Ride, Sally Ride! As of the 12:30 PM EDT advisory from the National Hurricane Center has upgraded Sally to a hurricane. Winds are now 90 mph and the satellite shows rapid intensification. It is like spinning a top and this now has good balance to spin faster and gather up more moisture. This is already stronger than the morning models suggested
The forward movement continues to slow down, which will extend the impact along the coast between Florida and New Orleans.
Hurricane and Storm Surge Warnings are already in place. A larger region is now forecast to get 20 inches of rain.
Here is a collection of resources for you to track this storm through landfall and beyond. This includes: Satellite views, live radar, interactive widgets, computer model plots, and National Hurricane Center maps, statements, and warnings.

Computer Model Forecast Plots
Computer Model Forecast Intensity
Sally is already STRONGER than the computer model package from this morning. It could continue to overachieve and reach Category 2 before landfall.
Computer Model Forecast Tracks
The center of the projections is just east of New Orleans. The circulation would maximize the flow from the east to pile water up the Mississippi River and Lake Pontchartrain. After landfall this could get stuck in the south and spin out across the southeast. Most of the rain is now expected to remain well south of the Mid Atlantic region.
