Hurricane Irma

In this study, it is demonstrated that hurricane wind intensity, forward speed, pressure, and track play an important role on the generation and propagation of coastal storm surges. Hurricane Irma, which heavily impacted the entire Florida peninsula in 2017, is used to study the storm surge sensitivity to varying storm characteristics. Results show that the west coast experiences a negative surge due to offshore wind of the approaching storm, but the positive surge returns after the hurricane eye passes over a location and wind became onshore. In the west coast peak, surges are intensified by an increase in onshore wind intensity and forward speed. In the Florida Keys, peak surges are intensified by an increase in wind intensity, a decrease in forward speed and a decrease in pressure. In southeast and east Florida, peak surges are intensified by decrease in pressure, although overall surges are less significant as the water can slide along the coastline. In the recessed coastline of Georgia-Carolinas, maximum surge is elevated by an increase in onshore wind intensity. Shifting the track westward increases peak surges on the west coast, while shifting the track eastward increases peak surge on the east coast. The results demonstrate a new understanding about the sensitivity of surge to varying parametric conditions and the importance of considering changes in the coastline orientation in storm surge predictions.

Offshore Wind Industry

The state of California stands at a crossroads where many different enablers are now coming together to spur its leadership in a new offshore wind energy industry off the west coast of the US. This paper presents the rationale for this new industry to be built from the ground up and elaborates on the development efforts recently undertaken by Principle Power Inc. (PPI) to jumpstart this important opportunity. The paper will first focus on the unique value proposition offshore wind offers to the Golden State and discuss the path the company has taken to accelerate the development of the offshore wind industry along the coast, with the proposition of a flagship project in Humboldt County.

Sea Level Variability

AbstractA storm surge hindcast for the west coast of Canada was generated for the period 1980–2016 using a 2D nonlinear barotropic Princeton Ocean Model forced by hourly Climate Forecast System Reanalysis wind and sea level pressure. Validation of the modeled storm surges using tide gauge records has indicated that there are extensive areas of the British Columbia coast where the model does not capture the processes that determine the sea level variability on intraseasonal and interannual time scales. Some of the discrepancies are linked to large-scale fluctuations, such as those arising from major El Niño and La Niña events. By applying an adjustment to the hindcast using an ocean reanalysis product that incorporates large-scale sea level variability and steric effects, the variance of the error of the adjusted surges is significantly reduced (by up to 50%) compared to that of surges from the barotropic model. The importance of baroclinic dynamics and steric effects to accurate storm surge forecasting in this coastal region is demonstrated, as is the need to incorporate decadal-scale, basin-specific oceanic variability into the estimation of extreme coastal sea levels. The results improve long-term extreme water level estimates and allowances for the west coast of Canada in the absence of long-term tide gauge records data.

Abstract. On 10 September 2017, Hurricane Irma made landfall in the Florida Keys and caused significant damage. Informed by hydrodynamic storm surge and wave modeling and post-storm satellite imagery, a rapid damage survey was soon conducted for 1600+ residential buildings in Big Pine Key and Marathon. Damage categorizations and statistical analysis reveal distinct factors governing damage at these two locations. The distance from the coast is significant for the damage in Big Pine Key, as severely damaged buildings were located near narrow waterways connected to the ocean. Building type and size are critical in Marathon, highlighted by the near-complete destruction of trailer communities there. These observations raise issues of affordability and equity that need consideration in damage recovery and rebuilding for resilience.

Hurricane Irma

Hurricane Irma was a major Hurricane in the 2017 tropical season that reached category 5 and caused catastrophic damage in parts of the northeastern Caribbean and the Florida Keys. Irma was the strongest observed storm and the most intense in the Atlantic since 2005. Irma developed on August 30, 2017 near the west African coast then intensified into a hurricane on the Saffir– Simpson scale within one day. Irma became a major storm at Category 3 hurricane On September 5, 2017 then reached its peak of Category 5 hurricane with intensity of 185 mph (295 km/h) winds. Irma was a Category 4 hurricane, before making landfall on The Florida Keys and was a major Category 3 by the time it made a second Florida landfall on Marco Island and Naples in Southwest Florida on Sunday September 10, 2017. Irma weakened to a category 2 hurricane later that day as it tracked along the Florida peninsula. This paper discusses morphologic responses to the storm in Southwest Florida where Irma made landfall at Marco Island and Naples. FDEP (2018) provides documentation of the post-storm beach conditions and coastal impact of Hurricane Irma throughout the state of Florida, This paper focuses on case studies in Southwest Florida.
