The Hurricane Ivan tornado outbreak was a three-day tornado outbreak that was associated with the passage of Hurricane Ivan across the Southern United States starting on September 15, 2004, across the Gulf Coast states of Alabama and Florida as well as southern Georgia before ending in the Middle Atlantic Coast on September 18.

Contents

The outbreak killed 7 people and injured dozens of others across several states from Florida to Pennsylvania. The hurricane itself killed at least 90 people from the US to the eastern Caribbean Islands. Overall, it produced 120 tornadoes, surpassing the record of 117 that was previously held by Hurricane Beulah during the 1967 Atlantic hurricane season. [4] Ivan also produced 16 more tornadoes than Hurricane Frances, whose associated tornado outbreak struck many of the same regions about ten days earlier. The tornado outbreak was also the largest in Virginia history. [5]

Track of Hurricane Ivan

On September 13, 2004, as Category 5 hurricane Ivan moved through the Yucatán Channel, [6] the Storm Prediction Center noted the possibility of isolated tornadoes for parts of Louisiana and the Florida Panhandle three days out. [7] Though the storm weakened while approaching the United States, strong low-level wind shear along its northeastern periphery allowed for the development of potentially tornadic supercells. [8] A National Oceanic and Atmospheric Administration Hurricane Hunter aircraft intercepted Ivan during the afternoon and evening of September 15. During the mission, dropwindsondes were deployed off the Gulf Coast to assess the rainband environment. By this time, an intense band of thunderstorms, with embedded supercells, developed about 250 mi (400 km) east of the hurricane's center. A thermodynamic sounding around 1:00 p.m. EST from Tampa Bay, Florida revealed unusually favorable conditions for deep, rotating convection. Ahead of the band, convective available potential energy (CAPE) levels reached 2,500  J/kg and significant helicity. [9] The significant levels of CAPE, accompanied by a dry air intrusion between the rainband and the main convection of Ivan, were the primary cause of the outbreak. A comparison between Ivan and Hurricane Jeanne revealed that both storms encountered similar conditions near landfall; however, CAPE values were lower during Jeanne and the system produced far fewer tornadoes. [10]

In light of the increased tornado threat, the first tornado watch was issued around 1:00 p.m. EST for the Florida Panhandle and southern Alabama. [11] By then, "miniature" supercell thunderstorms began approaching the coastline. Data from Doppler weather radar indicated mesocyclones within several of the cells, though mostly while over water. At the onset of the outbreak, three cells exhibited signature characteristics of supercell thunderstorms: cyclonic updraft and a hook-like appendage. Similar to storms over the Great Plains, a mid-level rear flank downdraft was present; however, this feature did not reach the surface. [9] Less than an hour after the watch was issued, the first tornado of the outbreak touched down in Escambia County, Florida. Over the course of the next 20 hours, the National Weather Service (NWS) office in Tallahassee monitored over 50 mesocyclones that had sufficient vorticity to spawn tornadoes. The high number of potential storms led to the issuance of 130 tornado warnings, of which only 20 later verified. One of the mesocyclones had a "nearly textbook appearance" and produced four tornadoes between 8:15 p.m. and 9:50 p.m. as it traveled nearly 75 miles across the Florida Big Bend. [1] [2] Two of these tornadoes reached F2 intensity and, collectively, they killed four people, injured eight more, and left $5.5 million in damage. By midnight on September 15, 26 tornadoes had touched down across three states. [1]

With the tornado threat gradually moving northward, new tornado watches were issued further north into much of South Carolina. [12] During the first half of September 16, several F0 tornadoes touched down across the Southeast. [1] By the afternoon, downstream subsidence limited thunderstorm activity; however, as the day wore on, sufficient warm, moist air from the Gulf Stream and breaks in cloud cover allowed for CAPE values to rise. [13] Extensive convective banding to the north and east of the storm continued to encounter extreme levels of helicity. Subsequently, numerous rotating thunderstorms developed over the region, especially across Georgia and South Carolina. [14] Throughout the afternoon, 22 tornadoes touched down across the two states, one of which, an F2, killed one person. [1] The majority of the activity took place along a warm front that developed east of Tropical Storm Ivan within the shear maxima. [15]

Following a lull in activity during the overnight hours between September 16 and 17, conditions once more became increasingly favorable for tornadoes across North Carolina and Virginia. Strong shear associated with the weakening tropical cyclone and the destabilization of air ahead of the main rainband and consequently, a tornado watch was issued for portions of both states around 10:00 a.m. [16]

The tornado outbreak began during the early afternoon of September 15, when the first outer rain bands and thunderstorms moved ashore across the southern states. One person was killed in Panama City, Florida when a tornado tore through the city damaging many businesses. The tornado that hit just before 4:00 p.m. was caught on camera as it skirted just outside a local television station that was doing severe weather coverage as tornado warnings were issued in the Panama City media market area. [17] At the same time, another deadly tornado touched down in Bay County, Florida killing 1 when a wood-frame home was lifted and smashed, killing an occupant. [18] Later during the evening many other tornadoes touched down across the Panhandle region of west Florida. An F2 tornado in Calhoun County, Florida tossed mobile homes in the air, killing two occupants in each of 2 mobile homes. [19] At the same time the center of the hurricane was approaching the Florida/southern Alabama state and coastline near Gulf Shores. At least 26 tornadoes were confirmed during the day.

