In a country where an inch of rain can fall in an hour, 120 or 130 inches in a year may not mean a great many more than 120 or 130 hours of rain all told. Some of the most torrential downpours lasted only a few minutes. But it did rain nearly every day and it never just rained. At Colón six inches in twenty-four hours or less was not uncommon. In the single month of November, when the heaviest storms struck, rainfall along the Chagres basin—on the Atlantic slope, that is—could range from two to three feet.
