Philadelphia Mississippi tornado
During the afternoon hours of April 27, 2011, an extremely powerful and fast-moving EF5 multi-vortex tornado, known commonly as the Philadelphia, Mississippi tornado or the Philadelphia EF5, touched down in eastern Mississippi causing catastrophic damage to the northern outskirts of the town of Philadelphia. Part of the historic 2011 Super Outbreak, the largest tornado outbreak on record, this was the first of four EF5 tornadoes to touch down that day and the first such storm in Mississippi since the 1966 Candlestick Park tornado. While on the ground for 30 minutes, it traveled along a 28.28-mile (45.51 km) path through four counties, leaving behind three deaths, eight injuries, and $1.1 million in damage.
What was the Philadelphia tornado?
The Philadelphia tornado struck eastern Mississippi on the afternoon of April 27, 2011. This fast-moving, multi-vortex EF5 tornado produced catastrophic damage on the northern outskirts of Philadelphia. It formed as part of the 2011 Super Outbreak, which remains the largest tornado outbreak on record. This storm holds historical significance as the first EF5 tornado to touch down in Mississippi since the 1966 Candlestick Park event.
What was the Philadelphia tornado wind speed?
Meteorologists estimated the maximum wind speed within the Philadelphia tornado at 205 mph. This intensity classification of EF5 relies on the extensive damage patterns observed by survey teams. The vortex generated extreme ground scouring, lifting up to 1.6 feet of soil in some locations. Suction vortices embedded within the storm also uprooted and debarked large trees throughout its path.
What was the Philadelphia tornado path?
The tornado touched down at 2:30 p.m. CDT just east of the Philadelphia Municipal Airport in Neshoba County. It traveled a 28.28-mile path in a northeasterly direction through four Mississippi counties. The storm crossed into Kemper and Winston counties before finally dissipating at 3:00 p.m. CDT. This dissipation point occurred approximately 6 miles north of Mashulaville.
How many people died in the Philadelphia tornado?

What caused the Philadelphia tornado?
A powerful supercell thunderstorm spawned this tornado south of Jackson, Mississippi, around 1:00 p.m. CDT. Intense environmental conditions fueled the storm, including CAPE values reaching 3,000 J/kg and dewpoints between 66 and 72 degrees Fahrenheit. A strong southwesterly surface jet intersected a deep, negatively tilted trough, producing extreme wind shear. Storm-relative helicity values exceeded 500 m2s-2, creating a high potential for violent rotating updrafts.
What happened after the Philadelphia tornado?
Governor Haley Barbour declared a state of emergency for 39 Mississippi counties following the outbreak. President Barack Obama subsequently signed a major disaster declaration, allowing access to federal funding for storm victims. Organizations like the Longino Baptist Church and the Salvation Army provided immediate relief and debris removal services. Federal funding totaling over $15.7 million reached victims through the Federal Emergency Management Agency by July 2011.
