Why Tampa Is So Vulnerable to Hurricane Milton

For much than a century, Tampa Bay has avoided Florida’s astir destructive hurricanes. Now Hurricane Milton whitethorn extremity that streak of luck, arsenic the tempest is expected to marque landfall conscionable southbound of Tampa Bay successful the aboriginal hours of Thursday morning. The low-lying shoreline, inactive strewn with debris from past month’s Hurricane Helene, is bracing for a tempest surge of up to 15 feet.

Tampa Bay’s shallow seabed and built-up coastline marque it peculiarly susceptible to hurricanes. A 2015 report from catastrophe modelers Karen Clarke & Co ranked the Tampa–St. Petersburg country arsenic the astir susceptible metropolis to tempest surge flooding successful the US. Despite aggregate reports echoing the area’s vulnerability to tempest surges, plans to beef up the area’s defenses person been delayed and successful immoderate cases vetoed by Florida politician Ron DeSantis. Now the country volition person to look the astir unsafe tempest successful a period with what successful galore cases are aging tempest defenses.

The geography of Tampa Bay makes it peculiarly ill-equipped to woody with a tempest similar Hurricane Milton. The shallow coastal support and bay’s constrictive rima could harvester with hurricane-force winds to nonstop immense quantities of h2o into a heavy built-up shoreline wherever fractional of the colonisation lives little than 10 feet supra oversea level. As the metropolis boomed during the 20th century, new developments piled up on the shoreline, placing residents adjacent to imaginable tempest surges.

Karen Clarke & Co estimated that the harm of a once-in-100-years hurricane to Tampa Bay could adhd up to $175 billion—more than astir immoderate different hurricane successful US history. A 2019 analysis of the area’s proscription web recovered that large parts of Tampa Bay’s roadworthy system, including 1 causeway and 2 bridges crossing the bay, are highly susceptible to utmost weather. The study called for enhancing drainage, raising roads, and protecting coastlines.

Despite these vulnerabilities, immoderate projects to support Tampa Bay against tempest surges person been dilatory to beryllium enacted. Flooding aft Hurricane Idalia successful 2023 revealed that stormwater pipes were unmaintained, blocked by debris, and not equipped to propulsion retired floodwaters effectively, according to reporting successful the Tampa Bay Times. In August the Clearwater City Council voted to increase stormwater inferior fees to wage for upgrades to the draining system.

But different flood defence projects person been vetoed by DeSantis. A task that would regenerate 30-year-old stormwater infrastructure successful the metropolis of Dunedin successful Pinellas County, which sits betwixt the City of Tampa and the Gulf of Mexico, was vetoed for the 2024–25 fiscal year. Other Pinellas County flood defence projects vetoed by DeSantis see plans to instal power backups astatine sewer pumps, acquisition exigency generators for fire stations, reroute stormwater, and defend a theater from floodwater.

Projects vetoed successful Hillsborough Country, implicit the bay from Pinellas, include a plan to marque a wastewater attraction installation much robust to terrible upwind events and a task to instal 3,500 feet of mangroves and oyster reefs that could assistance trim the tallness and spot of tempest surges.
