A marina owner is boarding up as he plans to ride out the storm

The owner of a marina in Florida's gulf coast town of Steinhatchee told CNN he is choosing to stay put despite local evacuation orders.

“We’re all worried and that’s why we’re staying here -- to see if there’s anything we can do to protect what we have,” Chase Norwood, owner of Chase-N-Fish Charters at Sea Hag Marina, told CNN Tuesday night.

Norwood said the marina is his family's livelihood, leaving him determined to preserve it as much as possible.

They said they have done all they can to prepare for the incoming storm, including boarding up the marina and moving equipment to higher ground. He is hoping floodwaters and storm surge are less severe than expected.

Norwood’s sister, who is pregnant and could give birth any day now, has evacuated the area and gone to Gainesville, he said.

Last year, Norwood helped with storm damage in Fort Meyers after Hurricane Ian hit the area.

“We saw stuff we didn’t know a storm could do and it was an eye-opener,” he said.

A tornado watch is now in effect for more than 7 million people across central and western Florida, including Tampa, until 6:00 a.m. ET Wednesday.

Rain bands from Hurricane Idalia bring the threat for wind gusts of up to 75 mph, marble-sized hail and a few tornadoes overnight as well as into the early morning hours.

Weak and short-lived tornadoes are often associated with the outer bands of landfalling tropical systems.

Evacuees in northern Florida worry for their community's future

From CNN’s Sara Smart

As parts of Florida prepare for the impact of Hurricane Idalia, more residents have stayed than have evacuated in Steinhatchee, an evacuee told CNN.

Lori Leigh Batts-Bennett has already evacuated her condo in Steinhatchee to Jacksonville, Florida and worries for those that stayed behind. Steinhatchee is about 70 miles west of Gainseville.

“Some have that mentality of ‘I’m going to stay here and take care of my own,’” Batts-Bennett told CNN. “Once people wake up they’re going to be paralyzed with what they see.”

The town does not have the infrastructure to handle these storms, Batts-Bennett explained on the brink of tears. She said she and others have started forming plans for how to help tomorrow when it’s safe, mentioning they have people with air boats on standby.

“I fear that if this is catastrophic, the people that make Steinhatchee will not be able to be in Steinhatchee because they won’t be able to rebuild,” she said.

“The landscape of Steinhatchee will be changed forever,” she added.

Some Pinellas County residents say they’re riding out the storm despite evacuation order

From CNN’s Gloria Pazmino and Ila Wilborn in Clearwater Beach

Dave Gentry, a Clearwater Beach resident, was joined by his son and a friend Tuesday evening, hours before the expected landfall of Hurricane Idalia.

“We know the storm is coming a little bit later this evening. We live about 5 miles up the street. We’re going to be here for 20, 30 minutes, watch the waves come in and as the tide comes in, off we go,” Gentry said.

Despite the warnings to evacuate, Gentry said his home is on high ground and that he believes there will be no significant damage to his immediate area. 

Pinellas County has a mandatory evacuation for Zone A and all mobile home residents in effect. The county covers the coastal cities of St. Petersburg and Clearwater.

Clearwater Beach was empty in the early evening except for a few swimmers and a lone surfer, who braved the waves as the wind picked up.

It is approximately 2.5 miles long and sits along the barrier island along the Gulf. Much of the beach is lined with hotel and residential properties.

For hours on Tuesday, hotel workers lined sandbags along the edge of the beach and along the doors to hotel rooms where water could potentially enter. 

Clearwater is forecast to see a storm surge between 4-7 feet. 

Ryan Marc, who lives in nearby Palm Harbor said he’s prepared to ride out the storm in town. 

“Safety first, we don’t want to lose any lives. Things can be replaced, we’ve all been through it at least once in our lives. It is what it is. Nature always wins,” Marc said.

The National Hurricane Center has released its 8 p.m. ET hurricane advisory ahead of Hurricane Idalia's expected touchdown Wednesday in Florida before it churns through Georgia, South Carolina and North Carolina and heads out over the Atlantic.

Click here for the storm tracker.

