms. These storms interacted with wind shear, or shifts in wind speed and direction with altitude, causing them to rotate and turn into supercells, the most powerful type of thunderstorm on Earth. The rotation in these supercells was able to develop into tornadoes, some of which were extremely violent. In this outbreak, 8 tornadoes were rated F4 (2 in Canada, 6 in the U.S.) and 1 was rated F5.
Yes. On May 31, 1985 a series of destructive tornadoes tore across parts of Ontario, Ohio, and Pennsylvania, killing over 80 people including 65 in Pennsylvania, whch suffere the worst damage. Of these tornadoes 8 were rated F4, 6 of which struck Pennsylvania and another which crossed the Ohio/Pennsylvania line was the only F5 tornado in Pennsylvania history. The most significant tornadoes include: The F4 tornado that hit Barrie, Ontario killing 8. The F4 tornado that hit Albion and Cranesville, Pennsylvania killing 12 The F4 tornado that hit Atalntic City and Cochranton, Pennsylvania, killing 16 The F5 tornado that hit Niles, Ohio and Hermitage, Pennsylvania, killing 18 The F4 tornado that hit Moshannon State Forest, Pennsylvania and grew to over 2 miles wide. In terms of Major hurricanes in 1985 there were 3: Elena, Gloria, and Kate. Of these hurricanes Elena and Gloria were bad enough to have their names retired, each causing hundreds of millions of dollars in damage.
Some very large tornadoes that have been recorded includeThe Hallam, Nebraska tornado of May 22, 2004 (the largest ever recorded) at 2.5 miles wide.A tornado north of Greensburg, Kansas on May 4, 2007 at 2.2 miles wide.The Moshannon State Forest, Pennsylvania tornado of May 31, 1985 at 1.9 miles wide.The Yazoo City, Mississippi tornado of April 24, 2010 at 1.75 miles wideThe Greensburg, Kansas tornado of May 4, 2007 at 1.7 miles wide.
Some natural disasters of the 1980s include the eruption of the volcano Mount Saint Helens in 1980, Hurricane Allen in 1980, the United States-Canadian tornado outbreak in 1985, The Edmonton, Alberta tornado in 1987, Hurricane Gilbert in 1988, Hurricane Hugo in 1989, the Daulatpur-Saturia tornado in 1989.
Xghajra Tornadoes F.C. was created in 1985.
