Part of thetornadoes and tornado outbreaks of 1977 | |
A violent severe weather outbreak struck theSoutheast on April 4–5, 1977. A total of 22 tornadoes touched down with the strongest ones occurring inMississippi,Alabama, andGeorgia. The strongest was a catastrophicF5 tornado that struck thenorthern Birmingham, Alabama, suburbs during the afternoon of Monday, April 4. In addition to this tornado, several other tornadoes were reported from the same system in the Midwest,Alabama,Georgia,Mississippi andNorth Carolina. One tornado inFloyd County, Georgia, killed one person, and another fatality was reported east of Birmingham inSt. Clair County. In the end, the entire outbreak directly caused 24 deaths and 158 injuries. The storm system also caused the crash ofSouthern Airways Flight 242, which killed 72 and injured 22.[nb 1]

Prior to 1990, there is a likely undercount of tornadoes, particularly E/F0–1, with reports of weaker tornadoes becoming more common as population increased. A sharp increase in the annual average E/F0–1 count by approximately 200 tornadoes was noted upon the implementation ofNEXRADDoppler weather radar in 1990–1991.[9][nb 5] 1974 marked the first year where significant tornado (E/F2+) counts became homogenous with contemporary values, attributed to the consistent implementation ofFujita scale assessments.[13][nb 3] Numerous discrepancies on the details of tornadoes in this outbreak exist between sources. The total count of tornadoes and ratings differs from various agencies accordingly. The list below documents information from the most contemporary official sources alongside assessments from tornado historianThomas P. Grazulis.

Developing 4 mi (6.4 km) northwest ofBirmingham, nearUS 78, this violent tornado proceeded northeastward through northernJefferson County. Near the point of touchdown,Daniel Payne College suffered extensive damage, forcing it to permanently close due to the extent of the destruction. Rapidly intensifying, it generated F5 damage in the neighborhood of Hayes Highland, particularly along and near a lane and drive each named Smithfield, from which the tornado derived its moniker. In this area, abutting the intersection ofI-65 andUS 31, hundreds of homes were completely destroyed, many of which were completely swept away, despite being well-built. Some of the homes built into hillsides even had their cinder-block basement walls swept away, and at least one home was reportedly annihilated, with even its foundation said to be missing. Many trees in the area were snapped and debarked and vehicles were thrown and destroyed. A pair ofdump-trucks were thrown through the air as well.Ted Fujita followed the tornado andsupercell from an airplane and while surveying damage; he rated the Smithfield tornado F5, but initially considered assigning a rating of F6. (He once rated the1970 Lubbock and1974 Xenia tornadoes as such, but his preliminary estimates were subsequently revised to the official ratings of F5.) TheNCEI incorrectly list the path as extending from west of Birmingham to east-northeast ofTarrant.[48]
The storms that brought the tornadoes on April 4 also brought a large squall line acrossAlabama. This proved disastrous whenSouthern Airways Flight 242 attempted to fly around the storm and instead flew straight into it. Massive amounts of very large hail and very heavy rain battered the plane and destroyed its engines. With no way to keep flying, it attempted a landing on a stretch of highway inNew Hope, Georgia. The road section used for the forced landing, formerly calledGeorgia State Route 92 Spur, is now calledDallas–Acworth Highway (formerlyGeorgia State Route 381). TheDC-9 actually landed successfully, but then crashed into a gas station, grocery store, and other structures and vehicles during the rollout. The plane was destroyed, killing the flight crew, 60 passengers, and nine people on the ground.[49]
The F5 tornado touched down near the end of the path of three other violent tornadoes that struck the Birmingham region in1956,1998, and2011. The 1956 tornado was an F4 that struckMcDonald Chapel and continued throughEdgewater, northern Birmingham,Fultondale, andTarrant before dissipating, killing 25. In 1998, an F5 tornado touched town in a rural area nearTuscaloosa before impacting Rock Creek,Sylvan Springs, Edgewater and McDonald Chapel, killing 32. The 2011 tornado was an EF4 that devastated Tuscaloosa and then struckConcord,Pleasant Grove, McDonald Chapel, northern Birmingham, and Fultondale before lifting, killing 64.[50]
