Faunsdale, AL | Yes……can’t buy a rain here in Alabama! We’re under a high pressure that diverted Helene to the east and North. Now Marvin is being shunted more to the East instead of tracking more to the North and then North East like most storms in the Gulf do.
If the storm behaves as predicted it’s going to be getting shear and dry air entrained into the circulation from the high pressure to the north of it. That’s the source of the weakening that’s predicted before landfall. We will see how well the models predict it.
Katrina was a similar storm that rapidly strengthened to CAT 5 strength before coming ashore along the Mississippi coast as a CAT 3. Everybody remembers New Orlesns flooding because of levee failures, but the storm surge damage along the coast was devastating. The size and storm surge produced by a storm that has recently been stronger is usually much worse than the wind speed at landfall would normally produce. | |