After the cyclone made landfall near Gulf Shores, Alabama, the tornado activity shifted further north into central Alabama and the northern half of Georgia as well as South Carolina. One person was killed in Franklin County, Georgia by an F2 tornado that damaged several businesses and homes. 32 tornadoes were confirmed on that day. [20] As the remnants of Ivan, now a tropical depression moved further inland, increased instability and thunderstorm cells produced a large tornado outbreak from the northern Carolinas to Pennsylvania. Virginia was the hardest hit state during the day as nearly 40 tornadoes affected the state. [21] Several F2s and one F3 touched down, causing significant damage to numerous structures including homes and businesses. Areas roughly to the west and south of Washington, D.C. were the hardest hit areas. Nearly 60 tornadoes were confirmed on that day before the outbreak ceased during the overnight hours of September 18 across Maryland.

<span class="mw-page-title-main">2002 Veterans Day weekend tornado outbreak</span> Severe weather event in the eastern United States

The 2002 Veterans Day weekend tornado outbreak was an unusually severe and expansive severe weather event across portions of the Central and Eastern United States from the evening hours of November 9 into the early morning hours of Veterans Day, November 11, 2002. A series of troughs tracked eastward across the United States, providing strong wind shear, while anomalously warm and unstable air surged northward into the Ohio River Valley. As a result, multiple tornadoes occurred across Arkansas, Tennessee, and Missouri on November 9. A far more widespread and severe event occurred the following day, with three distinct tornado outbreaks focused across areas from Illinois to Pennsylvania; Tennessee and Kentucky; and areas from Mississippi to South Carolina. The most intense tornado of the outbreak was a violent F4 tornado that occurred near Van Wert, Ohio. A total of 76 tornadoes occurred during the 3-day period, collectively resulting in 36 deaths and 303 injuries. As of 2022, the event ranks as the third-largest tornado outbreak on record in November.

<span class="mw-page-title-main">Hurricane Cindy (2005)</span> Category 1 Atlantic hurricane

Hurricane Cindy was a tropical cyclone that made landfall in the U.S. state of Louisiana in July 2005. The third named storm of the 2005 Atlantic hurricane season, Cindy developed from a tropical wave on July 3, off the east coast of Mexico's Yucatán Peninsula. Soon after, it moved over land before emerging into the Gulf of Mexico. Cindy tracked toward the northern Gulf Coast and strengthened to reach maximum sustained winds of 75 mph (120 km/h), making it a Category 1 on the Saffir–Simpson scale. The hurricane struck near Grand Isle, Louisiana, on July 5 at peak intensity, but weakened by the time it made a second landfall along southern Mississippi. Cindy weakened over the southeastern United States and transitioned into an extratropical cyclone as it merged with a cold front on July 7. The remnants of Cindy produced an outbreak of 42 tornadoes across six states. Eventually, the remnants of Cindy moved into Atlantic Canada, dissipating on July 13 over the Gulf of St. Lawrence.

<span class="mw-page-title-main">Tornado outbreak of November 21–23, 1992</span> 1992 natural disaster in the eastern and midwestern US

The Tornado outbreak of November 1992, sometimes referred to as The Widespread Outbreak, was a devastating, three-day outbreak of tornadoes that struck the Eastern and Midwestern United States on November 21–23. This exceptionally long-lived and geographically large outbreak produced 95 tornadoes over a 41-hour period, making it one of the longest-lasting and largest outbreaks ever recorded in the US, and published studies of the outbreak have indicated the possibility of even more tornadoes. There were 26 fatalities, 641 injuries, and over $300 million in damage.

<span class="mw-page-title-main">Hurricane Earl (1998)</span> Category 2 Atlantic hurricane in 1998

Hurricane Earl was an atypical, disorganized, and short-lived Category 2 hurricane that caused moderate damage throughout the Southeast United States. It formed out of a poorly organized tropical disturbance over the southwest Gulf of Mexico late on August 31, 1998. Tracking towards the northeast, the storm quickly intensified into a hurricane on September 2 and made landfall early the next day near Panama City, Florida. Rapidly tracking towards Atlantic Canada, the extratropical remnants of Earl significantly intensified before passing over Newfoundland on September 6. The remnants were absorbed by former Hurricane Danielle two days later.

