A tropical depression has formed in the Gulf of Mexico, off the Texas coast and is expected to bring heavy rainfall and flooding across coastal areas, including Houston, according to the National Hurricane Center.
The depression is the 11th formed system this season and brings with it the probability of tropical storm force winds exceeding 39 mph , according to the National Hurricane Center.
The Harris County Flood Control District said its monitoring a tropical disturbance currently over the Western Gulf of Mexico, which is expected to drift inland Tuesday and into Wednesday creating thunderstorms for much of the week.

The disturbance is expected to bring heavy rains and potential street flooding to much of the Houston area Tuesday in what is expected to become a week filled with rainfall, meteorologists say.
The National Weather Service has issued a Flash Flood Watch for Harris, Galveston, Chambers, Liberty, Brazoria, Matagorda and Fort Bend counties starting at 1 p.m. Tuesday and through 1 p.m. Wednesday, Sept. 18. That watch could be extended into Wednesday night as the storm system unfolds.

The watch includes much of coastal southeast Texas, as well as Galveston Island and Bolivar Peninsula.
Parts of the Houston area experienced substantial rainfall Tuesday morning, including nearly 2 inches of rain in southeast Harris County from midnight to 6 a.m. Heavy rain is likely Tuesday in nearly all of the counties that will be under the Flash Flood Watch, and even southern Montgomery County, the weather service says.
Some areas will receive up to 3 inches of rain by Wednesday morning, with some areas receiving 4 to 6 inches of rain. Another 2 to 4 inches is expected into Wednesday night.
One benefit of the storm system: Houston’s temperatures will peak in the mid-80s for the next few days.
