Hurricane Beta was a compact, but intense tropical cyclone that impacted the southwestern Caribbean in late October 2005. Beta was the twenty-fourth tropical or subtropical storm, fourteenth hurricane, and seventh and final major hurricane of the record-breaking 2005 Atlantic hurricane season. On October 21, a developing tropical wave entered the eastern Caribbean Sea and spawned Tropical Storm Alpha the following day. As the wave entered the southwestern Caribbean, convection redeveloped and on October 26, the system spawned another low-pressure area which developed into Tropical Depression Twenty-six. The depression intensified into a tropical storm the next morning and was named Beta. By the morning of October 28, the storm intensified into a hurricane, the fourteenth of the season. Beta underwent rapid intensification for several hours to attain its peak intensity with winds of 115 mph (185 km/h) on October 30. The storm began to deteriorate before landfall, weakening to Category 2 status as it crossed the Nicaraguan coastline. Rapid weakening followed landfall, and the storm dissipated early the next morning.
Due to the storm's proximity to Central America, several countries were placed on alert and began allocating supplies for a potential disaster. Several hurricane watches and warnings were raised for the small Colombian island of Providencia as well as the Nicaragua and Honduras coastlines. An estimated 150,000 people were evacuated from dangerous regions in Nicaragua and more than 125,000 more were evacuated in Honduras.
As a tropical storm, Beta produced heavy rains over northern Panama, amounting up to 3 inches (76 mm), which caused several mudslides as well as three fatalities. On October 29, the storm passed over Providencia Island, caused significant damage to structures, and injured 30 people. In Honduras and Nicaragua, over 1,000 structures were damaged by the storm, hundreds of which were destroyed. Ten people were initially feared dead after their boat went adrift during the storm. However, a Panamanian vessel rescued the men after drifting in the water for several hours. Rains in Honduras totaled to 21.82 in (554 mm) and 6.39 in (162 mm) in Nicaragua. Six people were killed in Nicaragua as a result of the storm and the cost to repair damages exceeded 300 million córdoba ($14.5 million USD). Overall, Beta was responsible for nine fatalities and more than $15.5 million in damage across four countries.

On October 21, a westward-moving tropical wave entered the Caribbean. The wave quickly developed organized convection, indicating that a possible low-pressure area had developed along the wave. Continued development led to the formation of Tropical Depression Twenty-Five (which would later be named Alpha). The wave continued to move towards the west, producing minimal shower and thunderstorm activity. Once in the southwestern Caribbean, the wave slowed, and convection gradually redeveloped on October 25. The next day, with continued organization, the National Hurricane Center (NHC) stated that a tropical depression could develop in the following day or two. At around 18:00 UTC, the NHC determined that Tropical Depression Twenty-Six had developed about 105 miles (170 km) north of the central cost of Panama.
Located within an area of weak vertical wind shear and warm sea surface temperatures, the depression intensified. By 06:00 UTC the next morning, the depression was upgraded to a tropical storm and given the name Beta by the NHC. Beta was slowly moving towards the north-northwest in response to a mid-tropospheric shortwave trough over the Gulf of Mexico and mid-tropospheric ridge to the northeast of the storm. Deep convection developed near the center of circulation, signifying a developing system. With favorable conditions for development, Beta was forecast to intensify into a hurricane before making landfall in central Nicaragua. An eyewall rapidly developed around the center of circulation, fuelling further intensification. With the formation of an eyewall and the compact size of the storm, rapid intensification was anticipated. By the end of October 27, maximum sustained winds around the center of Beta were estimated at 60 mph (95 km/h). An increase in wind shear caused a minor disruption of the storm's structure, briefly preventing strengthening.
After maintaining its intensity for 30 hours, the shear weakened, and Beta began to intensify again. Around 00:00 UTC on October 29, the storm passed near Providencia Island with winds of 70 mph (110 km/h), just below hurricane-status. At this time, the cyclone began to turn towards the west. Beta intensified into a hurricane several hours later, with winds of 80 mph (140 km/h), as an eye became pronounced on infrared satellite images. Located south of a weakness within the subtropical ridge, the hurricane's motion slowed to a westward drift. With the formation of an eye, the chances of rapid intensification reached 62%, and the storm could possibly become a major hurricane—a hurricane with winds of 111 mph (178 km/h) or higher—before landfall. Beta continued to intensify as convection deepened around the 11.5 mi (18.5 km) wide eye, strengthening into a Category 2 hurricane with winds of 105 mph (170 km/h).
