Stamen has taken a step towards the concrete with their recent Hurricane Tracker for MSNBC. From what I can tell, it updates every couple of hours or so. The tracker shows where Hurricane Gustav has been and where it's headed and provides information on wind speed, ground speed, and location.
From the map we see a development from tropical depression in the Caribbean Sea, to a big category 4 over Pinar Del Rio, and then something between a category 3 and 2 as it moves over New Orleans. Gustav dwindles to a tropical storm as it moves towards Dallas. With mandatory evacuations of New Orleans starting yesterday, here's to hoping everyone finds somewhere safe to stay.
