Royal Bahamas Police Force remove a body

Personnel from the Royal Bahamas Police Force remove a body recovered in a destroyed neighborhood in the wake of Hurricane Dorian in Marsh Harbour, Great Abaco, Bahamas. About 1,300 people remain missing.

The National Hurricane Center stated the disturbance which had become a tropical depression Friday afternoon had strengthened to a tropical storm Friday night, earning the name Humberto.

The storm, positioned about 130 miles east-southeast of Great Abaco Island in the northwestern Bahamas, was packing 40 mph maximum sustained winds and was headed northwest at 6 mph.

In a positive development, the track forecast for Humberto has shifted east of Florida and so the Hurricane Center dropped the tropical storm watch for the Sunshine State.

While tropical-storm-force winds are no longer anticipated, the Hurricane Center stated “heavy rainfall and scattered flash flooding is possible this weekend in coastal sections of eastern Florida, Georgia, and South Carolina.”

Less than two weeks after being devastated by Hurricane Dorian, both Grand Bahama and Abaco Island were under tropical storm warnings on Friday morning.

The system in question, currently classified as a “potential tropical cyclone,” is currently 140 miles southeast of Great Abaco.

The system was forecast to gradually become better organized and inch ever closer to the Northwest Bahamas this past Saturday.

The United States could be next in line, though uncertainty abounds.

The most likely scenario at this point calls for a close shave or a pass just off the Florida coast.

Between its current location and Florida lies the northwest Bahamas, where recovery efforts are underway following the direct hit from Hurricane Dorian, which was one of the strongest Atlantic storms ever to make landfall.

The developing storm is likely to bring heavy rains and gusty winds to the storm weary region, which could be disruptive for ongoing recovery operations.

The National Hurricane Center said on Friday morning that “this system is not expected to produce significant storm surge in the northwestern Bahamas.”

In contrast, Hurricane Dorian is thought to have produced as much as a 23-foot storm surge in that region.

The National Hurricane Center estimated only a 10% chance of tropical storm force winds — sustained at 39 mph or greater — reaching the city.

Farther north, impacts could be a bit greater depending on how close the center of circulation gets to the coast.

A tropical storm watch has been posted from Jupiter Inlet to the Flagler/Volusia County line.

Potential tropical-storm-force winds, heavy rainfall, rip currents and isolated tornadoes are possible along this stretch of coastline if the current forecast track is realized.

A couple inches of rainfall would also be possible.

Elsewhere, if this storm track is accurate, the bulk of the precipitation should remain relegated to the immediate shoreline or just offshore.

Even in the most likely “brush with the coast” scenario, forecasters are not confident about the track of soon-to-be Humberto past Florida.

Will it recurve out to sea?

Possibly.

There is a moderate chance of it scooting out to sea after flirting with the Sunshine State.

Because the storm is so weak right now, with a poorly defined circulation center, computer models are having a hard time getting a firm handle on the storm’s track beyond 48 to 72 hours.

There’s a possible threat of it being forced to ride up against the east coast, similar to Dorian, or even driven inland somewhere.

The longer it stays over water, the better the chance it has to intensify into a hurricane.

The forecast is trending more with the offshore idea, but the Hurricane Center cautions that uncertainty is higher than usual, and likely will remain that way until the storm organizes further.

Some models bring the developing system inland into the Florida peninsula.

This scenario is less probable than the near-shore track currently expected.

In this scenario, the fledgling disturbance could make landfall as a tropical storm sometime over the weekend between the Treasure Coast and Daytona Beach.

If landfall were to occur, it’s unlikely that the system would be above tropical storm intensity at that point, given a limited window for development over open water.

This storm scenario could bring winds gusting over 40 mph, 2 to 4 inches of rainfall with localized 5+ inch amounts, and a low-end tornado risk to parts of Florida.

Who gets what is unclear at this point, since specific hazards are highly dependent on the track and storm intensity at that point.

In any case, this would not be a “board up and get out” sort of event.

It would be more a “don’t drive through flooded roads” and “don’t be swimming in the surf” type of system.

It’s also possible that, after impacting the Northwest Bahamas, the system could pass out to sea.

The European model advertises this solution.

However, this comes just a couple runs after the European model was calling for a New England landfall.

When the models exhibit a wishy-washy “windshield wiper effect,” vacillating between wildly different projections, it’s indicative that we’re dealing with a very low-confidence forecast.

However, a solution that brings the storm entirely out over the Atlantic is certainly possible.

Initial model runs several days ago alluded to the potential passage of this system over Florida and eventually into the Gulf of Mexico.

In their early depictions, the tropical wave would grow some over the northeast gulf, making a run at the Florida panhandle, coastal Alabama, Mississippi or even Louisiana.

This option is no longer on the table, as most computer models no longer depict it as the lineup of weather systems.

Computer models can’t get a good handle on the future location and intensity of what is likely to become tropical storm Humberto until it is better organized.

The level of organization greatly affects how nearby weather systems interact with the storm.

Odds are forecasters won’t have a better grasp on the storm track for another 24 to 36 hours.
