Yes, it was tracked even as a tropical wave in the Atlantic for some time, even though nobody was certain where it would hit or how bad it would be. Even as Katrina strengthened rapidly over the Gulf of Mexico was it known quite where the storm would go, though many scientists realized that there was danger for New Orleans.

Hurricanes, including Katrina, can be measured from space by many different types of satellite sensors. These include sensors that passively and actively measure radiation in the visible and infrared parts of the spectrum, among others. Data from the ground are also obtained by ship reports, buoy networks, and any land stations that the storm passes over. The profile of the atmosphere is sampled every 12 hours by weather balloons in areas around the storm. Finally, "Hurricane Hunters" fly into hurricanes to obtain even more data, making many passes through the eye and eyewall and dropping small packets of instruments that remotely transmit information back to the plane. Hurricane Hunters made many missions into Katrina, and this was a well sampled storm.

All of these data are fed into sophisticated, high-resolution tropical forecast models that are run into the future to prediction the track and the strength of the storm. These models performed very well for Katrina due to the excellent data sampling as well as relatively predictable upper air pattern that was steering the storm. Its track was well predicted days in advance, although it veered slightly to the east at the end (which actually helped New Orleans). Strength is more difficult to predict, but using these same models the strength of Katrina was predicted reasonably well in advance, and New Orleans as well as the rest of the Gulf Coast had many days of warning of a powerful hurricane that was nearly imminent.
