NOAA
MOBILIZES RESOURCES TO AID IN RECOVERY FROM HURRICANE KATRINA
Aug.
30, 2005 � NOAA quickly mobilized
a wide-range of its resources immediately following Hurricane Katrina’s
landfall on the U.S. Gulf Coast. NOAA ships, planes and many experts
are helping to assess the damage caused by the powerful storm that is
responsible for widespread destruction and loss of life. (Click

NOAA pre-positioned
Navigational Response
Teams, or NRTs, which are mobile emergency response units equipped
and trained to survey ports and nearby shore waterways immediately following
the hurricane. These teams can be rapidly transported on a trailer and
launched from them for a quick response. This is especially vital to
New Orleans, La., and Mobile, Ala., two of the nation's major commercial
ports. The NOAA Office of
Coast Survey, working in partnership with the U.S. Coast Guard,
the U.S. Army Corp of Engineers and local port management will be coordinating
the response.
The
Navigational Response Teams use multibeam, sidescan sonars and diving
operations to check the port, river or sea bottom for submerged obstructions
that could cause hazards to shipping. (Click NOAA aerial image

The NOAA
National Geodetic Survey is using a NOAA plane to take aerial surveys
of the impacted areas to assess for damage from erosion, such as occurred
to the levees and major evacuation routes. These images will assist
both in recovery operations, and long-term restoration and rebuilding
decisions. The images will be made available to the public on a NOAA
Web site on Wednesday.
The
NOAA Office of Response
and Restoration and Damage Assessment Center is deploying NOAA scientists
and other specialists—in coordination with federal, state and
local emergency centers—to assist in evaluating the damages to
the many oil and chemical pipelines and platforms in the region. (Click

Water levels,
storm surges and flooding are a concern, and NOAA staff is working closely
with the Department of Homeland Security and FEMA to coordinate the
flow of appropriate information and data that will guide deployment
of resources.

Hurricane Hunter Flies Day and Night Missions in Hurricane Katrina
The NOAA Gulfstream
IV high-altitude surveillance jet flew six full-endurance missions
and the WP-3D
Orion flew four missions to support the track and intensity forecasting
efforts of NOAA’s National
Centers for Environmental Prediction and National
Hurricane Center. Starting with the first mission when Katrina was
still a tropical storm in the eastern Bahamas, the crew flew daily between
August 24 and August 28, using dropwindsondes to measure the environment
surrounding the growing tropical cyclone. While conducting five daily
missions and one overnight flight—when Katrina grew strongest
and made the critical turn toward the Gulf Coast, the jet flew a total
of 49.7 hours in five days. The NOAA crew launched 153 dropwindsondes
covering 21,015 nautical miles of flight track.
Data
from the Gulfstream IV, quality assured while aboard the aircraft, was
fed by satellite communication directly into the primary NOAA forecasting
computer models. These data helped the NOAA National Hurricane Center
to first catch Katrina's turn toward the southwest as she reached hurricane
strength just before the South Florida landfall. (Click NOAA

Empire, Buras and Boothville where Hurricane Katrina made landfall on

The G-IV
continued its storm coverage as the tropical cyclone re-emerged into
the Gulf of Mexico and detected perfect atmospheric conditions surrounding
the storm for rapid development. As Katrina reached Category Five hurricane
status, the NOAA jet used dropwinsonde coverage to help the NOAA National
Hurricane Center accurately define the range of hurricane and tropical
storm force winds, while adding to the accuracy of the forecasted position
and time of landfall on the northern Gulf Coast.
A
full 60 hours out, the NOAA National Hurricane Center, assisted by these
reports, had the New Orleans and Gulf Coast area well within the cone
of strike probability. Twenty-four hours prior to landfall, the center
of the forecasted track was approximately 15 miles off the actual track,
and 12 hours prior, the forecasted track was less than 10 miles off.
At approximately 7:10 a.m. EDT, Hurricane Katrina made landfall in southern
Plaquemines Parish, La., just south of Buras, as a Category Four hurricane
with maximum winds estimated at 140 mph to the east of the center. (Click
