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.

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

President Donald Trump was expected to arrive in Kerr County, Texas, Friday afternoon, one week after the area was struck by catastrophic flooding.

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.

On Thursday, the Texas House and Senate announced the creation of committees on disaster preparedness and flooding.

President Donald Trump is traveling to central Texas on Friday to survey the aftermath of a catastrophic flood that has killed more than 100 people and put his administration on the sudden defensive over its emergency response efforts.
