get authentic official KATRINA updates here -->
http://www.nhc.noaa.gov/text/refresh/MIATCDAT2+shtml/281454.shtml

a somewhat technical update on the hurricane from NOAA but you will understand the important parts. Official updates every several hours or so. 11 am central time:

"THE AIR FORCE HURRICANE HUNTERS JUST MEASURED A 166 KT FLIGHT LEVEL
WIND IN THE NORTHEAST EYEWALL...WHICH REQUIRES AN ADDITIONAL UPWARD
ADJUSTMENT OF THE CURRENT INTENSITY TO 150 KT. A DROP IN THE EYE
GAVE A CENTRAL PRESSURE OF 907 MB. KATRINA IS COMPARABLE IN
INTENSITY TO HURRICANE CAMILLE OF 1969...ONLY LARGER. GPS
DROPSONDE DATA FROM THE NOAA G-IV MISSION EARLIER TODAY SHOWED
KATRINA'S INTENSE CYCLONIC CIRCULATION EXTENDING THROUGH THE 200 MB
LEVEL...WITH THE FLOW SPIRALING ANTICYLONICALLY OUTWARD IN A
WELL-DEVELOPED UPPER-LEVEL OUTFLOW PATTERN BEYOND A COUPLE HUNDRED
N MI FROM THE CENTER. FLUCTUATIONS IN STRENGTH...DUE TO INTERNAL
STRUCTURAL CHANGES...ARE LIKELY PRIOR TO LANDFALL. HURRICANES
RARELY SUSTAIN SUCH EXTREME WINDS FOR MUCH TIME. HOWEVER WE SEE
NO OBVIOUS LARGE-SCALE EFFECTS TO CAUSE A SUBSTANTIAL WEAKENING THE
SYSTEM...AND IT IS EXPECTED THAT THE HURRICANE WILL BE OF CATEGORY
4 OR 5 INTENSITY WHEN IT REACHES THE COAST."


not like the media whore news sites or the corporate cookie laden site of weatherunderground (sheesh I went there and got 18 cookies just from the front page alone).

PS - 150 knot wind = 175 mph sustained
166 knot gust = 190+ mph gusts

1. definition of Category 5
Category Five Hurricane:


Winds greater than 155 mph (135 kt or 249 km/hr). Storm surge generally greater than 18 ft above normal. Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the center of the hurricane. Major damage to lower floors of all structures located less than 15 ft above sea level and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the shoreline may be required. Only 3 Category Five Hurricanes have made landfall in the United States since records began: The Labor Day Hurricane of 1935, Hurricane Camille (1969), and Hurricane Andrew in August, 1992. The 1935 Labor Day Hurricane struck the Florida Keys with a minimum pressure of 892 mb--the lowest pressure ever observed in the United States. Hurricane Camille struck the Mississippi Gulf Coast causing a 25-foot storm surge, which inundated Pass Christian. Hurricane Andrew of 1992 made landfall over southern Miami-Dade County, Florida causing 26.5 billion dollars in losses--the costliest hurricane on record. In addition, Hurricane Gilbert of 1988 was a Category Five hurricane at peak intensity and is the strongest Atlantic tropical cyclone on record with a minimum pressure of 888 mb.
