President Bush is calling Hurricane Gustav a "serious event."
He's in Texas for briefings on the storm, which came ashore this morning in Louisiana as a Category-2 hurricane.
Bush received an hourlong briefing aboard Air Force One. He's visiting a Texas Emergency Operations Center in Austin and a command center in San Antonio to learn more.
The president canceled a speech to the Republican National Convention tonight because of the hurricane. But Laura Bush has decided to speak as scheduled.
On the morning talk shows today, the first lady said lessons have been learned from Hurricane Katrina. She told CNN that "mistakes were made by everyone" at all levels of government in the handling of Katrina three years ago.
She said communication was poor among local, state and federal officials. But she says "we have taken care of that."
