Incredible by Modern Standards— June 1

New Orleans is a weather town. As hurricane season begins, hear the most emotional federal weather bulletin ever written. Plus, more on how the National Weather Service is using social science to improve forecasts. And hear from New Orleans residents who say the argument to call our 2005 disaster “The Federal Flood” instead of just “Katrina” still holds water. Why that weather wording matters.

South Louisiana has slowly ground to a halt as a winter storm dumps snow, sleet and freezing rain from Lafayette through coastal Mississippi.

The National Weather Service says moderate to heavy sleet continues across most of the region, and a Winter Storm Warning remains in effect for metro New Orleans. The NWS says the Winter Storm Warning is expected to last until Wednesday morning, and will likely be replaced by a Hard Freeze Warning once precipitation finally ceases.

The National Weather Service's New Orleans office has issued a freeze warning tonight for portions of southeast Louisiana and southern Mississippi.

The NWS says temperatures will rapidly drop to freezing, or just below it, shortly after midnight tonight, and remain there until after sunrise. The warning is in effect from midnight tonight to 9 a.m. Thursday, along and north of Interstate 12, and for all areas of coastal and southwest Mississippi.

The National Weather Service's New Orleans office has released an updated series of maps indicating the projected impact of Tropical Storm Karen on the metro area.

The NHS warns that maps such as these are subject to change based on a wide range of factors as the storm approaches. This post will be updated with new maps as the storm progresses.

The National Weather Service says the Concordia Parish town of Clayton got 7.2 inches of rain Wednesday and Thursday.

Mayor Rydell Taylor says the town of 700 looks like a lake, and water got into six to 10 homes. Taylor says a waterworks employee carried about a dozen children across flooded yards to their school bus, and he himself carried a disabled woman to the bus that takes her to work.

Taylor says nobody has been hurt, and water levels were dropping by late Thursday morning.

Louisiana may have a day or two of sun after the storms that swamped the state, but forecasters say rivers and streams will still be high and the ground will still be soggy when the next round of rain hits over the weekend.

Christopher Bannan, a National Weather Service meteorologist in Slidell, says storms probably will start late Saturday in north Louisiana and work southward through the state Sunday and Sunday night. He says the next round of storms likely won't be as potent as those that occurred Wednesday and Thursday.

The National Weather Service says an industrial plant in Iberville Parish may have been damaged by a tornado as heavy storms moved through the area Thursday morning.

No injuries were reported.

Iberville Parish Emergency Preparedness officials say the SNF Flopam plant about a mile south of Plaquemine reported roof damage around 7:30 a.m. The plant makes water-soluble polymers.

In Breaux Bridge, St. Martin Parish authorities said high wind tipped over a trailer, but the occupant was not injured.

Isaac might not be in the same league as Hurricane Katrina seven years ago, but the latest storm to batter Louisiana's Gulf Coast is punching above its weight class in more ways than one, scientists say.