After undergoing a brief period of rapid intensification from 18:00 UTC on October 29 – 06:00 UTC on October 30, the hurricane reached its peak intensity as a Category 3 hurricane with winds of 115 mph (185 km/h) and a minimum pressure of 962 mbar (hPa; 28.42 inHg). The storm also began to turn towards the south-southwest as it reached its peak intensity and its maximum size, with tropical storm-force winds extending out 60 mi (95 km) from the center. However, as it neared the coast, cloud tops around the eye began to warm, signifying weakening. Around 12:00 UTC on October 30, Beta made landfall in central Nicaragua near La Barra del Rio Grande with winds of 105 mph (165 km/h). After making landfall, the hurricane weakened to a tropical storm, with winds decreasing to 65 mph (100 km/h), as the structure of the storm began to deteriorate. Early on October 31, Beta weakened to a tropical depression and dissipated a few hours later over the mountains of central Nicaragua.
Panama, Costa Rica and El Salvador
Although Panama and Costa Rica were not in the direct path of Hurricane Beta, storm warnings were issued for the two countries on October 27 as heavy rains, up to 20 in (508 mm), from the outer bands of Beta were possible. The Office for the Coordination of Humanitarian Affairs in Panama alerted officials in Nicaragua, Honduras, Costa Rica, El Salvador and Guatemala about the possible impacts from Beta. Civil defence officials in El Salvador declared a pre-emptive alert due to the possibility of rain-triggered mudslides from the outer bands of Beta.
Early on the morning of October 27 the Colombian Government issued a tropical storm warning for the islands of San Andrés and Providencia. Hours later, a hurricane watch was issued. By late morning, both advisories were replaced by a hurricane warning. The island did not have much time to prepare for Hurricane Beta, being struck only three days after its formation. Of its 5,000 residents all stayed to weather the storm but, about 300 of them evacuated wooden homes on the beach for sturdier brick shelters inland on the island's mountains. The neighbouring island of San Andrés initiated a moratorium on all outdoor activities as the storm's outer bands reached the island on October 29. Officials evacuated about 700 people, 500 tourists and 200 residents on San Andrés to temporary shelters. The Colombian Government provided 8 tons (7.2 tonnes) of food and emergency supplies, including 1,100 sheets, 300 hammocks, and 350 cooking kits to the island.
Immediately upon the storm's formation on October 26, the Government of Nicaragua issued a tropical storm warning for its entire eastern coast. The next day the tropical storm warning was supplemented by a hurricane watch. On October 29, Nicaraguan President Enrique Bolaños declared a maximum "red alert" for the country's eastern coast. Despite the governments efforts, only 10,000 people were evacuated from the Caribbean-side coast and the majority secured themselves in their homes. However, the national army reported that 150,000 people were evacuated prior to the storm's arrival. The government pre-positioned food, medicines, clothing, emergency supplies, and army rescue specialists in the most vulnerable areas to provide relief immediately after the storm passed. Classes were canceled in all of the country's schools and businesses experienced surging demand for hurricane supplies.
In the city of Puerto Cabezas, population 60,000, meteorologists expected a direct hit. Local authorities announced a curfew to prevent looting. The government also cut off electricity throughout the small coastal city to prevent injuries. Evacuations were limited, and the most vulnerable of the population weathered the storm in poorly constructed shelters. To be able to respond to an emergency following Beta, the government of Nicaragua requested relief supplies for 41,866 families which would last 15 days. These supplies consisted of 98,000 lb (44,452 kg) of cereals, 628,600 lb (285,128 kg) of beans, 628,600 lb (285,128 kg) of corn, 125,7200 lb (57,025 kg) of rice, 44,500 lb (20,184 kg) of sugar, 171,600 lb (77,836 kg) of salt, 4,929 gal (18,658 L) of cooking oil, 324,900 lb (147,372 kg) of milk and 21,264 blankets.
On October 29, Honduras President Ricardo Maduro declared a State of National Emergency as Beta was forecast to bring heavy rains up to 12 in (300 mm). Three departments, Gracias a Dios, Colon, Olancho and El Paraiso, were placed under Red Alert and mandatory evacuations were put in place. The departments of Atlántida, Yoro, Comayagua, Francisco Morazán and Choluteca were placed under Yellow Alert and a Green Alert was in place for the rest of the country. The Local Emergency Management Agency opened its regional and municipal offices to conduct preparative activities. An emergency radio network was set up to alert the public of any emergencies. The government designated several public schools as shelters for the affected population. In the Francisco Morazán Department, the Tegucigalpa Municipal Emergency Committee opened 73 shelters. Extensive cleaning and garbage disposal was conducted, especially around creeks, rivers, and sewers. The National Armed Forces were placed in strategic areas and were on stand-by for search and rescue operations once the storm passed. About 3,306 tons (3,000 tonnes) of food was reported to be available and local travels in the country were suspended. In Tegucigalpa, the emergency committee called for the evacuation of 125,000 people from the most vulnerable areas of the capital. About 8,000 others were evacuated from 50 communities along the Nicaragua border due to the threat of flooding. A hurricane alert was put in place for areas north of the Nicaragua border but was cancelled on October 30 after Beta turned towards the southeast.

