Houston's massive population boom was reversed when oil prices fell in 1986 (1980s oil glut), leading to several years of recession for the Houston economy. The space industry also took a blow that year with the explosion of the ''Challenger'' (Challenger disaster) in Florida. The first nine months of 1987 saw the closure of eleven banks, but also the opening of several cultural centers including the George R. Brown Convention Center, the Wortham Theatre, and the Menil Collection. On August 7, 1988, Congressman Mickey Leland died in a plane crash in Ethiopia. On October 3, a Phillips 66 plant exploded in adjacent Pasadena, Texas, killing 23 and injuring 130. The Houston Zoo began charging admission fees for the first time in 1988.

Laboratory While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves and damaging storm surge.

, the storm weakened just before landfall to Category 3 intensity. The reasons for this weakening are not completely known yet; while the eye-wall replacement cycle played a part, slightly increasing shear (wind shear), dropping sea-surface temperatures, dry air on the western semicircle of the storm and interaction with the continental landmass also may have played a role in weakening the cyclone. This follows the trend of previous strong cyclones in the Gulf of Mexico: all cyclones with minimum central pressures (atmospheric pressure) of 973 mbar (28.73 inHg) or less have weakened over the 12 hours before making landfall (landfall (meteorology)) in the Gulf Coast of the United States. Katrina maintained hurricane strength well into Mississippi, but weakened thereafter, losing hurricane strength more than 150 miles (240 km) inland, near Meridian, Mississippi. It was downgraded to a tropical depression near Clarksville, Tennessee and broke in half.

National Hurricane Center

The '''National Hurricane Center''' ('''NHC'''), located at Florida International University in Miami, Florida, is the division of the United States' National Weather Service responsible for tracking and predicting weather systems within the tropics between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific ocean and the 31st parallel north in the northern Atlantic ocean. Its Tropical Analysis and Forecast Branch (TAFB) routinely issues marine forecasts, in the form of graphics and high seas forecasts, for this area year round, with the Ocean Prediction Center having backup responsibility for this unit. The Technology and Science Branch (TSB) provides technical support for the center, which includes new infusions of technology from abroad. The Chief, Aerial Reconnaissance Coordination, All Hurricanes (CARCAH) unit tasks planes, for research and operational purposes, to tropical cyclones during the Atlantic hurricane season and significant weather events, including snow storms, during winter and spring. Research conducted to improve operational forecasts is done through the Hurricane Forecast Improvement Project (HFIP) and Joint Hurricane Test Bed (JHT) initiatives.

During the Atlantic (Atlantic hurricane season) and northeast Pacific hurricane seasons, the Hurricane Specialists Unit (HSU) issues routine tropical weather outlooks for the northeast Pacific and northern Atlantic oceans. When tropical storm or hurricane conditions are expected within 48 hours, the center issues the appropriate watches and warnings via the news media and National Oceanic and Atmospheric Administration (NOAA) Weather Radio (NOAA Weather Radio). Although the NHC is an agency of the United States, the World Meteorological Organization has designated it as Regional Specialized Meteorological Center for the North Atlantic and eastern Pacific, making it the central clearinghouse for all tropical cyclone forecasts and observations occurring in these areas. If the center loses power or becomes incapacitated in some manner, the Central Pacific Hurricane Center backs tropical cyclone advisories and tropical weather outlooks for the northeast Pacific ocean while the Weather Prediction Center backs up tropical cyclone advisories and tropical weather outlooks for the north Atlantic ocean.
