As of the 5 PM advisory from the National Hurricane Center, Tropical Storm Sally winds still at 60 mph and the forward speed is slowing down. This is a signal of the favorable environment for further growth and longer impact on land.
The warm water and improving conditions will slow down the speed and allow this to possible become a hurricane before landfall. Hurricane and Storm Surge Warnings are already in place. Also, rainfall between 10 to 15 inches near the center are forecast.
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.

The circulation has stacked better with the clouds aloft compared with earlier today. This will allow for further development over the next 12 to 24 hours.

Computer Model Forecast Intensity
Forecast is likely to become a Category 1 hurricane before landfall.
Note the bottom is forecast time.
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, or curve up to the northeast. That would be an issue for the end of next week.
