Hurricane Irma roared through the Florida Keys with punishing winds Sunday and began pushing its way north, flooding streets, spawning tornadoes, knocking out power to more than 3 million people across the state and snapping massive construction cranes over the Miami skyline.
The National Hurricane Center (NHC) said in its 11 p.m. advisory that Irma would continue moving north over the western Florida peninsula through Monday morning and then into the southeastern United States late Monday and Tuesday.
The nearly 400-mile-wide storm, still a Category 2 hurricane, was expected to make a slow, ruinous march up Florida's west coast, straight toward the heavily populated Tampa-St. Petersburg area by Monday morning. At 11 p.m. Eastern the storm was about 50 miles southeast of Tampa, moving toward the city at about 14 mph.
Streets had emptied across the bottom half of the Florida peninsula, and some 127,000 people were huddled in shelters.
Late Sunday afternoon, Irma made landfall on Marco Island as a Category 3 storm. The NHC in Miami said Irma's powerful eye roared ashore at Marco Island just south of Naples with 115 mph winds, for a second U.S. landfall at 3:35 p.m. Sunday. Category 3 storms have winds from 111 to 129 mph, but a 130-mph wind gust was recently reported by the Marco Island Police Department.
There were no confirmed deaths blamed on the storm in the U.S. as of late Sunday evening. The storm left at least 27 people dead as it tore across the Caribbean.
"I know the winds are going to be very devastating and life threatening. But I'm also very concerned about the storm surge," Gov. Rick Scott said on "Face the Nation."
While the projected track showed Irma raking the state's Gulf Coast, forecasters warned that the entire state -- including the Miami metropolitan area of 6 million people -- was in extreme peril because of the sheer size of the storm.
Nearly 7 million people in the Southeast were warned to evacuate, including 6.4 million in Florida alone.

11 p.m.: Hurricane Irma nears Tampa as Category 2 storm
Hurricane Irma remains a dangerous Category 2 hurricane despite weakening a bit more to 100 mph. It's now bearing down on the Tampa-St. Petersburg region.
NHC released its latest advisory to report that Irma's eye is about 50 miles southeast of Tampa and moving at a fast clip of 14 mph. Still a large hurricane, its tropical storm force winds extend out 415 miles.
Hurricane Irma's forecasted path as seen from the National Hurricane Center's latest 11 p.m. advisory on Sun., Sept. 10, 2017.
Forecasters say they expert Irma's center to stay inland over Florida and then move into Georgia, Alabama and Tennessee.
They also expect Irma to weaken further into a tropical storm over far northern Florida or southern Georgia on Monday as it speeds up its forward motion. The hurricane center says the storm is still life-threatening with dangerous storm surge, wind and heavy rains.
10:52 p.m.: University of Tampa students hunker down in dorms
CBS News correspondent Don Champion spoke with students from the University of Tampa who decided to stay in their dormitories throughout Hurricane Irma because the facilities were rated for Category 5 storms and they felt very safe.
Gusts have been reported up to 50 mph and officials are expecting a storm surge for up to 6 feet. This is a city that is very flood prone so city officials are warning folks that the threat from Irma is far from over, Champion reports.
10:25 p.m.: 3rd construction crane falls to Irma's winds
A third construction crane has toppled in Florida in the powerful winds of Hurricane Irma.
Officials say it happened at a project on Fort Lauderdale beach during the storm Sunday.

Miami International Airport will be closed Monday after sustaining "significant water damage" on Sunday from Hurricane Irma's powerful gusts of nearly 100 mph, Miami-Dade Aviation Director Emilio González announced on Twitter.
The airport expects to begin operations with limited schedules on Tuesday.
More than 3.3 million homes and businesses have lost power in Florida as Hurricane Irma moves up the peninsula. The widespread outages stretch from the Florida Keys all the way into central Florida.
Florida Power & Light, the state's largest electric utility, said there were nearly 1 million customers without power in Miami-Dade County alone. The power outages are expected to increase as the storm edges further north.
There are nearly 7 million residential customers in the state.

