As Hurricane Irma raked the Florida Keys on Sunday and moves north, early signs of the storm's power were on display on social media.

David Sutta of CBS Miami shared video on Twitter that showed some of the damage in Key Largo, including a steel sign bent in half. Sutta tweeted that the storm had knocked down signs and trees, but that mobile homes appeared to be intact.

One Twitter user shared video of a power line sparking in Boca Raton, Florida. Another video taken from the St. Petersburg waterfront showed the storm pulling away water from Tampa Bay.

Another appeared to show low water levels from Key Largo.

Irma was downgraded to a Category 2 hurricane with maximum sustained winds of 105 mph after it swept through Naples, Florida, the National Hurricane Center (NHC) said in its latest advisory.

Joey Flechas of The Miami Herald shared video of the storm's powerful gusts in the Brickell neighborhood.

"These winds are punishing and water is rising," he tweeted.
