; to measure windspeed, barometric pressure, humidity, and temperature as they fall to the surface of the ocean. By sampling the cyclone with these dropsondes over a 4,000 mile track around the storm, the forecasters at NOAA's National Hurricane Center and Hurricane Research Division can better predict where the hurricane will be "steered" by the upper level winds. They also predict wind shear that will either increase or decrease a hurricane's strength. The GIV-SP

, 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.

1997 The HPC issues storm summaries on storm systems bringing significant rainfall and snowfall to portions of the United States. Advisories are also issued for tropical cyclones which have moved inland, weakened to tropical depression strength, and are no longer the responsibility of the National Hurricane Center. The HPC also acts as the backup office to the National Hurricane Center in the event of a complete communications failure. NMC changed its name to NCEP, the National Centers for Environmental Prediction on October 1, 1995. The HPC become a subunit of NCEP, as did a number of other national centers such as the Climate Prediction Center, Environmental Modeling Center, National Hurricane Center, Ocean Prediction Center, Storm Prediction Center, Aviation Weather Center, NCEP Central Operations, and the Space Environment Center.

historical work

Tropical Depression Twelve formed over the southeastern Bahamas at 5:00 p.m. EDT (Eastern Time Zone) (2100 UTC (Coordinated Universal Time)) on August 23, 2005, partially from the remains of Tropical Depression Ten (Tropical Depression Ten (2005)), which had dissipated due to the effects of a nearby upper tropospheric (troposphere) trough (trough (meteorology)). While the normal standards for numbering tropical depressions in the Atlantic (Atlantic Ocean) indicate that the old name number is retained when a depression dissipates and regenerates, satellite data indicated that a second tropical wave combined with Tropical Depression Ten north of Puerto Rico to form a new, much more advanced system, which was then designated as Tropical Depression Twelve.

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.
