Many are questioning why the cranes can't be moved, Miami officials said Tuesday in a tweet.

As Irma approached last week, Miami officials said 20 to 25 construction cranes were up across the city and that they were created to withstand winds of 145 miles per hour (235 kph).

The National Hurricane Center says Category 4 Hurricane Irma is now "headed for the southwest Florida coast" as winds continue to pick up speed in all of South Florida.

Dan Whiteman, vice chairman Coastal Construction, said he has 12 cranes in the Miami area.

There are two dozen such cranes looming over the high-rise city. "Falling cranes kill people", the county said in its suit.

Hurricane Irma has unleashed it's power on Florida, bringing rain and causing widespread flooding, along with gale force winds.

The horizontal arms of some cranes were left loose to spin in the winds.
