Hurricane Isaias’ track shifts closer to Florida coast - WJXT News4JAX

Hurricane Isaias lashed the southeastern Bahamas and the Turks and Caicos Islands with strong winds and heavy squalls Friday morning and hurricane conditions were expected to continue over parts of the Bahamas during the day.

The National Hurricane Center said early Friday that Isaias was predicted to intensify into a Category 2 hurricane over the Bahamas Friday night, but later in the morning revised that, saying it would remain Category 1, but come slightly closer to Florida’s East Coast.

At 11 a.m., Isaias had maximum sustained winds of 75 mph with gusts up to 90 mph. The storm is moving fast to the northwest at 16 mph. Isaias is currently 295 miles southeast of Nassau. The minimum central pressure remained at 992 mb.

A general northwestward motion with some decrease in forward speed is expected for the next couple of days followed by a turn toward the north-northeast, the NHC said.

Hurricane Warnings were in effect for the northwestern, southeastern and Central Bahamas and a Hurricane Watch was issued between Deerfield Beach and the Brevard-Volusia County line. A Tropical Storm Warning is in effect from Ocean Reef northward to Sebastian Inlet and for Lake Okeechobee.

The center of the storm could brush the coast of Florida near Sebastian.

On the forecast track, the center of Isaias will move near or over the southeastern Bahamas today. Isaias is forecast to be near the central Bahamas tonight, and move near or over the Northwestern Bahamas and be near or east of the Florida peninsula early Sunday morning

If Isaias follows the predicted track, impacts on the Northeast Florida area would be minimal, with rough surf, a high risk for rip currents and coastal rain.

Chief Meteorologist John Gaughan said he was surprised by the National Hurricane Center’s rare midnight update that upgraded Isaias to a hurricane despite what appears to be the lack of a classic “eye wall” inside the storm.

“I was looking at the Hurricane Hunter reports just after the 11 p.m. news and saw that they had measured hurricane-force winds and a teeny tiny calm spot. It took the Hurricane Hunter aircraft all of 90 seconds to pass through it,” Gaughan said. “In other words, there seemed to be an ‘eye’ but without the classic ‘eye wall’ structure... (which) includes a ring of thunderstorms, surrounding a calm spot.”

Gaughan said the 2 a.m. update from NHC followed a two center pass through the storm by the Hurricane Hunter and there does appear to barely be an eye but it is confined to a 4-mile wide area of light winds that are not surrounded by higher winds (eye wall).

“Plus, satellite images show warming (weakening storms), strongly hinting that whatever it was, it is fading now,” Gaughan said.

He said this likely changes little for our area.

“This very small storm will likely fluctuate in intensity the next number of days,” he said.

Storm hits Puerto Rico and the Dominican Republic

Tropical Storm Isaias knocked out power and caused flooding and small landslides across Puerto Rico and the Dominican Republic on Thursday, then strengthened into a hurricane late in the night while moving toward the Bahamas and U.S. East Coast.

The storm's rain turned several streets into fast-flowing rivers and toppled trees and some telephone and electrical cables in Puerto Rico, which is still recovering from previous hurricanes and earthquakes. The National Guard rescued at least 35 people, including two newborns. Authorities in the northwest town of Rincon reported a woman missing after floodwaters swept her away when she tried to drive across a bridge.

Government workers in the Dominican Republic had used loudspeakers to urge people to evacuate ahead of the worst of the storm, while police arrested a handful of surfers in the capital of Santo Domingo accused of violating government storm warnings.

Especially hard hit was Puerto Rico's southern region, which still shakes daily from aftershocks. Heavy rains inundated neighborhoods weakened by the tremors, causing some recently abandoned homes to collapse.

“Everyone is in a constant state of emergency,” said Marieli Grant with Mercy Corps.

By late Thursday, Isaias had maximum sustained winds of 80 mph (130 kph), making it a Category 1 hurricane. It was centered about 70 miles (110 kilometers) east-southeast of Great Inagua Island in the southeastern Bahamas late Thursday, the U.S. National Hurricane Center said. It was moving northwest at 18 mph (30 kph), and its center was forecast to move near the southeastern Bahamas during the night, be near the central Bahamas late Friday and move near or over the northwest Bahamas and near South Florida on Saturday.

A hurricane warning was issued for the northwestern Bahamas, including Andros Island, New Providence, Eleuthera, Abacos Islands, Berry Islands, Grand Bahamas Island, and Bimini.

Tropical storm warnings were posted for the Turks and Caicos Islands and portions of the Dominican Republic, Haiti and the Bahamas. A tropical storm watch was in effect for the east coast of Florida from Ocean Reef to Sebastian Inlet.

The storm knocked out power to more than 400,000 clients across Puerto Rico, including hospitals that switched to generators, and left some 150,000 customers without water. Crews opened the gates of one dam that last month had such a low water level that officials cut service every other day for some 140,000 customers. Outages also were reported in the neighboring U.S. Virgin Islands.

Other damage including 14% of cell towers down was reported elsewhere across Puerto Rico, where tens of thousands of people still use tarps as roofs over homes damaged by Hurricane Maria in September 2017.

“I didn't think it was going to be this strong,” said José Pagán, a 22-year-old who lives in the eastern mountain town of Juncos and whose home was slightly flooded. “It's a rather difficult experience because it reminds us of Maria.”

More than 50 people sought shelter in Puerto Rico, said Gov. Wanda Vázquez, who urged those living near swollen rivers to find refuge. But many remained wary of shelter given a spike in COVID-19 cases on the island.

In the western town of Mayaguez, Alan Rivera, a 40-year-old engineer, told the AP that the street in front of his house turned into a flowing river — something that didn't even happen during Hurricane Maria. He and his family planned to temporarily move in with his parents despite concerns about the coronavirus.

“We have to take the risk,” he said. “There's no other alternative.”

U.S. President Donald Trump approved an emergency declaration in Puerto Rico as a result of the storm.

Isaias was expected to produce 4 to 8 inches (10 to 20 centimeters) of rain across Puerto Rico, Dominican Republic and northern Haiti, with isolated maximum totals of 10 inches (25 centimeters).

Isaias is the earliest ninth Atlantic named storm to form, according to Colorado State University hurricane researcher Phil Klotzbach. The previous record was Irene on August 7, 2005, Klotzbach tweeted.

So far this year, Cristobal, Danielle, Edouard, Fay, Gert and Hanna have also been the earliest named Atlantic storms for their alphabetic order.
