MIAMI (AP) -- A monster Hurricane Irma roared into Florida with 130 mph winds Sunday for what could be a sustained assault on nearly the entire Sunshine State, submerging streets, knocking out power to millions and snapping massive construction cranes over the Miami skyline.
The 400-mile-wide (640-kilometer-wide) storm blew ashore in the morning in the mostly cleared-out Florida Keys and then began a slow march up the state's west coast. Forecasters said it could hit the heavily populated Tampa-St. Petersburg area early Monday.
"Pray, pray for everybody in Florida," Gov. Rick Scott said on "Fox News Sunday" as some 116,000 people statewide waited it out in shelters.
Irma struck as a Category 4 but by late afternoon had weakened to a Category 2 with 110 mph (177 kph) winds that whipped Florida's palm trees with drenching squalls. A storm surge of over 10 feet (3 meters) was recorded in the Keys, and forecasters warned some places on the mainland could get up to 15 feet of water.
There were no immediate confirmed reports of any deaths in Florida, on top of the 24 people killed during Irma's destructive trek across the Caribbean.
Many streets were flooded in downtown Miami and other cities. Appliances and furniture were seen floating away in the low-lying Keys, though the full extent of Irma's fury there was not clear.
A Miami woman who went into labor was guided through delivery by phone when authorities couldn't reach her in high winds and street flooding. Firefighters later took her to the hospital.
An apparent tornado spun off by Irma destroyed six mobile homes in Palm Bay, hundreds of miles away along the state's Atlantic coast. Flooding was reported along Interstate 4, which cuts across Florida's midsection.
In downtown Miami, two of the two dozen construction cranes looming over the skyline collapsed in the wind. No injuries were reported. City officials said it would have taken about two weeks to move the massive equipment.
Curfews were imposed in Miami, Tampa, Fort Lauderdale and much of the rest of South Florida, and some arrests of violators were reported. Miami Beach barred outsiders from the island.
