(CNN) — Floridians along the Atlantic coast were coping Friday with rising water as Hurricane Matthew drenched the state with rain and strong winds pushed waves over beaches.
Meteorologists said storm surge had been measured at more than 4 feet in some areas.
The storm, which is blamed for four deaths in Florida, sparked flash-flood concerns. The National Weather Service issued a warning for parts of Nassau County, north of Jacksonville.
“The combination of a dangerous storm surge, the tide and large and destructive waves will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline,” the National Hurricane Center said.
After killing hundreds in Haiti and other Caribbean nations, Matthew’s frightening power led to the deaths of four people in Florida. The list included a woman in her 60s in Volusia County (by a falling tree) and an 82-year-old man and a woman in St. Lucie County, officials said. The latter two had medical emergencies and responders were unable to reach them in time because of hazardous weather.
A woman in northeast Florida died after a tree fell on her camper trailer, the Putnam County Sheriff’s Office said.
The Category 2 hurricane, while losing some of its wind speed, has left more than 1 million people without power as it skirts the state’s east coast, with the most damaging blow possibly still to come.
“We are seeing impacts right now from St. Augustine to Jacksonville Beach. Unfortunately, this is going to continue through the night,” Gov. Rick Scott said.
Governors in North and South Carolina warned residents to get out in advance of the storm, which could drop as much as 15 inches of rain.
But it’s not as if Matthew — with winds of 110 mph at the center — didn’t cause any damage with its powerful winds.
Parts of St. Augustine flooded even as the hurricane was still approaching. A virtual river of water rushed past a bed and breakfast business in the city about 35 miles southeast of Jacksonville, according to video posted by reporter Russell Colburn of CNN affiliate WJAX.
Special concern surrounded Jacksonville’s St. Johns River, which could be overwhelmed by water pushed into it by the storm. The hurricane center said a tide gauge reported storm surge of 4.28 feet.
“Just because the center of circulation is offshore doesn’t mean you can’t be the center of action (along the coast),” National Hurricane Center Director Rick Knabb said. “It’s going to get a lot worse before it (has) a chance of getting better.”
Here’s what you need to know:
• As of 7 p.m. ET, Matthew’s center was over the Atlantic, about 50 miles east-northeast of Jacksonville Beach, the National Hurricane Center said. Hurricane-force winds extended outward up to 60 miles from that center. It was moving north at 12 mph.
• Jacksonville could see storm surges of up to 9 feet Friday afternoon, forecasters said. Anything over 3 feet in the city is life-threatening, Mayor Lenny Curry said.
• “Very dangerous conditions, and it’s going to get worse into the afternoon,” Curry said.
• A total of 1.1 million customers statewide were without power.
• Forecasters predict storm surges in coastal Georgia and South Carolina also could be as high as 9 feet, and as many as 15 inches of rain could fall from central Florida to North Carolina.
• The National Weather Service warned that some places hit by Matthew could be uninhabitable for “weeks or months.”
• The storm has killed at least 300 people in three Caribbean countries. The majority died in Haiti, said Civil Protection Service spokesman Joseph Edgard Celestin.
Though the storm hasn’t made landfall, it left swaths of coastal Florida with downed trees and power lines.
Matthew kicked up debris and street flooding in Daytona Beach late Friday morning. Video recorded by journalist Robert Ray showed metallic, foil-like debris and other small objects rolling down one of the streets in the city.
Scott said officials are particularly concerned about low-lying areas in and around Jacksonville, where there is potential for significant flooding.
Major southern Florida population centers such as Miami and West Palm Beach appeared to have avoided the worst of the storm, as the dangerous eyewall stayed about 100 miles off the coast.
Georgia, South Carolina and North Carolina
As northeastern Florida braced for impact, coastal communities in Georgia, South Carolina and North Carolina also were on notice. The storm’s center could be near or over the coasts of Georgia and South Carolina on Saturday, the hurricane center said.
• Glynn County officials wrote on Facebook that “Conditions have deteriorated to a point that persons remaining in (the area near Brunswick) are advised to shelter in place for the remainder of the storm.”
• Maj. Tommy Tillman of the Chatham County Sheriff’s Office said the road to Tybee Island is closed.
• In Savannah, Mayor Eddie DeLoach warned those who stay that they’d be on their own.
• Gov. Nathan Deal has ordered evacuations for all counties east of Interstate 95. Deal has activated 1,000 National Guard troops.
• Four counties and one city in South Carolina will be under nighttime curfews until further notice, said state Emergency Management Division spokesman Derrec Becker. Dorchester, Beaufort, Jasper and Williamsburg counties will be under curfew. Charleston’s curfew starts at midnight. The curfews end each morning, at different times.
• Gov. Nikki Haley warned residents who didn’t evacuate to go to a shelter. A major storm surge of 8 feet or more is approaching low-lying areas in the state, including Charleston.
• Although 310,000 people have evacuated the area, Haley says that’s not enough. Officials in some areas are going door to door, urging people to leave. Police in Pawleys Island asked residents who decided to stay in spite of the evacuation orders to sign a waiver and list their next of kin, according to CNN affiliate WBTW.
• Gov. Pat McCrory said the forecast had change, to North Carolina’s detriment. “What we feared is now happening in North Carolina. The (hurricane forecast) model has changed dramatically,” he said. “The immediate concern is life-threatening rain and water (from storm surge).”
• Officials are concerned that eastern areas — like Fayetteville, home to a large Army base — that were recently flooded will see more rain from Matthew.
