The most important information I took from Masters' blog was :

"The NOAA jet is scheduled to fly tonight, so we'll have our first set of higher-reliability model runs Monday morning. The NOAA P-3 gets its first action Monday morning, and will fly their SFMR instrument that measures surface winds over the entire area."

We've seen over the past two seasons how imperative it is to have as much atmospheric data as possible. I think that once this information gets collected the track will become a bit more concrete.

For plotting lat/long I've installed Google Earth.
