The ninth tropical storm and seventh hurricane and major hurricane of the season, Hattie originated from an area of low pressure that strengthened into a tropical storm over the southwestern Caribbean Sea on October 27.

The Belize river valley is largely tropical rain forest . Also known as the Old River , the Belize River begins where the Mopan River and Macal River join just east of San Ignacio , Belize ( 17 ° 11  N 89 ° 04  W ) . The Belize River -- Mopan River Catchment contains over 45 percent of the population of Belize . The Belize River , in spite of 78 runs or rapids , is passable via the Mopan to the Guatemalan border .

Today the Belize River is a vital source of drinking water and other domestic use for local people living along the river ; however , water quality is degraded from sediment , nutrient loading , pesticides and other toxins . The major source of degradation is the extensive deforestation in the upper reaches of the Mopan River and non-sustainable agriculture . Karper and Boles have asserted : `` The greater Mopan / Belize River Catchment provides a prime example of a watershed under stress from extensive non-sustainable agricultural practices that have occurred within the region over the past three decades . '' Traditional slash and burn agricultural practices also contribute to watershed degradation ., Belize, formerly British Honduras, is a country on the eastern coast of Central America.
