Anticipating A Flood Event
See also: Tropical cyclone rainfall forecastingWhile inland flooding is common to tropical cyclones, there are factors which lead to excessive rainfall from tropical cyclones. Slow motion, as was seen during Hurricane Danny (1997) and Hurricane Wilma, can lead to high amounts of rainfall. The presence of mountains/hills near the coast, like across much of Mexico, Haiti, the Dominican Republic, Central America, Madagascar, Réunion, China, and Japan acts to magnify rainfall potential due to forced upslope flow into the mountains. Strong upper level forcing from a trough moving through the Westerlies and its associated cold front, as was the case during Hurricane Floyd, can lead to high amounts even from systems moving at an average forward motion. Larger tropical cyclones drop more rainfall as they precipitate upon one spot for a longer time frame than average or small tropical cyclones. A combination of two of these factors could be especially crippling, as was seen during Hurricane Mitch in Central America. During the 2005 season, flooding related to slow-moving Hurricane Stan's broad circulation led to 1,662–2,000 deaths.

Famous quotes containing the words anticipating, flood and/or event:
“The Concord had rarely been a river, or rivus, but barely fluvius, or between fluvius and lacus. This Merrimack was neither rivus nor fluvius nor lacus, but rather amnis here, a gently swelling and stately rolling flood approaching the sea. We could even sympathize with its buoyant tied, going to seek its fortune in the ocean, and anticipating the time when “being received within the plain of its freer water,” it should “beat the shore for banks.””
—Henry David Thoreau (1817–1862)
“I am advised that there is an unexpended balance of about $45,000 of the fund appropriated for the relief of the sufferers by flood upon the Mississippi River and its tributaries, and I recommend that authority be given to use this fund to meet the most urgent necessities of the poorer people in Oklahoma.”
—Benjamin Harrison (1833–1901)
“It is known that Whistler when asked how long it took him to paint one of his “nocturnes” answered: “All of my life.” With the same rigor he could have said that all of the centuries that preceded the moment when he painted were necessary. From that correct application of the law of causality it follows that the slightest event presupposes the inconceivable universe and, conversely, that the universe needs even the slightest of events.”
—Jorge Luis Borges (1899–1986)