8:26 p.m.: Manatees rescued after low tide in Sarasota Bay
Hurricane Irma pulled water from Sarasota Bay on Sunday afternoon and left several manatees stuck in knee-deep mud,.
A few residents in the area came to the rescue, placing them on large green tarp and pulling them more than 100 yards back into the water.
After becoming restless, Marcelo Clavejo checked out the bay near Whitfield where he noticed the manatees on the flats. "So we went for a ride and ended up saving two manatees," Clavejo posted on Facebook.
Florida residents rescue manatees stranded by a low tide.
8:15 p.m.: Irma moves toward Fort Myers
The National Hurricane Center said in its 8 p.m. advisory that Hurricane Irma is moving northward near Fort Myers and that dangerous storm surges are expected in areas of onshore winds along the Florida west coast. Irma was 15 miles east-northeast of Fort Myers and about 30 miles southeast of Port Charlotte.
Maximum sustained winds have decreased to 105 mph, according to NHC and is moving north at about 14 mph.
Irma's eye should move near or over the west coast of the Florida Peninsula through Monday morning, the center says. Irma should the move inland over northern Florida and southwestern Georgia on Monday afternoon.
Irma is expected to remain a hurricane through Monday morning -- and that hurricane-force winds extend outward up to 80 miles from the center -- and tropical-storm-force winds extend outward up to 220 miles.
7:26 p.m.: Roof leaks as thousands shelter in Germain Arena
The Lee County Sheriff's Office says water began leaking through the roof at the Germain Arena shelter in Estero just as the eye of Hurricane Irma drew near.
Thousands of evacuees have crowded into the minor-league hockey stadium, which seats about 8,400 people and is being used as a shelter.
The sheriff's office said on Facebook that authorities are monitoring the problem and that the facility is stable.
In this photo taken on Sat., Sept. 9, 2017, evacuees stand in line to enter the Germain Arena, which is being used as a fallout shelter in Estero, Fla.
7:20 p.m.: Miami-Dade schools to remain closed
Miami-Dade County Public Schools will remain closed until further notice, Superintendent Alberto Carvalho announced late Sunday.

Earlier Sunday, Carvalho said further announcements would be made regarding "shelter closures, school site inspections and workforce readiness."
7:00 p.m.: Storm surge could damage 455,000 Tampa Bay homes
Hurricane Irma should be moving directly over the Tampa Bay area around 12 a.m. on Monday. Residents of the highly populated area are fearing the worst.
A report by CoreLogic, the global property data firm, found nearly 455,000 Tampa Bay homes could be damaged by storm surges, the most of any major U.S. metro area other than Miami and New York. Rebuilding those homes could cost $81 billion.
Tampa Bay is vulnerable because the bay acts as a funnel for storm surges, forcing water into narrow channels with nowhere else to go.
6:36 p.m.: Water levels rise in Naples
Water levels are rising rapidly in Naples, Florida, from Hurricane Irma's storm surge, the National Hurricane Center said Sunday evening. A federal tide gauge in Naples reported a 7 foot rise of water in just 90 minutes.
A wind gust of 142 mph was recorded at the Naples Municipal Airport as the storm kept its top sustained wind speed of 110 mph.
Irma has picked up forward speed and is moving inland at 14 mph and its eye is about 25 miles south southeast of Fort Myers.

The federal government will also reimburse counties for emergency protective measures -- including evacuation and sheltering costs and much of the costs for debris removal.
5:15 p.m.: Irma approaches Naples, Florida, as Category 2 storm
The NHC said in its 5 p.m. advisory that Hurricane Irma is about 5 miles north of Naples, Florida, and about 30 miles south-southeast of Ft. Myers, Florida. The storm has maximum sustained winds near 110 mph, the center said.
Irma is moving toward the north near 14 mph and a north-northwestward motion with an increase in forward speed is expected by tonight, with that motion continuing through Monday.

1 p.m.: Irma's winds impede access to toppled crane site
A crane atop a high-rise under construction in downtown Miami collapsed Sun., Sept. 10, 2017, amid strong winds from Hurricane Irma.
High winds are impeding Miami authorities' ability to reach a construction crane toppled by Hurricane Irma. The crane fell onto a high-rise building that's under construction. It's in a bayfront area filled with hotels and high-rise condo and office buildings, near AmericanAirlines Arena.
Miami-Dade County Director of Communications Mike Hernandez said emergency personnel couldn't immediately respond to the scene because of high winds. Authorities urged people to avoid the area after the Sunday morning collapse. It wasn't clear if there were any injuries.
Miami City Manager Daniel Alfonso said the approximately two-dozen other cranes in the city are still upright and built to withstand significant wind gusts. The tower cranes working on construction sites throughout the city were a concern ahead of Irma. Moving the massive equipment, weighing up to 30,000 pounds, is a slow process that would have taken about two weeks, according to city officials.
12:30 p.m. Florida senator: Irma has potential to be "worst-case scenario"
Sen. Marco Rubio, R-Florida, said Sunday that for those living in Naples, Fort Myers, Sarasota and the Tampa Bay region, Hurricane Irma has the potential to be the "sort of worst-case scenario that meteorologists and emergency planners dread."

