Isaac nearly a hurricane as it bears down on Louisiana

Today's update can be found on the Washington Post's "Capital Weather Gang" blog.  Please stop by there for the latest update on Tropical Storm Isaac.

Elsewhere, there's a sheared disturbance in the middle of the Atlantic (very far from the Cape Verdes, Azores, Lesser Antilles... everything!).  It appears to be close to reaching Tropical Depression status, or if it becomes a tropical storm, the next name on the list is Kirk.
