Organizers estimate more than 2,000 people attended Saturday's event, making it the largest event of its kind in the country.

Houston and hurricanes have a history, but recent years have shown us the city doesn't need a hurricane or even a tropical storm for widespread and destructive flooding. That's why the City of Houston's Office of Emergency Management teams up with local agencies and media. They start planning the expo a year in advance to make sure we all know what to do if a weather emergency hits.

"A lot of folks in Houston were not here in 2008, the last time we had a hurricane," said City of Houston Office of Emergency Management spokesman Michael Walter. "That means a lot of people don't know what to do. We're really encouraging people to have a plan, make a kit, get informed, know your neighbors."
