What to know about Hurricane Milton as it slams Florida's Gulf Coast

Hurricane Milton slammed into Florida as a Category 3 storm Wednesday, bringing powerful winds, heavy rain and tornadoes to much of the Gulf Coast, including communities already battered by deadly Hurricane Helene.

The hurricane made landfall near Siesta Key, a barrier island of white sand beaches south of the Tampa Bay area, which is home to more than 3.3 million people.

Millions of people were ordered to evacuate. The storm was expected to retain hurricane strength as it crosses central Florida, including the heavily populated Orlando area, on Thursday on a forecast path toward the Atlantic Ocean.

President Joe Biden, who postponed an overseas trip so he could remain at the White House to monitor Milton, said it "could be one of the worst storms in 100 years to hit Florida."

Where and when did Milton make landfall?

Milton made landfall at 8:30 p.m. near Siesta Key, off the coast of Sarasota, about 70 miles (112 kilometers) south of Tampa.

It has about 5,500 residents, many of retirement age.

Florida International University professor Stephen Leatherman, a.k.a. "Dr. Beach," named Siesta Beach the United States' best beach in 2017, and MTV's "Siesta Key" gave audiences a reality-show view of the place in recent years.

How bad is the damage expected to be?

About 125 homes were destroyed before the hurricane made landfall, many of them mobile homes in communities for older adults. More than 1.7 million homes and businesses were without electricity, according to poweroutage.us, which tracks utility reports.

Florida's Gulf Coast is especially vulnerable to storm surge, and Milton was bringing life-threatening high waters to densely populated areas such as Tampa, St. Petersburg, Sarasota and Fort Myers.

Helene came ashore about 180 miles (290 kilometers) north of Tampa and still caused drowning deaths in the Tampa area because of storm surges that were about 5 to 8 feet (1.5 to 2.5 meters) above normal tide levels.

With Milton, forecasters warned of a possible surge of up to 13 feet (4 meters) south of Tampa, from Anna Maria Island to Boca Grande, but downgraded its surge projection in Tampa Bay to 3- to 5-foot (0.9- to 1.5-meter).

Milton was forecast to dump as much as 18 inches (46 centimeters) of rain as it crosses the state, bringing the risk of catastrophic flooding.

Why are scientists saying this is an odd storm season?

Milton is just the latest system in a storm season that scientists say is the weirdest they have ever seen.

Beryl became the earliest storm on record to reach Category 5 status, but there was record quiet from Aug. 20 — the traditional start of peak hurricane season — to Sept. 23, according to Colorado State University hurricane researcher Phil Klotzbach.

Then five hurricanes popped up between Sept. 26 and Oct. 6, which is more than double the old record of two. On Sunday and Monday, there were three hurricanes at the same time, which had never happened before, Klotzback said.

In just 46 1/2 hours, Milton went from forming as a tropical storm with 40 mph winds to a top-of-the-charts Category 5 hurricane.

Some might wonder if it is possible to control extreme weather events. But scientists say hurricanes are too powerful for that, and climate change is providing more fuel than ever for storms like Helene and Milton.

What makes Milton so unusual?

Warm water fueled amazingly rapid intensification that took Milton from a minimal hurricane to a massive Category 5 in less than 10 hours.

Milton also grew so potent because it managed to avoid high-level cross winds that often decapitate storms, especially in autumn. As Milton neared Florida, it hit those winds and dropped in strength.

What if I have travel plans to Florida?

Airports including Tampa International and nearby St. Pete-Clearwater International have shut down.

And the tourism machine in Orlando, about 84 miles (135 kilometers) inland from Tampa, was grinding to a halt. That city's airport — the nation's seventh busiest and Florida's most trafficked — also ceased operations. And at least three major theme parks — Walt Disney World, Universal Orlando and SeaWorld — will close.

What's the connection between hurricanes and the Waffle House?

For some residents of storm-prone Southeastern states, the best indicator of a hurricane's severity can be found at the local Waffle House.

If the Georgia-based restaurant chain stays open in town, neighbors are reassured that the coming storm is unlikely to cause devastation. A closed location of the diner has come to indicate impending disaster.

What might sound like silly logic has become one of the most reliable ways for Southerners and even federal officials to gauge a storm’s severity and identify communities most in need of immediate aid. The Waffle House Index was thought up two decades ago by a federal emergency management official.
