President Trump on Friday warned Americans in the path of Hurricane Irma of the "historic, destructive potential" of the category 4 storm and encouraged those in its path to listen to emergency responders and local officials.

"This is a storm of absolutely historic, destructive potential," Trump said during his weekly address Friday. "I ask everyone in the storm's path to be vigilant and to heed all recommendations from government officials and law enforcement. Nothing is more important than the safety and security of our people."

Hurricane Irma tore through the Caribbean earlier this week, and devastated the U.S. Virgin Islands and Puerto Rico. The storm is now heading toward Florida and is expected to make landfall late Saturday night into Sunday morning.

A hurricane warning has been issued for South Florida, and it's expected to spread north as the storm moves toward the state. Evacuation orders have been issued for the Florida Keys and coastal areas of Florida.

In his weekly address, the president reassured those in Hurricane Irma's path the federal government is working to prepare for the storm, and said he is confident Americans will come together once the hurricane passes.

"From Texas to Louisiana, from Florida to Puerto Rico, and always the U.S. Virgin Islands and everywhere in between that has been affected by these terrible storms, we will endure and come back stronger than ever before," Trump said.

After addressing Hurricane Irma, the president pivoted to tax reform, making his pitch to the American people as Republicans in Congress continue to negotiate a plan to overhaul the tax code.

"This is our chance to give American workers a level playing field, to end the rigged system that lets special interests win at the expense of the middle class, and to re-establish our economic dominance for generations to come," Trump said.

The president outlined his four principles for tax reform — simplify the tax code, cut taxes for middle-class families, lower tax rates to make businesses more competitive, and encourage companies to bring money back to the US — and said his goal is to help create jobs and raise wages.

"My administration is working closely with Congress to develop a plan that will deliver more jobs, higher pay, and lower taxes for businesses of all sizes, and most importantly for middle-class families all across America," he said.

Trump has started to take his tax reform pitch on the road, speaking at events in Bismarck, N.D., on Wednesday, and Springfield, Mo., last week.
