Title: National Hurricane Center upgrades Isaac to hurricane

The National Hurricane Center has announced Isaac is officially classified as a hurricane with maximum sustained winds at 75 mph.

Isaac’s track has shifted to the west, putting Baton Rouge on the east side of the storm, meaning the city will now experience stronger winds and heavier rains.


While the latest official forecast track keeps Isaac to the east of Baton Rouge, there is still reliable guidance that brings the storm near or west of the Capital City. The Storm Team emphasizes that considerable uncertainty remains and all residents of south Louisiana should prepare for potential hurricane conditions.

    Hurricane Issac may stall over the Louisianna areas, increasing the potential for flooding rains. And rains along the path, up the Mississippi River will also cause flooding into areas south of the path. So while winds may not be major, the flooding rain from this storm may be the real issue.

    Hurricane Issac has just now come ashore. The center of circulation is now over the mouth of the Mississippi River. This storm is a dud. No rain in front, no wind with the rain clouds to follow. But Issac did what it needed to do: Throw the Republicans off their game by cancelling Monday's event schedule. (The Republicans seem to have been thrown off their game by one thing or another all summer.)

      Correction: I was watching Issac on radar, and saw a gap in the clouds, which I took to be a sudden relocation of the "eye" to the north, over land, as happens from time to time. After consulting three weather sites, I see that what has actually happened is a sudden shift of Issac's path to the west, which will take the storm to the west of New Orleans. Landfall will now be over the town of Houma, Louisiana, several hours from now.

    This would mean 6-10 inches of rain, which might cause some flooding problems. Rainfall predictions haven't been upgraded since this morning.

    I know hurricanes sound scary, but many thunderstorms create microburst downdrafts that produce much more powerful surface winds. And Katrina and Rita took out anything that a Cat 1 might damage. The wind of a Cat 1 does relatively little damage past the coastline surge zone. If you ever stuck your arm out the window going down the highway, you know what a Cat 1 feels like. I've been outside in them several times to secure loose debris from the neighbors. Cat 3, at 120 mph, is the point where hurricanes get scary.

    As far as scattering, the rain is going to ground most of the airborne toxins before the winds gets there to scatter it. Winds just don't have that big of an effect on geological structure below the surface. So it shouldn't trigger a release or cause sudden sinking. At most, it may knock over a few cypress trees in the subsidence zone, which would fall anyway.

    Rainfall is the real issue. I have seen minor tropical storms do considerably more damage than Cat 2 or 3 hurricanes because of the rainfall amounts. Wind speed is no indicator of how wet a storm is going to be. And keep in mind that rock is heavier than water, so flooding isn't that big of a factor below the ground in a place that is already flooded. Aquatic scattering of toxins is the issue.

      Won't be bad if the flooding helps to make visible how devastating fascking fluids are.
      Let's take samples, let's share the pain! 😉

    Isaac will move slowly into Louisiana, causing wind speed damage from surge and flooding across the Gulf States. The wind is not the issue here, the issue is with the building swell under the system's low pressure, including over 20 inches of rain, possibly higher around the storm.

    Other Hurricanes of the past with this low of pressure have had winds over 100 mph already. The wind isn't the killer, it is the surge and flooding caused by the storm.

    One must remember that although Hurricane Katrina hit category five status out in the Gulf, it weakened to a category three at landfall, weakening further to a one. The damage in New Orleans happened with category one winds from the northeast. It did not happen with category three winds as it was further away from the landfall point.

    The category system needs to be redone. My viewers must understand that although this is a Tropical Storm, almost a category one … that you need to understand the effects will be deadly, with surge and flooding being the main issue, that of category three or four conditions.
