Emergency workers in Guatemala, Honduras and El Salvador are struggling to get aid to communities cut off by Tropical Storm Agatha. <br/><br/>The storm has left at least 150 people dead since Saturday, most of them in Guatemala. Rescuers are digging through mud and rubble in search of dozens of people still missing after landslides destroyed entire communities. <br/><br/>The storm has passed but officials warn that swollen rivers still pose a risk. The Guatemalan authorities said 123 people were known to have died, while in Honduras 14 people were killed, and nine in El Salvador.<br/><br/>All three countries have declared emergencies in an attempt to increase immediate aid and resources. The Gautemalan government said the storm dumped more than 3ft of rain on parts of the country, causing rivers to burst their banks and hillsides to collapse. <br/><br/>Guatemala's main airport is still closed to commercial flights because of the eruption of the Pacaya volcano last week, slowing the arrival of international help. <br/><br/>El Salvador's President, Mauricio Funes, said the risk of further destruction was still high. Authorities said most of the countries roads had been affected by landslides.
