Tropical Storm Joyce formed earlier today, tying the record for the 2nd earliest date that a "J" storm has formed in a season. This new storm isn't a threat to the U.S., but Isaac still is. The new forecast track has me concerned because the storm is now more likely to end up in the warm Gulf of Mexico instead of making a Florida landfall as earlier thought. See what's steering the storm and why there is still a lot of uncertainty.
