Hurricane Allen

{{Storm path|Allen 1980 path.png|left|colors=new}}

Allen was an early-season Cape Verde-type hurricane, originating from a tropical wave that left the African coastline on July 30. The system developed quickly as it moved westward, becoming a tropical depression the following day. However, the National Hurricane Center did not initiate advisories on Allen until almost 24 hours later, when it was centered {{convert|1300|mi|km|abbr=on}} east of the Windward Islands.{{cite web|url=http://www.nhc.noaa.gov/archive/storm_wallets/cdmp/dvd0103-jpg/1980/atlantic/allen/public/pub08012200z.jpg|title=Tropical Depression Advisory Number 1|author=Gilbert Clark|date=August 1, 1980|publisher=National Hurricane Center|access-date=May 13, 2011}} Early on August 2, as the depression moved quickly westward towards the Caribbean, it intensified into the first named storm of the 1980 Atlantic hurricane season. Allen rapidly strengthened as it continued westward. By the time an aircraft reconnaissance plane entered the tropical cyclone's center late on August 3, it had already achieved major hurricane status, with maximum sustained winds of {{Cvt|125|mph|km/h|round=5|abbr=on}} and a minimum central pressure of {{Cvt|967|mbar|inHg}}, making Allen a Category 3 hurricane. The storm's central pressure dropped to {{Cvt|951|mbar|inHg|abbr=on}} that night as its eye passed north of Barbados on August 4.

Allen continued to move quickly westward and entered the Caribbean Sea shortly after passing south of St. Lucia. Allen's rapid intensification continued during this time, as it was steered by a mid- to upper-level ridge to its north. Shortly before 0000 UTC on August 5, the hurricane's minimum pressure decreased to {{convert|924|mbar|hPa inHg|abbr=on}}, which was noted as equivalent to Hurricane David in the previous season.{{cite web|url=http://www.nhc.noaa.gov/archive/storm_wallets/cdmp/dvd0102-jpg/1980/atlantic/allen/tropdisc/tcd08042100z.jpg|title=Discussion for Hurricane Allen, 5 p.m. EDT, August 4, 1980|author=Miles Lawrence|date=August 4, 1980|publisher=National Hurricane Center|access-date=May 13, 2011}} Another reconnaissance aircraft shortly thereafter discovered Allen had become an extremely strong Category 5 hurricane, with sustained winds of {{Cvt|180|mph|km/h|round=5|abbr=on}} and a minimum pressure of {{Cvt|911|mbar|inHg|abbr=on}} the following day. This was the lowest central pressure ever recorded in the eastern Caribbean Sea.{{cite web|url=https://www.weather.gov/lch/1980Allen|title=Hurricane Allen July 31-August 11, 1980|author=Donovan Landreneau|publisher=National Oceanic and Atmospheric Administration|access-date=November 26, 2024}} Allen maintained its extreme intensity for most of the day. However, late on August 5, the storm began to weaken as it underwent an eyewall replacement cycle and interacted with the mountainous terrain of Hispaniola, with the storm taking a northwestward jog south of the island, a common track deviation for most hurricanes that have passed through the area.{{cite news|url=https://www.weather.gov/media/lch/events/1980Allen/1980Allen-NHC%20Report.pdf|title=1980 Allen-NHC Report|publisher=National Hurricane Center|access-date=November 26, 2024}}

Allen resumed a more westward course as it left behind Hispaniola and passed north of Jamaica and the Cayman Islands on August 6. The very warm waters of the northwestern Caribbean Sea allowed the storm to begin another phase of rapid intensification. Allen reached its second and greatest peak intensity on the afternoon of August 7, with maximum sustained winds of {{Cvt|190|mph|km/h|round=5|abbr=on}} and a minimum barometric pressure of {{Cvt|899|mbar|inHg|abbr=on}}. Allen had the highest maximum sustained winds ever recorded in an Atlantic hurricane. Its minimum pressure of 899 millibars was the second-lowest pressure on record for the basin at the time. The major hurricane was also very large at this time, with hurricane-force winds extending {{Cvt|144|mi|km|abbr=off}} from its center and tropical-storm-force winds extending 345 miles. Allen's circulation filled nearly the entire Gulf of Mexico, and was regarded at the time as the second-largest Atlantic hurricane on record, after 1961's Hurricane Carla. Continuing westward, the southern portion of Allen's circulation passed over the Yucatán Peninsula, causing the cyclone to weaken again. Allen bottomed out with winds of {{Cvt|130|mph|km/h|round=5|abbr=on}} on August 8. Continued movement west over the warm waters of the Gulf of Mexico allowed Allen to restrengthen into a Category 5 hurricane for a third time as it moved over the open waters of the Gulf. The hurricane's central pressure dropped back to a tertiary low of {{convert|909|mbar|hPa inHg|abbr=on}}. Pressure falls over the southern United States at this time indicated Allen would soon slow its forward motion as it approached Texas. Allen's forward speed slowed considerably in the hours before it made landfall near Brownsville as a low-end Category 3 major hurricane on August 10. The storm rapidly weakened as it moved inland, eventually dissipating over the mountainous terrain of northern Mexico the following day.

