Hurricane Isaac continues to hold an impressive structure on radar and satellite presentation despite making not one but two landfalls along the Louisiana coast. The warm, moist, swampy land down across far southern Louisiana and slow forward speed in the single digits with a period in which it stalled, drifted west and hugged the coast, all […]
It would appear from the latest satellite presentation that Isaac’s eye is trying to become better organised right at the point it looks s as though it’s coming ashore on the southeastern tip of Louisiana. The warm, marshy terrain down here would suggest little weakening for some time yet and it wouldn’t surprise me if […]
Well interestingly, Isaac above all places to get it’s true act together is as it’s coming shore along the Louisiana coast. It’s officially an 80 mph Category 1 Hurricane but recent dropsonde measurements have confirmed the system is intensifying with pressures down to 971mb and may in fact continue falling before the center comes onshore […]
Isaac Has Had A Whole Host Of Problems To Contend With Well Isaac has just been declared a 75 mph, category 1 hurricane despite the look of one over the past 12 hours with an eye and eyewall feature with substantial convection circling this inner core. The issue has been that although winds aloft (at flight level) have been supporting […]
After a few hours sleep I’m back up and was half expecting to see a hurricane declared and a healthier looking storm, however, I am seeing little difference from when turning this computer off. The only difference to me is that it’s closer to the Gulf Coast and the dry air is shaving off convection on […]
For days now, Isaac has been fighting either shear, dry air or both. All day, there has been slow improvement in the system’s overall appearance with a better and better core showing. Pressure has been slowly falling and is now down to 981mb but official winds remain at 70 mph. This will be upgraded by the […]

While we fear the wind and storm surge aspect from Isaac over Southeast Louisiana, Mississippi and Alabama, there is also a very concerning trend on models. Models have this system near stalling just inland with little movement from an early Wednesday landfall through Friday with the center merely covering a distance of 50-100 miles inland from the […]
