A falling tree and generator fumes killed Isaias's two Florida victims
Hurricane Isaias killed four people and cut power to at least 600,000 after reaching Florida with 105 mph winds. Its downgrade to a post-tropical cyclone leaves the flood threat in place, with NOAA warning of up to 10 inches of rain in Georgia and the Carolinas.

What happened
- Alabama, Florida and Georgia declared states of emergency before the storm arrived, and Florida and Alabama ordered thousands of people to evacuate.
- Both Florida deaths were in Escambia County, where Sheriff Chip Simmons said a woman died after a tree fell on her house.
- The second Escambia death was a man poisoned by carbon monoxide from a generator run in a poorly ventilated garage, and four others from the house went to hospital.
- A sheriff in Alabama was injured when a tree fell on him as he responded to a car crash.
- Florida National Guard soldiers swam to a truck stuck in a flood ditch and pulled its occupants out, one of several rescues from submerged vehicles.
Why it matters
- What it limits constraint Any comparison of Isaias's harm with its wind strength stays provisional until Alabama describes how its two victims died, because those cases are half the toll.
- Who's exposed exposure Households running generators in garages or other closed spaces remain at risk of carbon monoxide poisoning after the wind drops, for as long as they depend on them.
- Who's exposed exposure Night driving is the risk Charleston singled out, asking people to stay home ahead of a 7.5ft tide because floodwater depth cannot be judged from behind the wheel.
- Who has to decide decision Alabama residents with weekend travel plans now have to weigh trips against the spinoff tornadoes Governor Kay Ivey said officials were worried about.

Four deaths is a small denominator. Officials have described how only two of those people died, and both were the Escambia County cases [19].
Joey Williams gave NewsNation a first-hand account of a death caused by a falling tree. He said he and his wife had gone outside to photograph the sky and the storm damage, and that after they went back in, a tree fell through the roof and trapped them [11]. "I was able to squeeze out. My wife didn't make it," he said [12].
The other half of the toll is in Alabama. "Unfortunately, we have also learned that two Alabamians have lost their lives," Governor Kay Ivey said in a post on X, without giving details of the circumstances [15]. The BBC's summary says the deaths included people killed when trees fell on their houses [4]. The only such case it describes is in Florida [9].
On the reported record, falling trees account for at least one of the four deaths, or 25 percent, and carbon monoxide from a generator for one more [20]. That is too few cases to say trees did most of the killing. We'd expect the final tally to lean toward falling trees and the hazards that follow a storm, over injuries from the wind itself. Those are the only causes any official has described so far. The expectation holds only if Alabama's two cases fit the same pattern [19].
The outage figure is a Saturday-afternoon snapshot from poweroutage.us, spread across several states [2]. The report does not say how many customers those utilities serve, so the share of the grid that failed cannot be worked out from it. The generator death is the one place where the outage and the death toll may connect. That link is our inference from how people use generators when the power goes; the sheriff's reported account covers only the generator and the unventilated garage [10].
After the downgrade, Florida's warnings turned to water. Governor Ron DeSantis said flooding remained a risk and warned of a "very hazardous situation" [13]. The storm is expected to keep weakening as it travels north-east [5].
Isaias was the first hurricane of an Atlantic season that the BBC says was largely delayed by El Nino conditions in the Pacific [6].
What to watch
- Alabama officials releasing the circumstances of the state's two deaths, which would settle whether falling trees account for most of the toll.
- Outage counts over the following days, and whether more carbon monoxide cases tied to generator use are reported.
- Rainfall totals in Georgia and the Carolinas measured against NOAA's warning, and what Charleston's Saturday night high tide does to its streets.
