CLIMATEWIRE | Forecasters warned for days that Tampa could possibly be staring down “the large one” — a direct hit from a significant hurricane that threatened to submerge a lot of Florida’s second-largest metro space with never-before-seen storm surge.
The nightmare state of affairs didn’t occur. Hurricane Milton tracked barely south of its worst-case trajectory, making landfall Wednesday evening in Sarasota County. Storm surge, general, was decrease than the water ranges pushed by Hurricane Helene two weeks prior.
But it was nonetheless a record-breaking storm, dumping historic rainfall alongside the coast and spawning tornadoes that carved a path of destruction throughout a number of counties.

Scientists say local weather change, together with unusually heat waters within the Gulf of Mexico, possible worsened its explosive intensification right into a Class 5 cyclone earlier than it weakened and made landfall as a Class 3.
“What we will say is the storm was vital, however fortunately this was not the worst-case state of affairs,” Florida Gov. Ron DeSantis mentioned at a press briefing Thursday morning.
Tampa was spared largely because of a southward wobble in Milton’s observe within the last hours earlier than landfall, sending the storm towards Sarasota.
That doesn’t imply projections by the Nationwide Climate Service have been inaccurate, mentioned Austen Flannery, a meteorologist with the Nationwide Climate Service’s Tampa workplace. Landfall nonetheless occurred nicely inside the forecast’s cone of uncertainty.
“General, the top consequence was comparatively in step with the forecast,” he mentioned.
Preliminary estimates counsel storm surge was highest in Sarasota County, he mentioned, possible round 8 to 10 ft. That’s considerably lower than the 15 ft the Nationwide Climate Service had warned was doable for Tampa.
But widespread flooding nonetheless occurred throughout the state — partly from surge, however largely due to heavy rains.
Elements of Tampa have been pelted with greater than 10 inches of rainfall. Tampa Worldwide Airport recorded 11.73 inches, in accordance with the Nationwide Climate Service. And the close by metropolis of St. Petersburg noticed practically 19 inches of rain, a month-to-month report.
“In two days, we had extra rain than we’ve ever had within the month of October at that location,” Flannery mentioned.
Sturdy winds additionally blasted the Tampa Bay area, downing timber and energy strains, damaging houses and companies, and ripping the roof off Tropicana Area, the stadium that’s house to the Tampa Bay Rays in St. Petersburg. Preliminary datasets from the Nationwide Climate Service report gusts of over 100 mph in components of Tampa and Sarasota County.
Milton additionally sparked twister outbreaks throughout the state, together with at the very least 45 particular person twister reviews and 19 confirmed touchdowns. The outbreaks triggered greater than 100 twister warnings throughout the state in a single day, a report for Florida, in accordance with native meteorologists.
Scientists are nonetheless digging into the explanations Milton spawned so many twisters. Facets of the storm’s observe and movement throughout the Gulf and its interplay with different climate methods because it moved over Florida possible fostered favorable situations for twister formation.
“It’s going to take a while and scientific evaluation to actually perceive the precise motive for why that was the case,” Flannery mentioned.
One other climate-fueled catastrophe
Local weather change possible helped gas Hurricane Milton’s record-breaking trajectory, scientists say.
The storm underwent a particularly fast intensification because it churned throughout the Gulf, gaining greater than 90 mph in wind speeds over the course of simply 24 hours. It shattered the scientific definition of fast intensification, which the Nationwide Climate Service describes as a rise of 35 mph in a single day.
Document-breaking water temperatures within the Gulf have been a key driver of Milton’s explosive energy. An evaluation by the analysis and communication nonprofit Local weather Central discovered that the water temperatures in Milton’s path have been between 400 and 800 instances extra possible to happen due to world warming.
Usually, researchers have discovered that hurricanes are rising stronger and intensifying quicker because the local weather warms. Meaning a higher proportion of tropical cyclones are prone to spin up into monster storms like Milton within the coming a long time.
Hurricanes are additionally rising wetter as temperatures rise. A hotter ambiance permits them to drag in additional moisture and dump extra rainfall, which means Milton’s historic precipitation can also be a glimpse of the longer term.
Milton’s outstanding twister outbreaks are extra difficult.
The hyperlinks between tornadoes and local weather change are nonetheless poorly understood in contrast with many different excessive climate occasions. Research point out that the general frequency of tornadoes in all probability hasn’t modified a lot due to local weather change — however their geographic patterns could also be shifting over time and inflicting extra outbreaks in components of the Midwest and the Southeast.
Scientists from the analysis consortium World Climate Attribution, which specializes within the hyperlinks between local weather change and excessive climate occasions, are anticipated to launch a fast evaluation of Milton’s ties to world warming as early as Friday.
In the meantime, analysis has already confirmed that Hurricane Helene — which struck Florida’s Gulf Coast simply two weeks earlier than Milton — had clear ties to local weather change.
A World Climate Attribution evaluation discovered that Helene’s excessive rainfall was about 10 % heavier due to the affect of local weather change. And in southern Appalachia, which suffered historic floods, world warming has made these sorts of rainfall occasions as a lot as 70 instances extra prone to happen.
