(CNN)As Hurricane Harvey barrels toward the Texas coast, the Houston metropolitan area, prone to flooding and home to more than 5 million people, is bracing for the potentially devastating storm.
Houston's school system has already canceled classes on Monday, the first day of classes. The city's parks and main zoo are closed.
The Houston Dynamo, the city's Major League Soccer team, canceled this weekend's games and Coldplay nixed its Friday night concert, all in preparation for Harvey, which was expected to make landfall by early Saturday.
Houston's main concern is the risk of flooding. In May, the city was hit by heavy flooding when 240 billion gallons of rain fell on the city. That claimed eight lives, flooded more than 1,000 homes and caused more than $5 billion in damage, according to officials.
Now the city is staring down Harvey, which Brock Long, director of the Federal Emergency Management Agency, called "the first major hurricane the nation has dealt with since 2005."
