It’s a nightmare state of affairs that has lengthy haunted Florida officers.
For years, scientists and concrete planners have warned that rising sea ranges and worsening tropical cyclones have made storms an even bigger risk to the coastal Tampa Bay space, which incorporates the cities of Tampa, Clearwater and St. Petersburg.

“We’re all conscious of the danger of the ‘massive one’ — a catastrophic main hurricane making landfall,” mentioned Brian Auld, chair of the regional enterprise coalition Tampa Bay Partnership, in a foreword to a 2022 report making an financial case for larger local weather adaptation and resilience efforts within the Tampa area.
Now, two years later, it appears these warnings have come too late. Whereas the area has made some enhancements to handle the specter of a serious hurricane, the tasks nonetheless fall wanting what specialists say is required.
Hurricane Milton is projected to develop into the primary main hurricane to make direct landfall in Tampa Bay in additional than a century. It’s the strongest storm on file to kind within the Gulf of Mexico so late within the season, based on College of Colorado hurricane skilled Philip Klotzbach, reaching Class 5 energy with wind speeds exceeding 175 mph.
And it’s one of many quickest intensifying storms on file. Milton gained greater than 90 mph in wind speeds over the course of simply 24 hours, based on Ken Graham, director of the Nationwide Climate Service.
“That’s the third highest that we’ve got on file behind Wilma and Felix,” he mentioned at a press briefing Monday. “This is without doubt one of the strongest storms we’ve had within the Atlantic basin since Dorian [in 2019]. This isn’t a superb state of affairs — this can be a critical, critical state of affairs.”
The storm weakened in a single day to a Class 4 hurricane. It’s forecast to make landfall Wednesday night as a Class 3 storm.
It’s not simply Milton’s energy that makes the state of affairs so harmful. Tampa Bay’s distinctive geography and the background affect of quickly rising sea ranges makes the area weak to excessive impacts from a lot lesser storms.
Sea ranges alongside components of the Gulf Coast are rising as a lot as thrice quicker than the worldwide common, research have discovered. And a 2019 report from the Tampa Bay Local weather Science Advisory Panel, a consortium of native scientists, warned that the area could also be dealing with wherever from one to 2.5 toes of sea-level rise by the yr 2050. Rising sea ranges put coastal areas at rising danger of storm surge and coastal flooding.
On the identical time, Tampa Bay’s topography — with its shallow shoreline and low-lying communities — make it particularly prone to the impacts of storm surge.
These dangers grew to become obvious simply two weeks in the past, when Hurricane Helene prompted record-breaking storm surge in Tampa Bay, regardless of making landfall greater than 100 miles north in Florida’s Large Bend area. Preliminary tide gauge readings counsel some communities noticed water ranges above 7 toes, in some instances greater than 2 toes larger than their earlier peaks.
Now, scientists say Milton might blow these information away. The Nationwide Hurricane Middle warns that Milton might trigger storm surge of 10 to fifteen toes in Tampa Bay. Specialists already undertaking the storm might trigger tens of billions of {dollars} in damages.
Although stunning, none of this comes as a shock to specialists.
A 2013 report from the World Financial institution positioned Tampa seventh on an inventory of the highest 10 world cities dealing with the most costly harm from coastal floods. And a 2015 report from the Boston disaster danger evaluation agency Karen Clark & Co. positioned Tampa first on an inventory of U.S. cities most weak to storm surge flooding. The examine projected losses of $175 billion within the occasion of a catastrophic hurricane.
Some communities have begun taking measures to guard themselves.
Metropolis Council members within the city of St. Petersburg just lately authorized a $1.6 million development undertaking to rebuild deteriorating seawalls within the Riviera Bay neighborhood, though the undertaking comes too late for Hurricane Milton. Town additionally just lately up to date its Stormwater Grasp Plan, recommending round $1 billion in tasks designed to enhance water high quality and mitigate flooding by the yr 2050.
The close by city of Clearwater is investing $100 million on flood mitigation tasks in its North Seaside neighborhood.
Town of Tampa, in the meantime, has numerous flood mitigation tasks underway in neighborhoods across the metropolis. Town additionally was just lately awarded a $24.7 million federal grant for enhancements to its Palmetto Seaside neighborhood, together with stormwater and flood mitigation tasks.
Emergency mitigation tasks even have proven potential for fulfillment throughout current excessive climate occasions. Tampa Normal Hospital efficiently protected itself from flooding throughout Hurricane Helene by putting in a brief floodwall constructed by Norwegian producer AquaFence.
Nonetheless, metropolis officers have acknowledged that Tampa wants extra long-term funding in local weather resilience. Town launched a 156-page local weather adaptation and fairness plan final yr, outlining suggestions for its transition to a low-carbon, climate-resilient financial system. It famous that Tampa is weak to coastal flooding, storm surge and hurricanes.
Whereas “Tampa averted the worst impacts of Hurricane Ian, the storm is a painful current reminder that our neighborhoods are weak to extreme storms which can be rising in frequency,” the report said.
In the meantime, different native stories from Tampa Bay communities have warned the area should make investments extra assets in local weather adaptation and resilience to defend itself from floods and storms.
The Tampa Bay Partnership’s 2022 report — making an financial case for local weather resilience — referred to as for a wide range of flood-related adaptation measures together with seawalls and different coastal limitations, seaside nourishment and elevated, flood-proof buildings. Whereas these variations are expensive within the brief time period, the report estimated important financial advantages in the long term.
Although the report warned of a worst-case state of affairs hurricane, it additionally famous that flood dangers are already extreme within the case of lesser storms and rainfall occasions.
“Whereas there’s usually speak of the massive storm — the catastrophic main hurricane — the frequent flooding analyzed on this report can have main financial penalties for the area,” the report said. “There’s a compelling case to make for Tampa Bay to put money into resilience proper now.”
