A series of computer models constitutes the basis for a weather analysis system called Slosh (sea, lake, and overland surges from hurricanes). These models are being developed for east and Gulf coastal areas to assist in forecasting the effects of hurricane storm surges.
Although the opportunity to test Slosh in the extreme occurrence of maximum storm surges where water levels may rise 20 feet or more has not yet occurred, first test results of one of the models during a minimal force hurricane indicate that the system will work. The model developed for the New Orleans area, for example, was used during Hurricane Bob, in July 1979. The information generated by computer, based on data gathered from ships, satellites, aircraft, and radar observations, was helpful in preparing local warnings of potentially dangerous flooding.