Here are some of the latest watches and warnings:

  • Englewood northward to Indian Pass, including Tampa Bay is under a storm surge warning, which means that "there is a danger of life-threatening inundation, from rising moving inland from the coastline," according to the advisory.
  • Dry Tortugas, Chokoloskee northward to the middle of Longboat Key, west of Indian Pass to Mexico beach and the Sebastian Inlet in Florida to Surf City North Carolina are under tropical storm warnings, which indicates that "tropical storm conditions are expected," according to the National Hurricane Center.
  • Bonita Beach northward to Englewood, "the mouth" of the St. Mary's River to South Santee River in South Carolina, the Beaufort Inlet to Drum Inlet in North Carolina as well as the Neuse and Pamlico Rivers in North Carolina are under storm surge watches. That means storm surge conditions could be seen over the next 48 hours, the advisory explained.
  • Portions of St. Mary's River to Edisto Beach South Carolina are under a hurricane watch, which means "hurricane conditions are possible within the watch area," the hurricane center says.
  • The Lower Florida Keys west of the west end of the Seven Mile Bridge, north of Surf City North Carolina to the North Carolina and Virginia border as well as Pamlico and Abemarle Sounds are under tropical storm watches. This means tropical storm conditions could be seen within 48 hours, the advisory says.

The National Hurricane Center noted that "additional warnings will likely be required tonight or on Wednesday."

This is Idalia's forecasted path as of 8 p.m. ET.

Tampa General and other area hospitals prepare for Idalia storm surge

Major hospitals in the Tampa and St. Petersburg area are preparing for a significant storm surge from Hurricane Idalia.

Tampa General Hospital – located in the Davis Islands neighborhood in a surge-prone area of the city — has gone as far as to construct a water-impermeable barrier around parts of its campus.

The more than 1,000-bed hospital is expected to be finished assembling the AquaFence barrier — which can withstand up to a 15-foot storm surge — around its vulnerable areas by the end of the day Tuesday, hospital spokesperson Karen Barrera told CNN in an email.

Tampa General will remain open for emergency care and is equipped with a central energy plant that is located 33 feet above sea level and can withstand the impact and flooding of a Category 5 hurricane, housing both electricity generators and boilers for hot water, Barrera said.

Barrera added the hospital has activated its incident command center to keep operating, and as a Level 1 trauma center, Tampa General “stands ready to meet the needs to patients throughout the state who require care after the storm has passed.”

Johns Hopkins All Children's Hospital, a pediatric hospital in St. Petersburg, said it isn’t currently moving any patients, having built a new building in 2010 to withstand hurricane-force winds. 

Most of the hospital’s mechanical areas are on its fourth floor to protect from flooding, and the hospital is capable of having its own potable water and can power itself without being connected to the power grid, if needed, spokesperson Danielle Caci said in an email.

“We are a 259-bed hospital and the largest freestanding pediatric hospital in the area so (we) are prepared to take in patients in need of medical care,” Caci said. 

BayCare, a hospital system that owns 16 acute-care hospitals in the Tampa Bay area, also said it didn't anticipate any "operational changes” other than closing some ambulatory services.

“We have ‘hardened’ our facilities to be as prepared as possible for hurricane season,” said BayCare spokesperson Lisa Razler in an email to CNN, adding the hospitals aren’t moving patients at this time “and we don’t expect that to change.”

Idalia rapidly intensifies and is "likely to become a major hurricane soon," hurricane center says

From CNN’s Caitlin Kaiser and Eric Zerkel

Hurricane Idalia has rapidly intensified over the exceptionally warm waters of the Gulf of Mexico with current maximum winds of 105 mph, according to the 8 p.m. ET update from the National Hurricane Center.

The storm is still a Category 2 hurricane but nearing the Category 3 threshold for wind speeds, which is 111 mph.

Idalia is expected to strengthen more ahead of its landfall in Florida's Big Bend region Wednesday morning.

The National Hurricane Center had warned that rapid intensification was likely in this storm — a phenomenon that is becoming more common as ocean temperatures warm. In order to meet the definition, a storm’s sustained wind speeds must increase by at least 35 mph in 24 hours or less.

The hurricane’s rapid intensification was aided by the Gulf of Mexico’s extremely warm waters. It’s just one of the ways experts say is making hurricanes more dangerous, as warmer waters allow for storms to strengthen quicker.

This is Idalia's forecasted path as of 8 p.m. ET.
