 While moving across Trinidad, Alma produced sustained winds of only 35 mph (56 km / h) at Piarco. However, gusts reached 91 mph (147 km / h) at Savonetta. Rainfall at Piarco reached about 1 inch (25 mm) during the storm's passage. Strong winds downed trees and power lines, and damaged about 5,000 buildings, including hundreds of households, wrecking everything inside; this left about 500 people homeless. There was also widespread damage to agriculture, mostly to sugar, amounting to 17,750 acres (7,180 ha) of damaged fields. The storm damaged several highways in the country, along with damaged schools and hospitals. The winds flung debris from a roof of a house and struck a woman, killing her. There was also an indirect death on the island, along with several injuries. Damage on the island was estimated at $ 5 million (1974 USD), and Alma was considered the most destructive storm in Trinidad during the 20th century, according to the American embassy in the country. After the storm, the local Red Cross chapter provided meals and clothing to thousands of storm victims. The government allocated $ 5.1 million (Trinidad and Tobago dollars) for relief work, to be coordinated by the National Emergency Relief Organization of Trinidad and Tobago, which was established following the damaging Hurricane Flora in 1963. This helped rebuild damage houses, clear roads, and assist affected farmers. The United States Agency for International Development sent about $ 5,000 (USD) in assistance, after the country's ambassador sent a formal request to Washington, D.C. The Amoco oil company also sent a $ 500 (USD) donation to the country's Red Cross.
