I'm not a fan of either the local news or the weather channel - too much drama in with carefully edited information. Their job is to scare you into leaving. My preference is Weather Underground -
www.wunderground.com. Click on severe weather then tropical, and you see a map of all the storms in both oceans. Click on Isaac, and a page with a lot of information will come up.
Latest information is that it will go into SE LA as a Cat 1, but there's still a lot of uncertainty.. The track has moved slowly west with landfall moving from FL to AL to MS and now LA. The track they show is kind-of the average of the models - not really an average, but "average" is a good enough word to describe how they're approaching the differences in the models.
One of the things I like about this site is that you can read the forecaster "discussion." While there's a lot of tech speak, there's enough English that anyone can get the jist of what the forecaster is saying.
Coast Encounter, if you are in a low area, get out. This is a very large storm, we're going to be on the strong (eastern) side, and it will be pushing a lot of water toward the MS Coast. I'm high, and I'm going to stay unless it turns more north and intensifies.
Mina, if you're heading to Houston on Wednesday, you'll be going right through the middle of it, since that's about when it will make landfall. Be very careful if you're driving. Not sure if planes will be flying.
Everyone be careful and make good decisions about whether or not to stay!
