Dangerous Category Four Hurricane Katrina Continues West-Northwestward But Expected To Turn Northward
A Hurricane Warning is in effect for the North Central Gulf Coast from Morgan City Louisiana eastward to the Alabama/Florida border including the city of New Orleans and Lake Pontchartrain.
A tropical storm warning and a hurricane watch are in effect from east of the Alabama/Florida border to Destin, Florida and from west of Morgan City to Intracoastal City, Louisiana.
At 5 am EDT (0900z), a Tropical Storm Warning has been issued from Destin Florida eastward to Indian Pass, Florida and from Intracoastal City, Louisiana westward to Cameron, Louisiana.
At 5 am EDT (0900z), the center of Hurricane Katrina was located near latitude 25.4 north, longitude 87.4 west or about 275 miles south-southeast of the mouth of the Mississippi River.
Katrina is moving toward the west-northwest near 10 mph. A gradual turn toward the northwest is expected later today.
Maximum sustained winds are near 145 mph with higher gusts. Katrina is a Category Four hurricane on the Saffir-Simpson scale. Some strengthening is forecast during the next 24 hours.
Hurricane force winds extend outward up to 85 miles from the center and tropical storm force winds extend outward up to 185 miles.
Estimated minimum central pressure is 935 mb (27.61 inches).
Coastal storm surge flooding of 15 to 20 feet above normal tide levels, locally as high as 25 feet along with large and dangerous battering waves can be expected near and to the east of where the center makes landfall.
Rainfall totals of 5 to 10 inches with isolated maximum amounts of 15 inches are possible along the path of Katrina across the Gulf Coast and the southeastern United States. The hurricane is still expected to produce additional rainfall amounts of 2 to 4 inches over extreme western Cuba and 1 to 3 inches of rainfall is expected over the Yucatan Peninsula.
Isolated tornadoes will be possible beginning sunday evening over southern portions of Louisiana, Mississippi, Alabama, and over the Florida Panhandle. (National Hurricane Center, media sources)
Hurricane Katrina Upgraded to Category 4
Coastal residents jammed freeways and gas stations as they rushed to get out of the way of Hurricane Katrina, which grew into a dangerous Category 4 storm early Sunday as it headed for New Orleans and the Louisiana coast. Katrina gained strength overnight, become a Category 4 with 145 mph sustained winds as it moved over the warm waters of the Gulf of Mexico early this morning. Katrina could become a Category 5 storm before landfall.
A hurricane watch extended from Louisiana to the Alabama-Florida border, and President Bush declared a state of emergency in Louisiana. His spokesman urged residents along the coast to heed authorities’ advice to evacuate. Katrina could be especially devastating if it strikes New Orleans because the city sits below sea level and is dependent on levees and pumps to keep the water out. A direct hit could wind up submerging the city in several feet of water.
Making matters worse, at least 100,000 people in the city lack the transportation to get out of town. The Superdome might be used as a shelter of last resort for people who have no cars, with city bus pick-up points around New Orleans.
Owners of gas stations in and around New Orleans were forced to direct traffic as lines to the pumps stretched down surrounding streets. Gas stations were running low on gas by midafternoon Saturday
Louisiana and Mississippi made all lanes northbound on interstate highways. Mississippi declared a state of emergency and Alabama offered assistance to its neighbors. Some motels as far inland as Jackson, Miss., 150 miles north of New Orleans, were already booked up.
By 2 a.m. EDT this morning, the eye of the hurricane was about 310 miles south-southeast of the mouth of the Mississippi River. It was moving west-northwest at about 8 mph and was expected to turn more to the northwest during the day, the National Hurricane Center said. “We know that we’re going to take the brunt of it,” Louisiana Gov. Kathleen Blanco said. “It does not bode well for southeastern Louisiana.”
Some tourists heeded the warnings and moved up their departures, and lines of tourists waited for cabs on New Orleans’ famed Bourbon Street. But plenty of people in the French Quarter stayed put, and bars were rocking Saturday night.
New Orleans’ worst hurricane disaster happened 40 years ago, when Hurricane Betsy blasted the Gulf Coast. Flood waters approached 20 feet in some areas, fishing villages were flattened, and the storm surge left almost half of New Orleans under water and 60,000 residents homeless. Seventy-four people died in Louisiana, Mississippi and Florida.
