Shopping center parking lots in Florida filled with residents preparing for Hurricane Dorian. Even the afternoon rain didn't keep them away.

Outside a supermarket in the Miami suburb of Coconut Grove, all the shopping carts were taken and shelves were starting to empty out.

Reyna Mejia, 27, a stay-at-home mother, was food shopping for the second time in one day.

“I saw the news this morning, and I decided to get moving,” said Mejia, who has a 1-year-old.

During her morning trip, Mejia stocked up on water, baby food and other non-perishables. In the afternoon, she was on the hunt for fruits and vegetables.

“I’m not that worried because we don’t know which way it will go,” she said.

Jen Legil, 33, and her mother, Vicky Legil, 53, were also making their second trip to the supermarket. They were not able to find water in the morning, but another shopper shared five bottles with them.

“Now we’re buying protein bars and anything else that can stay unrefrigerated,” said Legil who is eight- months pregnant and poised to experience her first hurricane after recently moving from New York. “Hopefully it goes another way."

Florida has begun aggressive preparations to brace for Hurricane Dorian, which may intensify into a Category 4 storm by the time it makes landfall, by rolling out disaster plans and telling residents to stockpile supplies.

Gov. Ron DeSantis declared a state of emergency in all 67 counties Thursday because of the storm's "uncertain projected path," and he urged residents to secure at least one week's worth of food, medicine and supplies on hand ahead of the storm.

"All residents, especially those along the east coast, need to be prepared for possible impacts," DeSantis said. "As it increases strength, this storm has the potential to severely damage homes, businesses and buildings, which is why all Floridians should remain vigilant.

"Do not wait until it is too late to make a plan," he added.

Early Friday morning, Dorian remained a Category 2 hurricane with maximum sustained winds nearing 105 mph, but was due to strengthen to become a major hurricane within the day, the center said. It could strengthen to a Category 4 hurricane as it approaches the southeast corner of Florida on Tuesday morning, according to NBC's weather unit.

The government of the Bahamas has issued a Hurricane watch for the northwestern Bahamas and the storm could move near or over the area on Sunday, the National Hurricane Center said in its 5 a.m. advisory Friday.

Several coastal cities have started preparing in anticipation of Dorian's potential fury, including Cape Canaveral, which is in the area where the storm is projected to make landfall.

"We are all in preparation mode," said Todd Morley, a spokesman for the city of Cape Canaveral. Residents have stocked up on necessary items, storm shelters are ready, and all our facilities are strengthened and shuttered, he said.

"We will ride it out in safe places with our loved ones," he said. "We don't know what the damage will be, but we do know how to recover."

Sara Picone, a Cape Canaveral resident, said she is proactively evacuating to ease the minds of out-of-state family.

"Honestly, my family is just really concerned about us, and they're such worrywarts that we're kind of just trying to appease them," she said, adding that the area is "thinning a bit" as others also evacuate.

Cape Canaveral's space ports, including the Kennedy Space Center, Cape Canaveral Air Force Station and Patrick Air Force Base are also prepping.

The Kennedy Space Center canceled visitor hours for Sunday and Monday and has already begun the process of transferring fragile multi-million dollar equipment to secure areas.

The U.S. Navy announced Thursday that it was ordering aircraft at its naval air station in Jacksonville, Florida to start evacuating on Friday.

Many Floridians across the eastern coast saw long lines at gas pumps and empty grocery store shelves as residents frantically rushed to buy supplies like water, canned foods, and batteries.

Outside a Miami Home Depot, that was slightly busier than usual for a Thursday afternoon, Jackie Keenan left Home Depot empty handed. “No water and no flashlights left,” she said.

But Keenan said she was not very concerned. “I have been through it so many times,” adding that she was around for Hurricane Andrew that devastated South Florida in 1992. “If it gets really bad, we’ll leave.”

Several stores said they were already sold out of water and fuel shortages were reported in many counties, according to Gov. DeSantis. He added that supplies would be quickly replenished since the state is under a state of emergency.

Two years ago, Hurricane Irma wreaked havoc on several parts of the Sunshine State, causing mass power outages, extensive flooding, and severe infrastructure damage. Over 120 people died in hurricane-related deaths, according to the CDC.

Much of the state is still trying to rebuild from Irma's devastation, including coastal town Flagler Beach, about 20 miles north of Daytona Beach.

Residents fear Dorian could kick them while they're still down.

"Stay away, stay away, Dorian, we don't need you here," Johnny Lulgjuraj told NBC affiliate WESH in Orlando. He owns a beachside restaurant in Flagler Beach, which was heavily damaged by Irma. "It's just so many things that happened to us in such short period of time."
