NHC has changed the low probability (10%) area with an elonged area to watch now up the western side of the GOA. Some guidance suggests a weak low could travel over water for a longer period of time or come off Mexico.
This change doesn't represent a change in confidence in development, but rather a change in where it could develop. The bottom line is it could spend more time over the GOA and frankly that is the only takeaway from this at this time. It certainly make it more interesting, but its still a low porbability event. Enhanced HEAVY RAIN remains the primary threat.
