It will be recorded as the second most costly storm ever to strike the United States, if Hurricane Agnes, which in 1972 caused inland flooding over a large part of the U.S. East Coast, is excluded. Alicia's coastal property damage was exceeded only by that of Hurricane Frederic, which came ashore near Mobile, Alabama, in 1979. Though Alicia was not a strong hurricane, the area of maximum winds in the storm crossed a large metropolitan area--the Galveston-Houston area of Texas (see Figure l.l)--placing that area's network of expensive structures, buildings, and lifeline facilities at risk. Wind damage was extensive throughout the area, and rain and storm surges caused flooding damage in some areas bordering the Gulf of Mexico and Galveston Bay. A unique effect of the storm was concentrated damage to the glass of a cluster of high-rise buildings in downtown Houston. "It was a hypnotic thing to watch," said a spokesman from the city's Public Works Department who observed damage in downtown Houston from a police squad car. "A panel would break out, but it wouldn't fall directly to the ground. It would get whipped around in the wind, hit another panel, maybe in the building across the street, and then there would be more broken glass flying around. It seemed to be feeding on itself." Other residents of the area reported being scared, lying in the dark listening to the wind roar, glass breaking, and flying debris hitting around them. For some, the storm was fatal. Tallies of the death toll from Alicia vary from 10 to 20, depending on the extent to which deaths indirectly attributable to the storm are included. The purposes of this report are to document the storm's characteristics and effects, to call attention to specific characteristics, effects, and storm-related conditions that could be studied further with beneficial results, and to examine the warnings, responses, and recovery occasioned by the storm. The report is based on a four-day survey by team members on August 23-26 of the conditions after the storm and on oral and written follow-up. file:///G|/John%20Eringman%20-%20Do%20Not%20Delete/H...PSsite/USHESdata/Assessments/alicia/introduction.htm (1 of 7) [10/28/2009 2:17:30 PM] INTRODUCTION AND OVERVIEW METEOROLOGY Hurricane Alicia was the first tropical cyclone of the 1983 Atlantic hurricane season. It was also the first hurricane to strike the continental United States since Hurricane Allen made landfall near Brownsville, Texas, on August 10, 1980. The period of slightly over three years between these hurricane strikes is the longest time the mainland of the united States has gone without a hurricane landfall in recorded history. The next longest hurricane-free period was from September 28, 1929, to August 14, 1932. file:///G|/John%20Eringman%20-%20Do%20Not%20Delete/H...PSsite/USHESdata/Assessments/alicia/introduction.htm (2 of 7) [10/28/2009 2:17:30 PM] INTRODUCTION AND OVERVIEW Hurricane Alicia made landfall on the extreme western tip of Galveston Island during the predawn hours of Thursday, August 18, 1983. The storm had developed rapidly over the north-central Gulf of Mexico during the previous 24 hours. When it made landfall, it was slightly above average in terms of size and intensity. Research aircraft of the National Oceanic and Atmospheric Administration (NOAA) made measurements in the storm until it came ashore. In addition, the storm made landfall near several major weather offices and radar facilities. As a result, Alicia is one of the best documented hurricanes ever to affect the United States. Some unusual aspects of Hurricane Alicia that are documented in this report include its rapid strengthening in the 12 to 18 hours prior to landfall, its rather sharp turn to the right (toward the northnorthwest) during the afternoon of August 17, and the double concentric eyewalls of the hurricane during the few hours prior to and just after landfall. Also, Hurricane Alicia was the first storm for which a new "probability" system of predicting hurricane landfall was used. Under this system, the probabilities of a hurricane's landfall are given and updated in each advisory issued for the storm, as described in Chapter 6. Twenty-three tornadoes were reported to the National Weather Service (NWS) Severe Storms Forecast Center in Kansas City in association with Hurricane Alicia (National Climatic Data Center, 1983). However, subsequent damage surveys have not corroborated this number of tornadoes. Preliminary reports indicate rainfall totals for the storm of 10 to 11 in., which is below average for Gulf Coast hurricanes that make landfall (average peak values are roughly 10 to 15 in. for other hurricanes in the Gulf of Mexico; see, for example, Parrish et al., 1982, and Miller, 1958). STORM SURGES AND SHORE PROCESSES More than two days before Alicia crossed the Texas coast, water levels along the east Texas coast began to rise above normal levels. By midnight on August 16, the water level in front of Galveston Island was about 2 ft above normal tide level. The disparity had increased to more than 3 ft by 6 p.m.
