Geography and ecology of the Everglades is nourished primarily from the atmosphere. Before the first attempt at draining the Everglades in 1882, the entire watershed extended from Orlando to Florida Bay comprising the Kissimmee–Lake Okeechobee–Everglades (KLOE) watershed. Kissimmee River outlets flow into Lake Okeechobee, which sits above sea level. Only two seasons exist in the Everglades: wet (May to November) and dry (December to April). Average annual rainfall in the Everglades is approximately , though fluctuations of precipitation are normal. Droughts, floods, and tropical storms are normal occurrences in the area. When Lake Okeechobee exceeds its water storage capacity during the wet season, it pours slowly
Effects of the 1928 Okeechobee hurricane in Florida pressure below 940 mbar (27.76 inHg), the others being the 1926 Miami hurricane and Hurricane Andrew of 1992. Because of well-issued hurricane warnings, residents were prepared for the storm, and the number of lives lost in the coastal Palm Beach County was only 26. However, it is estimated that there were at least 2,500 deaths, primarily in the areas surrounding Lake Okeechobee. Around 75% of the fatalities were migrant farm workers, making identification of both dead and missing bodies very difficult; as a result of this, the count of the dead is not very accurate. The Red Cross estimated the
