Irma's strong winds spread across Florida
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.
Irma continues to be armed with 130 mph winds as its large eye passes north of the Keys.
Storm surge is forecast for 10 to 15 feet in southwestern Florida.
Hurricane-force winds are continuing throughout southern Florida, including the Keys. The hurricane center warns that winds affecting upper floors of high-rise building will be much stronger than at ground level.
The hurricane center also emphasizes that Irma will bring life-threatening wind to much of Florida regardless of the exact track of its center.
Puerto Rico's governor says there will be no classes on Monday because hundreds of schools still do not have power or water after the island took a hit from Hurricane Irma.
Ricardo Rossello said Sunday that more than 600 schools don't have power and more than 400 don't have water. Another nearly 400 schools don't have either, and dozens are flooded.
Nearly 600,000 people in the U.S. territory remain without power, representing 40 percent of customers of the Puerto Rico Electric Power Authority.
The National Weather Service says that a crane has collapsed in Miami as strong wind from Hurricane Irma blows in.
It's one of two-dozen in the city.
The weather service's Miami office said in a Tweet that one of its employees witnessed the crane boom and counterweight collapse in downtown Miami. The employee captured video of the collapse.
It wasn't immediately clear if the collapse caused damage or injuries.
The cranes have been a concern.
Construction sites across Irma's potential path in Florida were locked down to remove or secure building materials, tools and debris that could be flung by Irma's winds.
But the horizontal arms of the tall tower cranes remained loose despite the potential danger of collapse. According to city officials, it would have taken about two weeks to move the cranes and there wasn't enough time.
Hurricane Irma's large eye is beginning to move slowly away from the Florida Keys as it continues north with 130 mph (215 kph) winds.
The U.S. National Hurricane Center in Miami reported that the center of core of Irma is about 25 miles (40 km) northeast of Key West.
Irma is so wide that a gust of 93 mph (150 kph) was measured near Key Largo at the other end of the Florida Keys.