Katrina was a Category 1 storm with 80 mph wind when it hit South Florida on Thursday, and rainfall was estimated at up to 20 inches. Risk modeling companies have said early estimates of insured damage range from $600 million to $2 billion.
Katrina is the 11th named storm of the Atlantic hurricane season, which began June 1. That’s seven more than typically have formed by now in the Atlantic, Caribbean and Gulf of Mexico, the hurricane center said. The season ends Nov. 30. (Media Sources)

NExtremely Dangerous Category Four Hurricane Katrina Moving Northward Toward Southeastern Louisiana And The Northern Gulf Coast
A hurricane warning is in effect for the north central gulf coast from Morgan City Louisiana eastward to the Alabama/Florida border including the city of New Orleans and Lake Pontchartrain. Preparations to protect life and property should be completed this
evening.
A tropical storm warning and a hurricane watch are in effect from east of the Alabama/Florida border to Destin Florida and from west of Morgan City to Intracoastal City Louisiana.
A tropical storm warning is also in effect from Destin Florida eastward to Indian Pass Florida and from Intracoastal City Louisiana westward to Cameron Louisiana.
At 5 am edt (0900z) the center of hurricane Katrina was located near latitude 28.8 north longitude 89.6 west or about 90 miles south-southeast of New Orleans Louisiana and about 120 miles south-southwest of Biloxi Mississippi.
Katrina is moving toward the north near 15 mph and this motion is forecast to continue today. A gradual turn toward the north-northeast at a slightly faster forward speed is expected later tonight and tomorrow. On the forecast track Katrina will move onshore the southeastern Louisiana coast just east of Grand Isle this morning and reach the Louisiana/Mississippi border area this afternoon. Conditions will continue to steadily deteriorate over central and southeastern Louisiana, southern Mississippi, and southern Alabama throughout the day.
Maximum sustained winds are near 150 mph (240 km/hr) with higher gusts. Katrina is a strong category four hurricane on the Saffir-Simpson scale. Some fluctuations in strength are likely prior to landfall but Katrina is expected to make landfall as a category four hurricane. Winds affecting the upper floors of high-rise buildings will be significantly stronger than those near ground level.
Katrina remains a very large hurricane. Hurricane force winds extend outward up to 105 miles from the center and tropical storm force winds extend outward up to 230 miles. Recently, a sustained wind of 53 mph with gust to 91 mph was reported at Grand Isle Louisiana, and a wind gust to 71 mph was reported in New Orleans.
The minimum central pressure recently reported by an Air Force Reserve unit reconnaissance aircraft was 915 mb (27.02 inches).
Coastal storm surge flooding of 18 to 22 feet above normal tide levels, locally as high as 28 feet, along with large and dangerous battering waves can be expected near and to the east of where the center makes landfall. Some levees in the greater New Orleans area could be overtopped. Significant storm surge flooding will occur elsewhere along the central and northeastern Gulf of Mexico coast. NOAA buoy 42040, located about 50 miles east of the mouth of the Mississippi river recently reported waves heights of at least 46 feet.
Rainfall totals of 5 to 10 inches with isolated maximum amounts of 15 inches are possible along the path of Katrina across the gulf coast and the Tennessee Valley. Rainfall totals of 4 to 8 inches are possible across the Ohio Valley into the eastern Great Lakes region tomorrow and Wednesday.
The tornado threat ahead of Katrina continues to increase and scattered tornadoes will be possible today over southeastern Louisiana, southern Mississippi, southern Alabama, and over the Florida panhandle. (NWS National Hurricane Center)
National Weather
South
Hurricane Katrina should make landfall in eastern Louisiana or Mississippi during the morning hours. Katrina reached category 5 status yesterday morning and remains a powerful hurricane. Some fluctuations in intensity are possible prior to landfall, but Katrina is expected to remain a major hurricane as it impacts the Gulf Coast. A storm surge of 20 to 25 feet is possible along and to the east of the center of Katrina. On top of the water level rise (surge), waves of 20 to 40 feet are possible. West of the center, impacts should be less. Katrina is forecast to move north through eastern Mississippi/western Alabama tonight and early tomorrow. If Katrina maintains its current intensity and forward speed hurricane force winds could be felt up to 150 miles inland. Another concern inland will be the torrential rainfall, possibly 5 to 10 inches worth. The heavy rain in a short period of time could lead to fresh water flooding. Outside of Katrina other rainfall across the South is possible over Texas due to a decaying cold front.