Hurricane Beta was responsible for nine fatalities and roughly $15.5 million (2005 USD) in damage across four countries.
Heavy rains for the outer bands of Hurricane Beta, amounting up to 3 in (76 mm), caused flooding and landslides in Panama. At least 256 people were affected by the storm and 52 homes were damaged; however, the cost of the damages is unknown. At least 50 hectares (124 acres) of rice fields were flooded across the country. One person, a young girl, was killed after the boat she was on sank amid rough seas. Both her parents escaped the sinking ship. Two other people drowned after being swept away by the swollen Chagres River and two others were reported missing.
Hurricane Beta reached Providencia Island, on October 29, 2005. Rainfall from the storm were estimated over 12 in (304 mm). Roofs were damaged all over the island, and the island's main communications tower was knocked over. A total of 1,660 homes were damaged by the storm throughout the island, leaving 1.4 million Colombian peso (2005 COP; $681 USD) in repair costs. This disrupted fixed-line telephone service and as the island has no cellular telephone service, it caused a total cessation of communication with the mainland. Beta's arrival on the island was accompanied by a seven-foot storm surge, which damaged beaches, coastal houses and roads, and washed out a tourist footbridge. Coral reefs around the island were, for the most part, untouched, as only 1 percent of the coral sustained minor damage. Minor effects were also found around areas of sea grass. Beaches all around the island lost an average of 9.8 ft (3 m) of sand due to erosion. Thirty people were injured and 913 families, a total of 3,074 people, were affected during Hurricane Beta's passage over the island.

Heavy rains from Hurricane Beta, amounting up to 6.39 in (162 mm), and strong winds caused extensive property damage in Nicaragua. Six people were confirmed to have been killed by Beta in Nicaragua, one of which was caused by a heart attack. It was initially feared that ten others, who were listed as missing, were killed when their vessel disappeared during the storm. But they were later rescued by a Panamanian vessel after drifting in the waters for several hours. Throughout the country, a total of 376 latrines, 215 homes, two schools, two community children centres, two community water tanks and five solar panels were destroyed. An additional 852 homes, 21 schools, and three health centres were damaged. The cost to repair damages caused by the hurricane were estimated at $2.1 million (2006 USD). A total of 2,668 people were left homeless as a result of the storm.
Two communities of Miskitos, with a total population of 3,200, were isolated during the storm. Nearly 80 percent of the homes in four communities along the Caribbean coast near Bluefields were destroyed by the storm. The strong winds from Beta levelled 1,200,000 acres (4,900 km2) of forested land. Agricultural damage from the storm in Nicaragua amounted to 67 million córdoba ($4 million USD). Structural damage amounted to 35 million córdoba ($1.6 million USD). Damage to roadways throughout the country left over 20 million córdoba ($979,000 USD) in damages. Offshore, the damage to algae, mangroves, and other aquatic life was severe. Hundreds of dead fish washed up along the coastline in the days following Beta.
Torrential rains, peaking at 21.82 in (554 mm), caused numerous mudslides which isolated several communities. Widespread damage occurred to structures, with numerous roofs being torn off. Signs, trees, power poles, and telephone poles were knocked down due to the wind. Four rivers overflowed and communications were disrupted across areas near the Nicaragua border. An estimated 60,483 people were affected by the storm in the country. A total of 954 homes and 11 bridges were destroyed while another 237 homes, 30 roads, 30 bridges and 66 drinking water systems were damaged. A total of 7,692.1 acres (3,112.9 ha) of farmland was destroyed. At least 11,000 people were left stranded by the storm. Throughout the country, damage was estimated at 170 million lempira ($9 million USD).
On Providencia Island, two teams of aid personnel, consisting of a total of 800 people, from National Intervention Teams were mobilized in response to Beta. The Colombian Red Cross Society and the National Disaster Response and Preparedness System (SNPAD) provided assistance to 600 families with non-food relief, pre-hospital care, first aid, temporary shelter and psychosocial support, and carried out a preventative health campaign on the island. On October 29, Diego Palacio, the Minister of Social Protection, flew to Providencia to assess the damage caused by Beta. A frigate was also deployed to the island, carrying two tons of relief items along with 130 search and rescue workers. Reconstruction on the island took place shortly after the storm dissipated and 60 percent of the structures were repaired by January 20, 2006. The completion date for repairs was set at the third week of February.
