HOUSTON - More rain is likely as Houston cleans up after more than a foot of rain swamped parts of the nation's fourth-largest city.

The National Weather Service says there is a 50 percent chance of more rain falling on the Houston area Tuesday and has issued a flash flood watch through Wednesday morning.

Houston Mayor Sylvester Turner says the city is returning to normal operations and advises drivers to take care on flooded roads.

Five people died in the Houston area after storms since Sunday dumped up to 16 inches of rain. Dozens of schools, public transit and city offices were closed Monday.

The Metropolitan Transit Authority resumed service Tuesday, including light-rail operations.

A chance of showers continues through Thursday.
