Regarding the doom and gloom posts, a storm moving slowly 100 miles off the coast will not drive catastrophic surge into the coast. Water rise and wave buildup? Sure. Major surge? No. You need the wind energy driving the water inland. I’m not mitigating the threat, but if that Euro run verifies, everyone should breathe a sigh of relief in Tampa.
Other good news, a major system slowing down is usually the worst case for rainfall. In this case, Ian is slowing down while being shredded by shear and dry air. This looks to rip most of the moisture north of the circulation. This is not a prime setup for flooding at least in Florida there will likely be a large dry slot east of the center as the circulation injects dry air from the west.
Lastly, as far as windfield goes, I’m not seeing a massive system. This looks to be modeled as a pretty tight core. HWRF, HMON, EURO, GFS all barely skim the west coast of Florida with TS force winds. As it weakens, those winds do expand from the center but by that time I’m really not thinking a large fetch of 35-50 kt winds would be devastating.
Once again, I am not downplaying this system or it’s potential destruction. However, overnight the modeling trend would shed the core of destructive winds and surge west of the peninsula. We need to temper our doom and gloom for this storm if that scenario plays out, which thankfully would spare millions of people a very destructive hit. Still a lot of variables at play but to see the major modeling push west, the current position being SW of where the models that pushed this near or over the Tampa area yesterday, and continued hostile to extreme hostile conditions modeled across the northern GOM, it looks like we may have an “out” to avoid a destructive impact
