ATLANTA NEXT, first ever tropical storm warning for city as looting breaks out in Florida

Storm weakening, but still poses threat.

Hurricane Irma has been downgraded to a tropical storm as it moves north towards Georgia. The storm's winds have diminished below 85 MPH, but remain dangerous. The primary concern is now rain, which is causing widespread flooding.

LOS ANGELES, CA (California Network) -- Hurricane Irma is no more, having become a tropical storm this morning. The storm will continue to break up and dissipate as it drops rain across the South. The danger from the storm has not yet passed. Although winds are below 85 MPH, they remain dangerous. Falling trees, debris, and floodwaters still pose a significant risk to life. The storm should remain dangerous until Wednesday when it moves into Western Tennessee as a tropical depression. The Mississippi will see significant inflow from the storm.

The damage in the Caribbean is still being assessed, but some islands were completely destroyed with no buildings left intact. The death toll across the Caribbean was 35 souls, although recovery efforts are ongoing in some areas. It is possible the toll could rise.

In the United States, five fatalities have been reported. It is possible there could be others, as services have not been restored to many areas. Over six million people remain without electricity. The Florida Keys remain cut off from communication.

Footage from the storm also shows water draining from beaches, leaving miles of ocean floor exposed to the air. Hillsboro Bay in Tampa, Florida was also drained of water. Meanwhile, water was pushed on land creating storm surges that flooded urban streets with waist-deep water. Runways at Miami International Airport were flooded.

 About 155,000 people were registered in shelters across the state as of Monday morning.

In the aftermath of the storm, and before the return of effective law enforcement, looting has started. Several viral videos show people stealing electronics and clothing from stores in Irma's wake.

Atlanta has been placed under its first-ever tropical-storm warning.

President Trump has declared Florida to be a disaster area and has signed a declaration that will speed federal funding to the area.

Hurricane Irma may be the most powerful storm ever recorded, although the distinction depends on how one views the data. Irma did not have the highest sustained winds, instead it is tied for second place with four other storms with sustained winds of 185 MPH. Hurricane Allen, from 1980, retains that title with 190 MPH winds. However, Irma sustained its winds at 185 MPH for much longer than any storm in history, 37 hours.
