"The tropical depression has strengthened as it approaches the coast and has become tropical storm Imelda, with maximum sustained winds of 40 miles per hour," reads an NHC statement.

"This system is likely to produce flash floods in the northern part of the Texas coast, including Houston and Galveston, which represent a danger to life," the agency said in a message.

The storm has already landed on Freeport, Texas, according to Anthony Ort´íz, a meteorologist at Univision 45. The forecast shows accumulated over 10 inches of rain.

"The slow trajectory that tropical storm Imelda will have will generate a high risk of flooding for Houston," warns Twitter Gastón Heredia, a meteorologist at Ventana al Tiempo.