9:30 a.m.: Irma makes landfall
Hurricane Irma has made landfall on Cudjoe Key in the lower Florida Keys. The U.S. National Hurricane Center in Miami said the storm's center made landfall at 9:10 a.m. Its top sustained winds are 130 mph.
8:15 a.m.: Hurricane Irma's center poised to blow across Florida Keys, forecasters say
The U.S. National Hurricane Center said in a public advisory that the center of the storm remained offshore but was going to make landfall soon. The storm was centered about 20 miles east of Key West, and it was moving north-northwest at 8 mph.
The storm had maximum sustained winds of 130 mph. The National Weather Service reported wind gusts of 90 mph near its Key West office. After hitting the Florida Keys, Irma was forecast to move up the state's Gulf Coast later Sunday.
8:05 a.m.: Tornado warnings issued
The National Weather Service in Miami has issued tornado warnings for a wide swath of Monroe, Miami-Dade and Broward counties in South Florida.
Officials say the band of rain and tornado producing cells is moving quickly. There have been no reports of tornadoes touching down.
Authorities are urging people to stay inside until the storm passes.
"Due to extreme sustained winds rescue teams are no longer able to respond. Stay inside and Stay safe until the storm has passed," the City of Miami Beach tweeted.
In a Facebook post early Sunday, Key West Police urged people who stayed for the hurricane to remain where they took shelter until the storm had passed completely. They also urged people not to go outside when the eye of the storm is over there area, a time period when conditions can seem deceptively calm.
6:55 a.m.: St. Petersburg now in Irma's crosshairs
With Hurricane Irma churning toward the Florida Key's and the southernmost tip of the mainland on Sunday morning, Florida Power & Light said more than 250,000 homes and businesses were already without power by 6:30 a.m. in Miami-Dade county -- an hour before the storm was even expected to make landfall. Another 97,370 outages were reported in Broward.
The outages were blamed largely on high winds snapping power lines and taking out transformers.
12:40 a.m., Sept. 10: National Hurricane Center tweaks forecast
The National Hurricane Center's latest tweak to Irma's forecasted track has the storm hugging the Florida's west coast off Fort Myers, but possibly not making landfall there before moving back to the Gulf of Mexico. By moving the likely track a few crucial miles west, the storm would be able to regain strength over water before its deadliest winds hit St. Petersburg and Clearwater, rather than the more populated Tampa.
After that, the storm is now expected to skirt the coast again a bit north of Horseshoe Beach, then finally go inland around Fish Creek, northwest of Ocala, with a hurricane-force wind field well over 100 miles wide.
Irma's forward motion slowed to 6 mph as the storm stuttered off the coast of Cuba. Forecasters say it could still increase in strength, but their forecast didn't show it.
11:55 p.m.: South Florida county pulls deputies off roads
The Broward County sheriff's office tweeted late Saturday that with wind gusts measuring 45 mph, they are pulling deputies off the road until conditions are safer.
11 p.m.: Irma is taking its time leaving Cuba
Hurricane Irma is moving slowly away from the north coast of Cuba as hurricane-force winds were recorded in the Florida Keys, the National Hurricane Center said.
A turn toward the north-northwest with an increase in forward speed is expected through late Monday. The center of Irma is expected to pass through the Keys Sunday morning and then move near or along the west coast of Florida Sunday afternoon through Monday morning. Irma should then move inland over the Florida panhandle and southwestern Georgia Monday afternoon.
Dangerous storm surges are expected in Florida, with surges of 10 to 15 feet from Cape Sable to Captiva.
More than 170,000 homes and businesses in Florida are without power, Florida Power and Light said. More than half the outages are in the Miami-Dade area.
