The forecast track keeps moving west. Yesterday it was going over Lake Maurepas just west of NO, now it's going over Lafayette. That's a westward shift of almost 120 miles in 24 hours. That makes evacuation plans difficult, especially since I'd rather go sooner than later but don't want to go to where the storm is going. My dad did this with Betsy. We evac'd NO to BR. Betsey came up the Mississippi river behind us. She was a bitch.
The oscillating strength is interesting. it was 4 yesterday, then a 3 before hitting Yucatan, expected to be 4 again later today and then degrade when it (hopefullly) runs into a dry air mass before making landfall.
This storm is more problematic than most.
