U.S. President Donald Trump said on Monday that federal cash for storm-ravaged areas in Texas, Louisiana, and elsewhere will arrive quickly.

"You're going to have what you need and it's going to go fast," he said, according to The Associated Press, referring to residents of areas suffering from Hurricane Harvey and the resulting flooding.

"We are 100 percent with you. We will get through this. We will come out stronger and believe me we will be bigger, better, stronger than ever before," added Trump, who spoke at a joint press conference with Finnish President Sauli Niinisto.

Harvey, which began as a hurricane before being downgraded to a tropical storm, has dumped historic amounts of rain on areas in and around Houston, which continues to flood.

Trump is expected to travel to Texas on Tuesday to survey storm damage and flooding caused by Harvey.
