Hurricane Elsa track moves slightly away from South Florida

The projected path of Hurricane Elsa shifted slightly away from South Florida on Saturday morning as the system continued to barrel through the Caribbean, but forecasters caution there’s still considerable uncertainty about the storm’s likely course.

The storm’s forecast cone shifted west, removing almost all of coastal South Florida. But some models still show it striking the region, and the National Hurricane Center said there’s unusual uncertainty in the long-term track. And the cone shows only the possible locations of the storm’s center, which means hurricane-force or tropical-force winds could extend well outside the cone.

Elsa’s forward speed of 31 mph makes it the fastest-moving Atlantic hurricane on record, according to The Weather Channel.

Elsa, which is moving west-northwest, weakened overnight and was producing sustained winds of 75 mph, according to the 8 a.m. advisory from the National Hurricane Center. That wind speed put it just over hurricane strength, which requires a wind speed of at least 74 mph.

The hurricane was located 110 miles southeast of Isla Beata, Dominican Republic, according to the National Hurricane Center, and 440 miles east-southeast of Kingston, Jamaica. Hurricane-force winds extend 25 miles from Elsa’s center and tropical storm-force-winds extend 125 miles from the center.

Elsa is expected to slow down a bit later today and tonight and turn northwest Sunday night or Monday.

Land, especially mountains in Cuba, remain the biggest factor in reducing Elsa’s intensity before its possible Florida arrival.

Elsa’s rapid pace means it will have difficult maintaining hurricane strength, according to experts. Hurricanes are most effective when they’re straight up and down, such as a chimney, according to National Weather Service meteorologist Joel Cline.

“If one section is moving faster than the other, e.g. in this case the lower level is moving forward at 25 to 30 mph and the mid-level of the same tropical system is moving about 15 mph, then the difference in those winds would shear the chimney and the smoke comes out the bottom of the chimney and the fire goes out,” Cline said in an email.

“In the tropical system, the system would fall apart with the low-level center and likely no convection or storms moving away from the mid-level center, and thus nearly all the convection would die out and the system dies.”

The current forecast path takes Elsa over the southern coast of the Dominican Republic and Haiti tonight, and near Jamaica and portions of eastern Cuba on Sunday.

By Monday, the hurricane center said, Elsa should be moving across central and western Cuba and toward the Florida Straits.

The earliest reasonable arrival of Tropical Storm-force-winds in South Florida is Sunday night, according to the hurricane center.

The most likely arrival of Tropical Storm-force-winds in South Florida is Monday morning or afternoon.

By Sunday, Elsa is forecast to be near Jamaica and portions of eastern Cuba.

However, the hurricane center has been quick to add the forecast is uncertain beyond three days.

The storm became the season’s first hurricane Friday morning, and nearly the entire state of Florida is in its forecast cone of uncertainty.

Any local impacts from Elsa would come after the July 4th holiday, according to Robert Garcia, a meteorologist with the National Hurricane Center. That means the scheduled fireworks shows in Broward and Palm Beach counties should be unaffected by Elsa unless the forecast changes.

Even though much is still uncertain, Broward Mayor Steve Geller on Friday urged residents to stock up on hurricane supplies now while they are readily available rather than waiting later in the hurricane season.

“Have enough water and non-perishable food at home as well as batteries ... If you can, get prepared now for the hurricane season,” Geller said.

He also encouraged residents to make sure they have all they need to board up and put on hurricane shutters ahead of a major storm.

“We’ve all been there before and we know people have a tendency to wait,” he said. “...Please prepare now for the entire hurricane season.”

Local officials from the airport, water control and electric companies are also keeping a close eye on Elsa.

Fort Lauderdale-Hollywood International Airport is monitoring the situation, according to spokesperson Arlene Satchell.

“Right now, we’re not under any hurricane watches or warnings,” she said. “We’ll continue to monitor the path of the storm and we’ll make adjustments it if becomes a threat to the region.”

Satchell suggested travelers check with their airlines for possible delays or cancellations.

Randy Smith, spokesman for the South Florida Water Management District, said they’re lowering canals in Broward and Miami-Dade counties and sending the water to the ocean through gates and pump stations.

