This is the destruction Irma left behind in Florida

Hurricane Irma weakened as it pummeled Florida — but the storm still packed a powerful punch, spawning torrential downpours, tornadoes and flash floods.

First Irma slammed into the Florida Keys Sunday morning as a Category 4 hurricane, ripping roofs off of mobile homes and littering roads with debris. A day later, it had weakened to a tropical storm, but still brought dangerous storm surge flooding to Jacksonville.

Here’s a look at some of the destruction Irma left in her wake. Authorities are still surveying damage from the record-breaking storm, and this story will be updated as more details emerge.

KEY LARGO

The Florida Keys took a direct hit from Irma at one of the storm’s most powerful points. About 5,000 of the Keys’ 30,000 permanent residents stayed to ride out the storm, Florida Keys spokesman Andy Newman said.

Roofs ripped off: CNN’s team in Key Largo saw some areas devastated by the storm, with roofs ripped off mobile homes in one neighborhood. In other parts of the island chain, the closure of US 1, a major artery that connects the islands with the mainland, was a prime concern. “There does not appear to be major structural damage,” Newman said. “It’s the road. It’s being able to get supplies down.”

In the dark: According to state officials, more than 50,000 customers are without power in Monroe County, Florida, which includes the Keys. “We have no cell service, no electricity, and no water,” Monroe County Commissioner Heather Carruthers said.

MIAMI

Gusts topping 90 mph whipped Miami on Sunday, knocking out power to most of the city’s residents. Streets flooded, and flying objects such as coconuts turned into dangerous projectiles. At least two construction cranes partially collapsed.

Clearing roads: The main concern is the roads, Miami Mayor Tomas Regalado said, as thousands of trees are down.

In the dark: Most of the city (72%) is without power, the mayor said Monday.

MARCO ISLAND

This southwest Florida city was the second place Hurricane Irma made landfall, striking Sunday afternoon as a Category 3 storm.

Storm surge: Large portions of Marco Island were flooded by a 3- to 4-foot storm surge, said Chris Bowden, spokesman for the Marco Island Fire Department.

Downed power lines: There are many power lines down, Bowden said, and the main power pole off the island also went down in the storm. About 2,000 customers there are still without power.

NAPLES

Naples was pummeled by Hurricane Irma on September 10 — coincidentally the same day that Hurricane Donna devastated the city 57 years ago. But this time, Naples seems to have fared better, according to David Fralick, the city’s communications manager.

Like a war zone: “It looks like a war zone, but it’s still pretty good,” Fralick said. “The storm surge could have been a whole lot worse.”

Widespread power outages: Most of the city doesn’t have power, Fralick said.

TAMPA

The Tampa Bay area feared a direct hit from a major hurricane, but ended up getting more of a sideways swipe from a weakened Irma.

Homes destroyed: About a dozen homes were hit by trees and destroyed in Hillsborough County, where Tampa is located, according to an initial assessment by county officials.

Not over yet: Residents near rivers will start to see flooding as the days go on, Hillsborough County Administrator Mike Merrill said.

JACKSONVILLE

While some coastal communities breathed a sigh of relief, people in Jacksonville, Florida, faced flash flooding on Monday. The St. Johns River rose to record levels, flooding major roadways.

Flash flood emergency: The National Weather Service issued a flash flood emergency for parts of downtown Jacksonville.
