President Donald Trump is visiting Texas on Friday to assess catastrophic flooding that has killed at least 120 people.

The FEMA Flood Map Service Center offers an interactive map that allows anyone in the U.S. to enter their address and see if they live in a designated flood zone. The tool can also be used to explore other areas, making it helpful for those planning a move, managing a rental property or checking on family or friends in another region.

The risk of the catastrophic flooding that struck Texas Hill Country as people slept on July 4 and left at least 120 dead was potentially underestimated by federal authorities, according to an ABC News analysis of Federal Emergency Management Agency data, satellite imagery and risk modeling.

Forecasters warn that slow-moving storms could bring heavy downpours to already saturated areas, increasing the risk of flash flooding.

President Trump toured the devastation from catastrophic flooding in Texas and lauded local officials amid mounting criticism that they failed to warn residents fast enough that a deadly wall of water was coming their way.

July 9 (Reuters) - U.S. Homeland Security Secretary Kristi Noem called on Wednesday for the Federal Emergency Management Agency to be eliminated in its current form, even as the disaster-relief agency deployed specialists and supplies to Texas to help respond to devastating floods.

Ninety-six of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least 36 children. State officials vowed to continue searching for over 160 people still missing but have acknowledged the dwindling chances of finding survivors alive a week after the disaster.
