Tropical Storm Arlene (1959)
Tropical Storm Arlene was a short-lived tropical cyclone that developed in 1959 a few days before the start of the Atlantic hurricane season on May 30 and arrived in the central coast of Louisiana on land, where one person was killed indirectly. The development of Arlene was slow before the system was able to gain enough convection to be classified on May 28 as Tropical Storm Arlene. The storm intensified slowly and reached its greatest strength on 30 May with peak wind speeds of 95 km / h In the vicinity of the land, the storm weakened rapidly, and during the night the storm came with wind speeds of 75 km / h over the country. Arlene weakened the next morning by today's criteria to a tropical depression off. The system fell apart on the afternoon of May 31 to a remnant low and dissipated late on June 2 over South Carolina.
Arlene invited to the southeast of the United States locally up to 300 mm of rainfall from, with the highest value of 333.5 mm in Houma is accumulated within three days. The heavy rainfall will lead to minor flooding in Louisiana and the damage to property amounted to 500,000 U.S. dollars (in prices of 1959). A dead man was indirectly attributed to the storm, as a man in the stormy sea drowned off the coast of Texas.
Storm History
Tropical Storm Arlene developed from a tropical wave that was first observed on May 23 in the vicinity of the Dominican Republic. This wave developed slowly as she moved through the Caribbean Sea westward. It developed on 25 May to a low pressure area, which two days later arrived in the Gulf of Mexico and a weather observation by a ship the next day revealed that the system had developed a closed circulation. Early the following day, it was found that the system has become the first tropical storm of the Atlantic hurricane season in 1959, the name Arlene was assigned as the center about 480 km south- southeast of New Orleans, Louisiana was and the ongoing winds reached a speed of 65 km / hr. Arlene moved with a forward speed of 15 25 km / h after the northwest and intensified it during the day slowly. On May 29, Arlene turned more to the west, and the forward speed decreased. In the course of the night Arlene was almost stationary. The storm was located about 240 km south of Lafayette, as it northward triftete and the climax of the storm with wind speeds of 85 km / h was estimated. In the post-analysis, it was found, however, that the time of greatest strength of Arlene shortly before reaching the mainland lay with wind speeds of around 95 km / h. When Arlene approached the coast, the storm began to weaken due to the action of the country. Arlene crossed the coastline about 65 km southeast of Lafayette, Louisiana at 16:00 clock cSt wind speeds of 75 km / h as the follow-up analysis revealed surgically this speed was assumed to be 85 km / h. Arlene weakened over land rapidly, by today's criteria to a tropical depression and dissipated on 31 May to a remnant low on. The remnant low was still hanging until June 2, over the southern United States until it finally broke up over South Carolina.
Preparations and impact
The low, which eventually Arlene was introduced on May 27 to wind warnings and recommendations for small vessels for both coasts in southern Florida. When the depth was upgraded the next day to tropical storm warnings for small vessels were spatially expanded significantly. Now included the section from Sabine Pass, Texas to St. Marks, Florida. Storm warnings covered the section between Morgan City, Louisiana, and Pascagoula, Mississippi. For this section, a storm surge was expected, which should reach 0.6-1.2 m above the normal level. When Arlene approached the coast, the warnings for small vessels south of Pensacola been lifted, but extended westward to Galveston, Texas. The warning of a tropical storm now included the stretch of coastline from Galveston up to Grand Isle, Louisiana.
The winds of Arlene reached to 95 km / h with gusts up to 120 km / h The lowest air pressure on land was equivalent to 29.52 inHg, which is about 1000 mbar (hPa ). The storm surge reached up to 90 cm Weeks Iceland and at Point Au Fer, Louisiana. Within the state of local intensity rainfall were recorded, whose maximum value was recorded at 333.5 mm in Houma. The remnant low brought rains to the south of Georgia. In some damages were reported by their banks passing rivers and at the harvest, which were generally low but. Overall, Arlene caused damages in the amount of U.S. $ 500,000 (1959). A person lost indirectly by Arlene their lives - the man drowned off the coast of Galveston in the rough sea.
Names and Weather Records
Due to the minimal impact of the name has not been deleted and re-used, namely 1963, 1967, 1971, 1981, 1987, 1993, 1999 and 2005. He is on the list of the names of tropical cyclones in 2011 and is with nine existing uses of the most commonly used name for a tropical cyclone in the Atlantic Basin since 1950, the naming has begun. By May 30, Arlene marked 1959 until today earliest date on which arrived since the beginning of systematic weather records a tropical cyclone in the state over land.
