Major Hurricane Isidore.... You have to Wander
Sat Sep 21 2002 11:12 AM
3:30 PM Update
Tropical Depression 13 Will be forming near 10.4N 44.9W (East of the caribbean islands) at 5PM, track expected to strengthen into a storm over the next few days. More later.
Recon reports Isidore's pressure drop to 946 millibars.
Isidore is strengthening, and aircraft recon found evidence of a mesovortex (Tornado-like "mini eyes" within the eyewall of a major storm that tend to cause Andrew scale ground damage). Which suggests we may have a category 4 hurricane in the gulf soon. It has slowed its forward motion. I still think it'll scoot a bit more west, but now I think the chances for a northerly turn are greater now. Still the Entire Gulf, especially LA to Alabama needs to watch. This story is not over by a long shot.
Bad puns in topics aside, we now have a Category Three Hurricane moving slowly in the Gulf, near the Yucatan Peninsula, that may be in the Gulf for quite a while.
This is both good and bad, good because upwelling may occur and the environment may change to actually keep Isidore's strength in check or weaken, bad because it's a major hurricane in the Gulf that models are going wild with. So it may not decrease.
For example, this mornings GFDL model run shows the storm hanging out in the Bay of Campeche. This still makes the strike zone anywhere in the Gulf from Mexico to Florida, and is a little unsettling. Why, some of the other models, which are longer range, have it heading north after a while, and potentially restrengthening again. The length of time this system will wander around will continue to give EM folks around the gulf coast a headache, and everyone else will need to watch it. Mexico to Florida... still. Concentrating on the north central Gulf coasts from tX/LA to FlAL lines. However, if it slides more westward Mexico may get it (Watch the trends). Although I don't think it'll landfall in the Yucatan.
Kyle is a subtropical storm and is also not going anywhere fast. And two more waves in the open Atlantic will have to be watched. As they may near the Caribbean later.
