Landfall at 95 knots.

So this is what the Hrd surface maps show Ivan. I think it was a cat5 at all three of its peaks. At around 140 knots. In with the 910 millibars to support it. As it was over the warm eddie over the mid Gulf it had reached cat4 again. Then weaken to a strong cat2 as it was moving into the coast.
Interesting none the less...
Arlene was 62 knots max over the central Gulf. Which using the same stardard would more likely be slightly stronger. As it weaken early that morning. But had tighten to 56 knots as it was moving inland from the 43 knots earlier.
Lets discuse.

What do you mean this is not recon? If I'm not mistaken, these graphics are driven from a mesh of all sorts of observations. The landfall graphic of Ivan even says that the analysis is based from ASOS, CMAN, Tower, SFMR, dropsonde, METAR, and buoy data. SFMR and dropsonde would represent recon...