As Allen approached the Caribbean Sea, gale warnings and a hurricane watch were issued for the islands of Barbados, St. Lucia, St. Vincent, Dominica, Grenada, Martinique, and Guadeloupe during the daylight hours of August 3. Gale warnings were in effect for Antigua from 11 am on August 3 until 11 am on August 4. Hurricane warnings were raised for Barbados, St. Vincent, St. Lucia, Martinique, and Dominica from the early afternoon of August 3 until the late morning of August 4. As Allen moved into the Caribbean sea, hurricane watches were issued for southeastern sections of the Dominican Republic and the southwestern peninsula of Haiti from 11 am on August 4 until the morning of August 5. Gale warnings were then in effect for the southern Dominican Republic from the night of August 4 into the night of August 5, while southern Haiti maintained the warnings from the night of August 4 into the morning of August 5. The hurricane watch was issued for Jamaica during the morning hours of August 5, while hurricane warnings were raised for the southwest peninsula of Haiti from the late morning of August 5 into the morning of August 6.{{cite web|author=National Hurricane Center|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1980-prelim/allen/prelim03.gif|title=Hurricane Allen Tropical Cyclone Report Page 3|publisher=National Oceanic and Atmospheric Administration|year=1980|access-date=February 16, 2010|author-link=National Hurricane Center}} Hurricane warnings went into effect for Jamaica from around noon on August 5 until late in the afternoon of August 6. The Cayman Islands saw hurricane watches issued from the afternoon of August 5 into the morning of August 6 before the watches were upgraded to hurricane warnings from the morning until late afternoon of August 6.

As Allen approached the Gulf of Mexico, hurricane warnings were raised for the northeast Yucatán peninsula of Mexico from the afternoon of August 6 into the morning of August 8. Gale warnings were in effect for the Florida Keys from the evening of August 6 into the early morning of August 8. As Allen approached its final landfall, the northeast Mexican coast and Texas coast were placed under a hurricane watch from the morning of August 8 until the morning of August 9 for Mexico and the afternoon of August 9 for Texas. Hurricane warnings were posted for the Texas coast during the afternoon of August 8, and were lowered north of Freeport, Texas during the afternoon of August 9 and south of Freeport during the afternoon of August 10. Gale warnings and a hurricane watch were issued for the Louisiana coast from Vermilion Bay westward from the afternoon of August 8 into the afternoon of August 9. Hurricane warnings were in effect for northeast Mexico from the early afternoon of August 9 into the late afternoon of August 10. Hurricane warnings were downgraded to gale warnings between High Island, Texas and Freeport, Texas between the late afternoon of August 9 and the late afternoon of August 10. Hurricane watches were dropped for the Louisiana coast during the late afternoon of August 9. Hurricane warnings were downgraded to gale warnings for the lower Texas coast south of Freeport from the late afternoon of August 10 into the early morning of August 11.{{cite web|author=National Hurricane Center|url=http://www.nhc.noaa.gov/archive/storm_wallets/atlantic/atl1980-prelim/allen/prelim04.gif|title=Hurricane Allen Tropical Cyclone Report Page 4|publisher=National Oceanic and Atmospheric Administration|year=1980|access-date=February 16, 2010|author-link=National Hurricane Center}}

In addition to the various watches and warnings put in place ahead of Allen's arrival, various international governments took measures to prepare for the hurricane in Haiti. A disaster committee and executive committee to address the aftermath of the storm was formed by Haitian President Jean-Claude Duvalier, the latter of which was headed by members of the Haitian Ministry of Health and Hatian Red Cross, while members of the committees included representatives from the army, Pan American Health Organization (PAHO), United States Agency for International Development (USAID), and others. Emergency instructions were issued by the Haitian government to prevent possible increases in malaria cases following Allen's passage. The United States government made preparations to send personnel, as well as financial and aerial assistance, to Haiti.{{cite report |url=https://pdf.usaid.gov/pdf_docs/PBAAH099.pdf |archive-url=https://web.archive.org/web/20211002213432/https://pdf.usaid.gov/pdf_docs/PBAAH099.pdf |url-status=dead |archive-date=October 2, 2021 |title=Disaster Case Report:Haiti - Hurricane Allen |date=August 5, 1980 |publisher=Office of Foreign Disaster Assistance |access-date=November 26, 2024}} [https://web.archive.org/web/20211002213432/https://pdf.usaid.gov/pdf_docs/PBAAH099.pdf Archived] from the original on October 2, 2021.

