This is what Florida looks like as Irma hits

(CNN)Hurricane Irma's powerful center crossed the Florida Keys and tore into the state's Gulf Coast, downing trees, hurling street signs and debris, and knocking the power out to hundreds of thousands of residents throughout the state.

The National Hurricane Center said Irma is expected to remain powerful as it heads north along the state's Gulf Coast.

    "Anyone who didn't heed the evacuation orders here in Miami Beach, it's time to bunker down," Van Dam said. "It is time to take this storm seriously. Do not come back to the evacuation zones. It has just begun, and it's going to get worse."

    In other parts of the state as of Sunday night, like Tampa, residents had yet to see the worst that Irma could offer.
    Residents in area that had yet to see the worst either evacuated the area or prepared to shelter in place -- including animals in Tampa's Busch Gardens.
    Some residents went out to find Irma had stolen the water away from the beach.
    Facebook user Dylan Branscome shared this video of boats in Charlotte Harbor, north of Naples, sitting on their sides offshore.
    "As the storm approaches from the south, places like Tampa and Port Charlotte are getting strong winds out of the northeast," CNN meteorologist Judson Jones said of the phenomenon. "These winds are strong enough to push the water out of some of the shallow areas of the bays and harbors."

    Jones added that once the wind direction shifts, the water will quickly return.