The SNPAD in Nicaragua distributed food to 1,500 victims and reported that food was needed for an additional 35,000 people. Roughly 300 million córdoba was required to repair roadways throughout the affected region. On November 1, the government of Nicaragua announced that it would assist in the reconstruction and repair of 334 for the Miskito Indians. By November 7, airlifts from Managua were able to bring roughly 60 tons (54 tonnes) of supplies to natives living along the Coco River. Additionally, plans for a four-month operation to supply the Miskito Indians with food were implemented. In attempts to lessen the effects of disease and famine, 5,000 tons (4,536 tonnes) of food was planned to be distributed in the region during this time.
Ahead of Hurricane Beta, the U.S. ambassador to Nicaragua signed a disaster declaration on October 28, prompting the United States Agency for International Development (USAID) and Office of Foreign Disaster Assistance (OFDA) to send aid. Before the storm hit, $200,000 was sent to the country for emergency relief supply distribution and helicopter fuel. On November 1, USAID and OFDA airlifted 200 rolls of plastic sheeting, 5,020 ten-litre water containers, and 2,736 hygiene kits, valued at $120,877. Another $22,000 was used to supply an aircraft and Bell 204/205 helicopter to assist affected areas. On November 10, another $100,000 was sent for sanitation and health activities. The United Nations sent $10,000 to the South Caribbean Coast Autonomous Region to cover emergency needs. Forty-five tents were sent to communities in need. The Spanish Government also sent $377,188 in aid and to Nicaragua.
The International Red Cross and Red Crescent Movement sent 300 food packages, 300 kitchen kits, 200 mattresses, 300 hygiene kits, 150 hammocks, plastic sheeting, and 26.4 tons (24 tonnes) of construction materials and tools to Nicaragua. As a precaution, about 2.2 tons (2 tonnes) of food was also sent to the National Society's warehouse in Bogotá. A total of $116,367 was also allocated from disaster relief funds. The Justice, Global & Ecumenical Relations Unit in Canada also provided $6,500 in relief funds to Nicaragua. Two shipments of relief supplies were sent to the hardest hit areas by Direct Relief International. The first shipment arrived on November 9; it contained 3,000 lbs (1,360 kg) of antibiotics valued at $237,241. The second shipment arrived on November 22; it contained numerous supplies, valued at $139,283, which would be delivered to the hardest hit areas. The governments of Sweden and France sent $37,191 and $36,058 in funds respectively.
On October 31, a disaster declaration was signed for Honduras due to the effects from Beta. USAID sent $50,000 in funds for the purchase of relief items such as blankets, foam mattresses, and hygiene kits. Two Fokker F27 aircraft were also supplied to help assist the transportation of relief supplies at a cost of $40,000. The United States Department of Defense sent military personnel to the affected areas from November 4–8. During that time, more than 155,000 lb (70,306 kg) of relief supplies were airlifted to the affected communities. The United States embassy in Honduras also provided a C-12 Huron aircraft to transport 3,000 lb (1,360 kg) to Puerto Lempira. A total of $500,000 was sent in the form of relief supplies and transport to Honduras from USAID. The Spanish Government offered a C-130 Hercules containing emergency supplies to Honduras. The World Food Programme pre-positioned 509 tons (461.7 tonnes) of food to be used in temporary shelters and recovery activities. The government of Great Britain offered humanitarian assistance, consisting of 1,500 plastic bags, 1,800 jerrycans, one helicopter, five boats, 250 military personnel, and five medical assistants.
Naming and records
When Tropical Depression Twenty-six was upgraded to Tropical Storm Beta, it was the first time that the second letter of the Greek alphabet was used for a tropical cyclone. Upon being named, it was the first time that an Atlantic hurricane season had produced 24 tropical or subtropical cyclones. Operationally, Beta was the record-breaking 13th hurricane, surpassing the 12 hurricanes produced in 1969. In the post-season analysis by the National Hurricane Center, Tropical Storm Cindy was upgraded to a hurricane, thus making Beta the 14th hurricane of 2005. The name was not retired by the World Meteorological Organization in the spring of 2006, as the hurricane committee determined it "was not practical to 'retire into hurricane history' a letter in the Greek Alphabet." It remains on the auxiliary list of names in the event that another Atlantic hurricane season produces more than 21 named storms.