A total of 2,500 troops were put on alert in Texas prior to the storm's passage.{{cite news|title=Texans flee before rampaging Allen|url=https://books.google.com/books?id=OvJcAAAAIBAJ&dq=Hurricane+Allen+evacuation&pg=PA1&article_id=4081,1149204|newspaper=The Morning Record and Journal|date=August 9, 1980|access-date=November 27, 2024}}

Allen caused just over $1 billion (1980 USD) in damages and killed at least 281 people throughout its course (including indirect deaths).

The island of St. Lucia sustained catastrophic damage from Allen when it was a strong category 3 hurricane. Sustained winds of {{convert|90|kn|km/h}} and a sea level pressure as low as {{convert|967|mbar|inHg}} were reported at Hewanorra. A total of $235 million in damage was incurred on the island.{{cite journal|url=http://www.aoml.noaa.gov/general/lib/lib1/nhclib/mwreviews/1980.pdf|publisher=American Meteorological Society|title=Atlantic Hurricane Season of 1980|journal=Monthly Weather Review|author1=Miles B.

One death in Guadeloupe was attributed to Allen.

In Barbados, damages were estimated to be $6 million (1980 USD) by local officials, mostly to agriculture, housing and the local fishing industry. The highest recorded winds on the island were 68 knots ({{Cvt|78|mph|km/h|abbr=on}}) on its south side, though Allen likely brought much stronger winds of greater than 100 knots ({{Cvt|115|mph|km/h|abbr=on}}) on the northern part of Barbados under the eyewall of the hurricane. About 500 houses were either damaged or destroyed. No deaths were reported. 20 small boats were destroyed on the island and another 75 sustained damage. In Martinique, damage was extensive as the storm passed {{convert|50|mi|km}} south of the island. Waves {{convert|6|m|ft}} high battered the coast of the island during the storm.{{cite journal|jstor=4300098|journal=Journal of Coastal Research|volume=15|pages=877–899|title=Trade Wind Intensification and Hurricanes on a Caribbean Beach, Martinique Island: A Comparison of their Morphological Effects From Field Experiments and Numerical Simulations|author1=K.

Citrus and tobacco crops were ruined on Isla de la Juventud. 25,000 exchange students were stuck on the island during Allen's passage. Additional coffee and banana crops across the Caribbean were devastated by the hurricane.

Extensive damage occurred in Haiti due to high winds and flash flooding. Total costs for that country were estimated to be at more than $400 million (1980 USD). 2.5 million people were affected by the storm, with an estimated 333,000 people considered at risk for food shortage. Roughly 60% of the nation's coffee crop was destroyed. In Port-au-Prince, Allen caused many fallen trees, local flooding, and temporary disruptions to electric power and telephone services. The island of Île-à-Vache had its food supply depleted and its entire water supply contaminated with salt water.

The storm caused seven deaths in Texas and 17 in Louisiana, most in the latter state resulting from the crash of a helicopter evacuating workers from an offshore oil platform. Allen spawned several tornadoes in Texas; a total of 29 were reported in association with the hurricane. One tornado caused an estimated $50 million in damage when it hit an airport in Austin, Texas. Two offshore oil rigs in the Gulf of Mexico were destroyed by Allen, and 13 people died in the aforementioned helicopter crash during the evacuation of a rig.

As Allen only affected sparsely populated regions of Mexico, there were no reports of significant damage. The Panamanian freighter Georgios G went missing on August 5 on the way to Belize City with 25 people aboard. While information on the ship's fate is incomplete, it was likely intercepted by Allen on its course.

In the aftermath of Allen, the United States Department of Defense announced it would be providing aid to St. Lucia, Haiti and Jamaica. A C-130 cargo plane delivered humanitarian supplies and radios to St. Lucia. Two helicopters flew to the Haitian capital Port-au-Prince and three reconnaissance aircraft were sent to Jamaica, all for damage surveys. Haitian President Jean-Claude Duvalier declared Haiti's Tiburon Peninsula a disaster area. A network of ham radios was utilized to communicate with isolated victims of the hurricane across the eastern Caribbean.{{cite news|author=Mike Wenland|title=Emergency networks help prove value of radio|url=https://books.google.com/books?id=9uBLAAAAIBAJ&dq=hurricane+allen+aftermath&pg=PA16&article_id=5853,1128338|newspaper=The Free Lance-State|publisher=The Free Lance–Star Publishing Co.|date=September 6, 1980|access-date=December 9, 2024}} The Haitian Red Cross coordinated aid with other regional Red Crosses, needing supplies and food to support 50,000 people affected by Allen.{{rp|p=2}} Seeds were distributed to small farm owners to allow for the quick replant of crops lost in the storm.
