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.

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 (US$14.5 million). Overall, Beta was responsible for nine fatalities and more than $15.5 million in damage across four countries.

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

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 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

Early on October 31, Beta weakened to a tropical depression and dissipated a few hours later over the mountains of central Nicaragua.

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.
Nicaragua
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
