Rainfall associated with Hurricane Irma nearly covered the entirety of the state of Florida in the early evening Sunday.

As of 5 p.m. Eastern, the National Hurricane Center reported that the hurricane is weakening as it has made two landfalls over the Florida Keys and Marco Island since the morning.

However, the storm remains a dangerous "major" Category 3 hurricane. The eye is forecast to head toward the Tampa Bay area and later Tallahassee before reaching Alabama and Georgia, but the extent of the rain from Irma stretches from across the state, east to west, from tip to top, according to radar imagery from the National Weather Service. Only the far western portions of the panhandle appeared to be without rain.

Up to 10 to 15 inches is expected in some parts of the Western Florida peninsula, with isolated areas of 20 inches, according to NHC.

"Irma is expected to bring heavy rainfall and flooding to much of Florida and portions of the southeast U.S. over the next few days," NHC tweeted.

"Life-threatening" storm surge and also remains an issue through much of the Sunshine State.

The evacuations of millions have been ordered across the state and officials have scrambled to fit as many people as possible in shelters.

President Trump, who has been briefed daily this weekend on Irma, made a major disaster declaration for Florida, ordering federal aid "to supplement State, tribal, and local recovery efforts in the areas affected by Hurricane Irma beginning on September 4, 2017, and continuing."

"The bad news is that this is some big monster, but I think we're very well coordinated," Trump told reporters on the South Lawn of the White House, flanked by his wife Melania, on Sunday just before the declaration was made. He also said he would be visiting Florida "very soon."

At least three people in Florida have died in connection to Irma, including a sheriff's deputy, according to ABC News.
