Workers remove a modular house for oil spill relief workers from a marina in Port Fourchon, La., ahead of the arrival of Bonnie, which was downgraded to a tropical depression Friday after lashing Florida. Weather forecasters warned that Bonnie could regain tropical-storm strength as it crosses the Gulf of Mexico.

Some ships prepared to move back to the site of BP's broken oil well Saturday as the remnants of a weakening Tropical Storm Bonnie rolled into the Gulf of Mexico.

The rough weather is still expected to hit the area directly, but the storm — now barely a tropical depression — broke apart as it crossed Florida and moved into the Gulf.

Dozens of vessels evacuated the Gulf Friday ahead of the storm on the orders of retired Coast Guard Adm. Thad Allen, the federal government's spill response chief.

But by Saturday morning, the rig drilling the relief tunnel that will blast mud into the broken well to permanently seal it already was getting ready to head back, BP spokesman Steve Rinehart said.

"It was a quicker turnaround than what it looked like it was going to be when the storm was predicted to be bigger and more intense," Rinehart said.

The vessels relaying video images and seismic readings from undersea robots monitoring the leaky well are still in place and may be able to stay, he said.

The mechanical cap that has mostly contained the oil for eight days was left closed, and there was no worry the storm would cause problems with the plug because it's nearly a mile below the ocean's surface.

The government's spill-response team held off on any blanket order for resuming the drilling and cleanup activities.

"The consensus here is they're still monitoring the storm," spokesman Jonathan Groveman said. "I think decisions are being made on an hourly basis."

The improving forecast means crews are likely to start drilling again sooner than previously expected.

"The ability to move back sooner will obviously allow it to return to relief well activity sooner than it appeared before," Rinehart said.

More weather threats ahead?
Still, the storm has affected the operation. Work on the relief tunnel stopped Wednesday, and it will take time to restart. Crews on the drilling rig pulled up a mile of pipe in 40-to-60-foot sections and laid it on deck of the drilling rig so they could move to safer water.

And the threat of severe weather remains. Hurricane season moves into its most active period in early August and extending into September. The season runs from June 1 through Nov. 30.

Even as the storm weakened, workers on land readied for a possible storm surge that could push oil into the sensitive marsh areas along the coast.

On the tiny resort island of Grand Isle off the southeast Louisiana coast, workers packed up the oil removal operation, tearing down tents, tying down clean boom and loading oil-soaked boom into large containers so it won't pollute the area if the storm causes flooding.

"We're planning for a 2-to-3-foot storm surge so anything that would be affected by that is being moved or stored," said Big Joe Kramer, 55, who is working on his fourth large spill for Miller Environmental Services, Inc.

Before the cap was attached and closed a week ago, the broken well spewed 94 million gallons  to 184 million gallons into the Gulf after the BP-leased Deepwater Horizon rig exploded April 20, killing 11 workers.

The plug is so far beneath the ocean surface, scientists say even a severe storm shouldn't damage it.

"There's almost no chance it'll have any impact on the well head or the cap because it's right around 5,000 feet deep and even the largest waves won't get down that far," said Don Van Nieuwenhuise, director of professional geoscience programs at the University of Houston.

Video: Tropical Storm Bonnie hits Florida

  1. Transcript of: Tropical Storm Bonnie hits Florida

    HOLT: we turn to The Weather Channel 's Jim Cantore , who's in Naples , Florida , with the latest on where this storm is now, where it's headed, and what it might mean for all that oil in the gulf. Jim , good evening.

    JIM CANTORE reporting: Yeah, good evening, Lester . Yeah, you wouldn't know we had a storm here today, that's for sure. The sun is back out here in Naples , and the storm continues to push on to the northwest. Let's take a look at that projected path and time it forward, shall we? And as you can see, we get into Saturday, that's when it'll be over the heart of the oil spill and making its way onshore by Saturday night. So those will be the major impact times. But in the meantime, look at these impacts. Surface winds from the east-southeast will allow these seas to build possibly 10, as high as 12 feet. As we heard from Thad Allen today, that's a good thing. That helps to mix up and even break up the oil. The bad news is, according to the NOAA forecast, that dark blue area that you see there surrounded by the hatched blue area is where the heaviest concentrations of oils are, and that means Breton Sounds and the Chandelier Islands will deal with this. About 150 miles of coastline are expected to be impacted, Lester . That could be less by time all is said and done than what we had with Alex .

    HOLT: Thanks, Jim Cantore .
