National Weather Service bulletin for New Orleans region
During an internal assessment by the National Weather Service, the 10:11 bulletin and its impact were examined. The report called the bulletin "a significant moment for the NWS during Katrina," as its detailed and specific language did not have any previous precedent (though the message was based on a template designed by the Tampa Weather Office in 1990). The strongly-worded statement persuaded people to evacuate, and was highlighted by national news media. As a result, the level of detail was highlighted as an "innovative best practice" in the NWS assessment, which recommended issuing warnings with similar levels of detail in the future.