“We’ll put them in a low range and that’s because we anticipate significant rainfall from Elsa,” he said.

Smith also said people should check neighborhood drainage areas and make sure nothing is blocking the path. Otherwise, the water could back up and flood.

“Don’t wait until it starts raining,” he said.

Smith said if a big clearance job is required people should call their local public works department.

Florida Power & Light is also monitoring Elsa. It said customers can go to FPL.com/storm for information on things such as outages.

“We’re ready,” spokesman Peter Robbins said. “We have trained for storms year-round. We’ve got our people and equipment on standby and we’ll keep watching and see how it develops.”

Robbins said at this point it’s too late to trim trees because trash pickup could be disrupted by Elsa’s approach.

Hurricane Elsa could also disrupt travel plans on the busy July 4 weekend. Florida expects to have 2.6 million drivers on the roads, according to AAA The Auto Club Group. Last year, in the midst of the COVID-19 threat, Florida has just fewer than 2 million drivers on the road for July, according to AAA.

Elsa was being watched carefully by officials in Surfside, as well.

”Any bad significant wind could potentially bring down the remaining part of that building,” T.J. Lyon, chair of Florida’s Statewide Emergency Response Plan, told weather.com. ”Any bad weather is going to have a significant impact on the incident scene.”

Elsa’s track and intensity are still being watched carefully.

“This forecast is most complicated by land interaction,” meteorologist Jonathan Belles of The Weather Channel said in an email. “We don’t know exactly how this system will interact with Hispaniola, Jamaica or Cuba this weekend. The more interaction Elsa has with those countries, the weaker the storm will be as it gets closer to Florida.

“A secondary factor that we’ll be watching with this system is its forward speed. It is being shoved westward at a much faster clip than most systems can sustain themselves at, but this forward speed should slow down somewhat. Wind shear is a concern with this storm too, but to a lesser degree than the other two factors.”

Elsa is a record-breaker, becoming the earliest-forming fifth storm in recorded history. The previous record was held by Tropical Storm Eduardo, which formed on July 5, 2020.

Elsa’s hurricane development is 39 days ahead of when meteorologists typically observe the first hurricane formation of the season; which on average usually happens on Aug. 10, according to the National Oceanic and Atmospheric Administration’s database.

Forecasters mentioned Elsa’s possible development into a hurricane Thursday, but there was no hint it would develop so quickly.

“I would say at this point, with a Tropical Storm being forecast, it isn’t unreasonable for South Floridians to be ready for the potential of a Category 1 hurricane knocking on our door early next week,” Garcia said.

“It is something that can’t be ruled out, and folks should be aware that’s something we may have to prepare for here during the holiday weekend.”

Whichever way the system goes, Elsa seems sure to bring rain to already-saturated South Florida — and it could bring lots.

A hurricane warning is in effect for the south coast of the Dominican Republic from Punta Palenque to the border with Haiti, and the southern portion of Haiti from Port Au Prince to the southern border with the Dominican Republic.

A Tropical Storm warning is in effect for St. Vincent and Grenadines, St. Lucia, Martinique, Dominica, the coast of Haiti north of Port Au Prince, the south coast of the Dominican Republic east of Punta Palenque to Cabo Engano, and Jamaica.

A hurricane watch in effect for Jamaica.

A Tropical Storm watch is in effect for Grenada, Saba and Sint Eustatius, the north coast of the Dominican Republic from Cabo Engano to Bahia de Manzanillo, and Cayman Brac and Little Cayman.

The determining factor of where Elsa goes, and when it turns north from its current westward direction, is the Bermuda High, a high-pressure system that is the storm’s steering mechanism. It’s essentially what deflects storms from Florida or allows them near.

“This influence will last into the weekend before we start to reach the western edge of the Bermuda High and begin to turn northward,” Belles said.

“If the Bermuda High is strong, storms often go westward into Central America,” he said, “but if that Bermuda High is weaker, storms can recurve northward over the Greater Antilles and out into the Atlantic. It appears that Elsa will split this envelope of climatology down the middle.

Last year’s first hurricane, Hanna, developed into a hurricane and made landfall in Texas on July 25.
