TEGUCIGALPA, Honduras – Tropical Storm Matthew roared over Central America on Saturday, dumping heavy rains on disaster-prone parts of Honduras and Nicaragua and leading to the evacuation of thousands amid fears of flooding and mudslides. The storm made landfall Friday on Nicaragua's Caribbean coast and quickly crossed into Honduras where it was pushing inland with winds of 50 mph (85 kph) toward Guatemala and Belize. It was expected to weaken into a tropical depression on Sunday. Nicaraguan authorities said they ordered the evacuation of 10,000 people. In Honduras, authorities said they had evacuated 300 people from small communities in the Gracias a Dios province, on the border with Nicaragua. Lisandro Rosales, head of the country's Contingencies Commission said a red alert had been extended from six provinces to the whole country. In the capital city of Tegucigalpa, thousands of residents rushed to gas stations, supermarkets and banks after authorities recommended people stock up on food and other supplies and warned of three days of torrential rains. Authorities said classes would be suspended until further notice and that 15,000 schools had been made available to be used as shelters. A tropical storm warning also was in effect for the coast of Belize. Forecasters said the storm will reach the Guatemala-Belize border by Saturday night. Nicaraguan President Daniel Ortega ordered the preventive measures and "all emergency structures are on alert," Lt. Col. Freddy Herrera told The Associated Press by telephone. "We have evacuated people from the region of Cabo Gracias a Dios and the Miskito Cays" in the same region. Flights into the area were suspended due to limited visibility, though the winds are moderate, the military said. In Honduras, the government declared a state of preventive alert throughout the country and Defense Minister Marlon Pascua said the army was ready to help civil defense actions.
