Abstract

Rising coastal temperatures and intensity of heatwaves increasing the extremity of flooding events pose growing threats to the health and resilience of coastal communities. Building on recent global compound hazard assessments (Zhou et al., 2024), this study provides a high-resolution analysis of heatwave trends across the Tampa Bay area from 1993 to 2026 using land surface temperatures (LST). To evaluate compound hazards, flood maps were sourced for comparison. LST’s were derived from 30 m Landsat imagery to characterize temperature increases in the region. Utilizing LST climatology and land cover maps, spatial and temporal warming trends were investigated. Areas of rapid urban expansion and high urban density show the strongest warming signals, with land cover change emerging as a key driver of localized LST increases.

Additionally, a model was developed to estimate air temperature from LST, but due to data issues was unable to be used for predictions and saved for future work. Instead, heatwave frequencies were analyzed using in situ temperature data from local weather stations. Comparing LST with storm surge and tidal flooding maps reveals hotspots of compound heatwave-flooding hazards across Tampa Bay, identifying areas of concern for the region.
