As Hurrican Isaac slapped New Orleans this week, powerful computers were able to give the city detailed data on possible threats.
 
This story from Patrick Thibodeau of Computerworld U.S. notes the computers now available from Louisiana State University are significantly more powerful than the ones that were available seven years ago when Hurricane Katrina struck.

According to Wikipedia, computer simulations for weather date back to the 1950s and even then needed the most powerful processors available. Even still, it’s more an art than a science because weather, by its nature, can be unpredictable. Still, forecasts are getting increasingly accurate.
 
This story notes that the data helps emergency planners predict what roads will flood, allowing them to position supplies for recovery.
 
When Katrina struck computer modelling was available, the story makes clear, but not as detailed as it is today.
