Tropical Storm Amelia was a weak but catastrophic
Amelia affected the Texas coast for two days which caused several shipping incidents and minor damage in Corpus Christi and South Padre Island. While active, there were no deaths linked to the storm. However, the biggest impact from the storm followed its dissipation, when its remnants contributed to record rainfall totals over the state. The state, already suffering from a previous drought, believed that the rain would help alleviate the conditions. However, the dry ground aided the flooding from the storm. The rainfall caused several rivers and creeks to flood, especially around the Texas Hill Country and northern Texas, leading to severe damage. Following the storm, President Jimmy Carter declared six counties in the state as federal disaster areas, allowing residents to seek aid from the government. Additional aid was brought in from as far away as New York. Overall, Amelia caused 33 fatalities with an estimated $110 million in damages in what then-governor Dolph Briscoe called one of the worst floods in the history of the state.
Meteorological history
A
On July 30, the disturbance turned to the northwest and entered an area of the Gulf with slightly above normal sea surface temperatures and low vertical wind shear, which favored further development.[3][4] At this point, the presentation seen on satellite imagery had indicated that a tropical cyclone was beginning to form in the Gulf. After a reconnaissance aircraft went into the system, the cyclone was upgraded into the first tropical depression of the season that afternoon while 30 miles (48 km) south of Brownsville, Texas. When it formed, it was moving north-northwest at 12 mph (19 km/h), which was thought at the time to inhibit further strengthening due to the depression moving onto land.[5] Several hours later, the depression was upgraded to Tropical Storm Amelia, a decision that one forecaster said was made to be on the safe side.[6] Amelia peaked at 50 mph (80 km/h) in wind speed when it was upgraded, with the system beginning to skirt the Texas coast.[1] At peak intensity, the storm had gale-force winds along a diameter of 150 miles (240 km).[6]
Amelia, which never had a well-defined center, went up the coast during the afternoon and evening of July 30, making landfall in
Preparations
While the storm was over water, small craft advisories were issued by the Coast Guard in addition to cautioning people on vacation in South Padre Island to avoid the beaches.[8] However, as it was a Sunday evening, most of the ships were already coming into port.[7] As Amelia approached the Texas coast, gale warnings were issued for the area from Brownsville to Port O'Connor on July 30.[9] Due to it forming in close proximity to the coast, warnings were issued as soon as the storm was named.[10] As the state had been in the midst of a severe drought the previous six weeks, there was hope that Amelia would relieve the dry conditions.[11] However, the drought conditions would benefit the floods from the storm due to the ground being rendered so dry that it was unable to soak up all the rain from the storm.[12][13]
Impact
Effects from Amelia as a tropical cyclone ranged from 38 miles per hour (61 km/h) winds in Brownsville to gusts of up to 58 miles per hour (93 km/h) in Corpus Christi. Inland Texas fared much worse, though. The continuous flow of tropical moisture during Amelia's dissipation and remnant stage brought heavy flooding for two to three days, putting 25 counties under flash flood warnings.
Gulf of Mexico and the Texas Coast
In coastal areas of Texas, damage was limited to the sinking of several shrimp boats and the beaching of sail boats. One ship — the Mermaid of the Sea — was caught in the middle of the storm.[8] Although it sank, its crew was rescued.[20] A pleasure boat with three occupants and the two-man crew of a beached catamaran were all reported missing, but were later found.[7][20] Three other people on board a fishing vessel were treated for exposure.[7] Rescue ships were hampered by anchored Mexican boats and surfers in a channel near the Coast Guard station.[21] According to the Coast Guard, all nine ships that had been reported missing in the storm were later accounted for.[22] Along with the ships, an oil drilling rig in the Gulf was ripped from its location and ran aground near Matagorda Island by the storm. The 19 crew members of the rig were rescued by helicopter. As the rig had not yet begun drilling, there was no threat from an oil spill.[7]
In Port Isabel, there was some flooding on the southeast part of the town which was alleviated when some of the manhole covers were opened. In addition, a tornado was thought to have touched down, causing minor damage.[23] South Padre Island reported power outages after receiving over 4 inches (100 mm) of rain and the Queen Isabella Causeway was rendered nearly impassable due to rainfall.[24] During its time as a tropical cyclone, there were no deaths linked to Amelia.[20]
Northern Texas
The town of Albany was hit hard when the town drainage system and
North of Albany, the Brazos River also flooded, with the Clear Fork Brazos River becoming 2 miles (3.2 km) wide at one point, despite normally being a dry creek bed.[25] The Brazos overflowing, in addition to the flooding of the nearby Salt Creek, resulted in the west side of Graham — the county seat of Young County where flood victims from Eliasville and South Bend had taken shelter — becoming flooded over to within blocks of the Young County Courthouse. Later, the flood waters were reported to have entered the basement of the courthouse.[29][32] Effects from the flooding in Graham ranged from 150 houses and 40–50 businesses being inundated to the loss of water and electrical utilities. No fatalities were reported, however, due to the water levels rising gradually, leaving time for residents to evacuate.[33][34] The crest of the Brazos flood then headed for the Possum Kingdom Lake with a threat of lowland flooding, resulting in evacuations of riverside towns in Parker and Palo Pinto counties, although a report from Palo Pinto said that no flooding was expected.[35] The flooding was alleviated at the Possum Kingdom Lake, as the lake was already down 6 feet (1.8 m) from normal and some of the floodgates there were opened, taking most of the water from the flood.[36] Elm Creek, near Abilene, also swelled, flooding into the town, but the only reported damage there was street flooding.[37][38] An additional death was reported in the town of Morse.[26]

Aftermath
Following the storm, there was some controversy as to the nature of the storms. A
In Albany, New York, a disk jockey named Bryan Jackson helped organize a relief effort for the Texas town of the same name, with sponsorship from radio station WOKO and a local supermarket chain. After raising six tons of emergency aid and $1,000 from area residents, a C-130 airplane was loaded with the provisions, but the plane was continuously grounded due to calls saying that Albany, Texas was not a disaster area and did not need the relief. After what was described by U.S. Senator Samuel S. Stratton as almost a comedy of errors, the flight was funded by the Defense Department and was able to take off.[48] In addition, a sheriff dispatch in the Texas town mentioned that aid was possibly being sent from several other towns with the same name as well as from other Texas towns like Abilene.[35]
Records
Amelia and its remnants set several records for rainfall and flooding. The Medina River crested at 45 feet (14 m), breaking the record for flood stage reached on the river that was set in 1919 at 43 feet (13 m) as well as breaking the record for water flow, or the rate in which water flows down the river, at 79 billion gallons per day.[37][42] Additionally, the Brazos River had its highest flooding since 1957.[36] Records were also set for flowing on the Guadalupe, which flowed at 149 billion gallons a day, more than twice the previous record and nearly 1500 times its usual rate of 100 million gallons per day.[37] The storm total of 48 inches (120 cm) measured at Medina was the wettest known storm total rainfall amount for both the state of Texas and any tropical cyclone impacting the continental United States until Hurricane Harvey in 2017.[49] A 12-hour total of 26 inches (660 mm) of rain at Abilene was an extreme example of the precipitation.[3]
In addition, with genesis occurring at a longitude of 97.0°W Amelia holds the record for the westernmost formation of a tropical cyclone in the North Atlantic hurricane database, which dates back to 1851.[50]