<span class="mw-page-title-main">Hurricane Katrina tornado outbreak</span> August 2005 tornado outbreak in southeastern United States

Accompanying Hurricane Katrina's catastrophic coastal impacts was a moderate tornado outbreak spawned by the cyclone's outer bands. The event spanned August 26–31, 2005, with 57 tornadoes touching down across 8 states. One person died and numerous communities suffered damage of varying degrees from central Mississippi to Pennsylvania, with Georgia sustaining record monetary damage for the month of August. Due to extreme devastation in coastal areas of Louisiana and Mississippi, multiple tornadoes may have been overlooked—overshadowed by the effects of storm surge and large-scale wind—and thus the full extent of the hurricane's tornado outbreak is uncertain. Furthermore, an indeterminate number of waterspouts likely formed throughout the life cycle of Hurricane Katrina.

<span class="mw-page-title-main">Tornado outbreak sequence of March 9–13, 2006</span> Weather event sequence

The Tornado outbreak sequence of March 9–13, 2006 was an early season and long lasting tornado outbreak sequence in the central United States that started on the morning of March 9 and continued for over four days until the evening of March 13. The outbreak produced 99 confirmed tornadoes, which killed a total of 10 people. The Storm Prediction Center (SPC) issued multiple elevated outlook throughout the sequence, including a rare high risk for March 12, which would end up being the most intense day of the outbreak, producing 62 in total. 11 F3 tornadoes were tallied, and a violent F4 tornado touched down in Monroe County, Missouri, becoming the strongest of the outbreak. Multiple tornado emergencies were issued for tornadoes throughout the outbreak as well. An intense F3 tornado that affected the towns of Renick and Maddison in Missouri killed 4 people and injured dozens others, becoming the deadliest of the sequence. Multiple of the tornadoes were long-tracked in nature, with 6 of them having paths exceeding 30 miles (48 km). One particular supercell thunderstorm during the outbreak persisted for many hours and progressed in excess of 800 miles (1,300 km) through Oklahoma, Kansas, Missouri, Illinois, Indiana, and extreme southern Michigan.

<span class="mw-page-title-main">Tropical Storm Bill (2003)</span> Atlantic tropical cyclone

Tropical Storm Bill was a tropical storm that affected the Gulf Coast of the United States in the summer of 2003. The second storm of the 2003 Atlantic hurricane season, Bill developed from a tropical wave on June 29 to the north of the Yucatán Peninsula. It slowly organized as it moved northward, and reached a peak of 60 miles per hour (97 km/h) shortly before making landfall in south-central Louisiana. Bill quickly weakened over land, and as it accelerated to the northeast, moisture from the storm, combined with cold air from an approaching cold front, produced an outbreak of 34 tornadoes. Bill became extratropical on July 2, and was absorbed by the cold front later that day.

<span class="mw-page-title-main">Effects of Hurricane Georges in Florida</span>

The effects of Hurricane Georges in Florida lasted for more than a week in late September and early October in 1998. After developing from a tropical wave to the south of Cape Verde on September 15, Georges moved steadily west-northwestward and peaked as a strong Category 4 hurricane on the Saffir–Simpson scale on September 20. After weakening slightly to a Category 3, the cyclone proceeded to strike Antigua, Saint Kitts and Nevis, Puerto Rico, Dominican Republic, and Cuba. Georges emerged into the Straits of Florida as a Category 1, but re-strengthened slightly to a Category 2 before making landfall in Key West, Florida, on September 25. The hurricane continued northwestward into the Gulf of Mexico and struck near Biloxi, Mississippi, on September 28. After moving inland, Georges turned eastward and crossing into the Florida Panhandle on the next day. By October 1, the system dissipated near the northeast Florida–southeast Georgia coast.

<span class="mw-page-title-main">Hurricane Georges tornado outbreak</span>

The 1998 Hurricane Georges tornado outbreak was a six-day tornado outbreak associated with the passage of Hurricane Georges in the Southeast United States. Most of the tornadoes produced by the storm formed in the outer bands of the storm and were relatively weak; however, one F2 tornado touched down in Florida. The outbreak produced 47 tornadoes—20 in Alabama, 17 in Florida and 10 in Georgia—and was the most extensive tornado event in Florida history, with touchdowns reported the entire length of the state.

The effects of Hurricane Jeanne in the Mid-Atlantic region of the United States included two fatalities and $530 million in damage. Originating from a tropical wave off the coast of Africa in early September 2004, Hurricane Jeanne tracked through the Leeward Islands and Hispaniola for several days, resulting in extensive damage and an immense loss of life. After completing a clockwise loop between September 22 and 24, the storm intensified into a major hurricane before striking the Bahamas and Florida. Substantially weaker, the system turned northeastward over Georgia before affecting Delaware, District of Columbia, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia; all of those states are in the Mid-Atlantic region of the United States. By the evening of September 26, the Hydrometeorological Prediction Center took over responsibility of monitoring the former hurricane over Virginia.

This was the first of only two known violent tornadoes ever spawned by a hurricane with the other one happening during Hurricane Hilda in 1964. By the time it was over, the outbreak had killed 14 people, injured 337 others, and caused over $3.461 million in damage.
