Alma produced devastating rainfall across Central America , with peak accumulations of 14.82 in ( 376.4 mm ) in Quepos , Costa Rica . The nearby cities of Guanacaste and Puntarenas were most heavily affected with over 1,000 homes damaged , of which over 150 were destroyed . Throughout all of Costa Rica , more than 100 roads and bridges were damaged , leaving several communities isolated for several days . In Nicaragua , the departments of León and Chinandega saw approximately 200 homes damaged ; across Honduras , an additional 175 homes were adversely impacted . Six people died in Honduras : a young girl who was swept away by a fast-moving river and five people who perished following the crash of TACA Flight 390 . Two more deaths occurred in Nicaragua due to electrocutions from downed power lines , and one death occurred offshore when a fishing vessel sank . Nine people on boats went missing in the wake of the cyclone . A westward-moving tropical wave departed the western coast of Africa on June 14 and entered the eastern Pacific a week later . A broad surface low formed in association with the feature south of the Gulf of Tehuantepec on June 23 , and its organization led to the development of a tropical depression around 06:00 UTC on June 27 . The cyclone only slowly organized in a moderate wind shear regime , becoming Tropical Storm Boris six hours later and remaining fairly steady state for a few days thereafter . Shear lessened on June 29 , allowing Boris to attain hurricane intensity two days later as an eye developed . This feature was temporarily eroded late on July 1 , but reappeared by 06:00 UTC on July 2 when the cyclone attained peak winds of 80 mph ( 130 km/h ) . Cold waters and a more stable environment then prompted rapid weakening , and Boris ultimately degenerated to a remnant low by 12:00 UTC on July 4 . The post-tropical cyclone continued westward until dissipating early on July 6
