Newark, CA – October 15, 2020RMS, the world’s leading catastrophe risk solutions company, estimates total onshore U.S. insured losses from Hurricane Delta to be between US$2.0bn and US$3.5bn. The estimate includes losses to the National Flood Insurance Program (NFIP) of between US$200m and US$400m.

U.S. insured loss estimates for Hurricane Delta (US$ billions):

Wind & Surge Inland Flood NFIP Total
1.7 - 2.8 0.1 - 0.3 0.2 - 0.4 2.0 - 3.5

This estimate includes wind, storm surge, and inland flood losses across the impacted states, including Louisiana, Texas, and Mississippi, based on analysis of RMS ensemble footprints in Version 18.1 of the RMS North Atlantic Hurricane Models and estimates from the RMS U.S. Inland Flood HD Model. RMS ensemble footprints are reconstructions of Delta’s hazards that capture the uncertainties surrounding observed winds and storm surge.

The RMS estimate includes a 15% reduction in insured onshore losses due to the cumulative impacts of Hurricane Laura, which damaged much of the same region six weeks earlier.

“The overlapping nature of Delta and Laura will create a complicated claims management and loss attribution process for the industry. Using an innovative combination of high-resolution aerial imagery and machine-learning techniques, the modeling teams at RMS assessed the competing impacts of Hurricane Laura on Hurricane Delta losses. We determined that more than half of the impacted postal codes were also impacted by Laura, representing more than 90% of loss in this event. While Delta caused higher than expected damage to many structures due to pre-existing damage from Laura, reduced overall exposure-at-risk in the overlapping region after Laura means losses attributed to Delta will end up being lower than if Laura had never happened,said Jeff Waters, senior product manager, RMS North Atlantic Hurricane Models. 

Losses reflect property damage and business interruption to residential, commercial, industrial, and automobile lines of business, along with post-event loss amplification (PLA) and non-modeled sources of loss. RMS expects most insured losses will be from residential lines.

The estimate also includes losses to the National Flood Insurance Program (NFIP) in the range of US$200 million to US$400 million. NFIP losses were derived using the RMS view of NFIP exposure based on 2019 policy-in-force data published by FEMA, the Version 18.1 North Atlantic Hurricane Models, and the U.S. Inland Flood HD Model.

In Mexico, RMS estimates insured losses from Delta to be less than US$500 million. The estimate reflects wind losses based on analysis of RMS post-landfall stochastic event tracks in Version 18.1 of the RMS North Atlantic Hurricane Models. The estimate for Mexico includes property damage and business interruption to residential, commercial, and industrial lines of business.

Additionally, RMS estimates insured losses to offshore platforms, rigs, and pipelines in the Gulf of Mexico to not exceed US$1.0bn from wind and wave-driven damages. Offshore losses are based on the October 2020 vintage of the RMS Offshore Platform Industry Exposure Database.

“Unlike Laura, which impacted several deepwater oil and gas platforms earlier in the season, we expect offshore losses from Delta to be driven mainly by shallow water platforms. The storm shut in oil and gas production in the region up to levels not seen since Hurricanes Katrina, Rita, and Ike. However, Delta’s lower intensity and size while in the Gulf limited the wave heights and consequently, offshore losses are expected to be notably lower than those experienced in the 2005 and 2008 events,” said Rajkiran Vojjala, Vice President, Model Development. 

Delta made landfall near Creole, Louisiana on Friday, October 9, 2020 as a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. At landfall, Delta produced sustained winds of 100 mph (160 km/h), according to the National Hurricane Center. Informed by a suite of real-time observational data sources, RMS HWind products estimated comparable winds at landfall. Delta's landfall location and intensity were well-represented by the HWind forecasting products more than 72 hours before the storm crossed into Louisiana.

“As expected, Delta weakened from major hurricane status to a weaker Category 2 storm just before landfall due to a combination of conditions, including high wind shear and cooler sea surface temperatures, both of which restrain a hurricane’s intensity. However, winds strong enough to cause damage expanded in width, increasing the number of coastal properties at risk. Fortunately, Delta rapidly weakened after landfall, which reduced the material wind and water-driven impacts across interior portions of the Gulf states,” said Pete Dailey, Vice President, Model Development.

Hurricane Delta was the twenty-fifth named storm of the 2020 North Atlantic hurricane season, the ninth hurricane, and the fifth U.S. landfalling hurricane of this very active season. Delta was a record-breaking tenth named storm to make landfall in the contiguous U.S. so far in 2020, and a record-tying fourth named storm of 2020 to make landfall in Louisiana. Over six weeks remain in the Atlantic hurricane season, officially ending on November 30.

RMS industry loss estimates for landfalling U.S. hurricanes are comprehensive, reflecting modelled and non-modelled impacts from all major drivers of damage, including wind, storm surge, and inland flooding.

RMS Launches New Climate Change Models

Newark, CA – March 22, 2021 – RMS, the world’s leading catastrophe risk solutions company, today announced the forthcoming launch of a new suite of Climate Change Models to help customers assess the near and long term impacts of climate change on physical assets and their businesses, in order to make the best possible risk and financial decisions.   According to RMS CEO, Karen White, “Today there are no robust or consistent frameworks that can quantify the physical risks posed by catastrophes in a changing climate at the depth required.  The innovative suite of RMS Climate Change Models changes that, giving the market a powerful new set of tools. With increasing Board-level attention, stakeholder scrutiny, and regulatory pressure, businesses need to operationalize climate change analytics to make better decisions and enable better transparency. It is clear that the financial impacts of climate change are not solely a “future problem”. The increasing incidence of wildfires, floods and hurricanes mean that climate change insights need to be incorporated into financial decisions that are being made today, in parallel with long term strategic planning and meeting increasing regulatory, environmental, social and governance (ESG) and TCFD reporting requirements, and investor and customer demands. This necessitates a climate change framework and models fully consistent with today’s catastrophe risk analytics and one which addresses the challenges posed by physical climate change risk and its broad impact across all relevant time scales – from today through to the end of the century.” Most RMS models, including all major peril models, already incorporate the impact of climate change up until now – but more is required to meet the evolving and significant market needs. The new RMS Climate Change Models take our existing capabilities further with forward-looking predictive insights and analysis. The new Climate Change Models empower RMS’s economic modeling framework with the best climate science consensus, including from the Intergovernmental Panel on Climate Change (IPCC).  The new models will be generally available in June for major peril models North Atlantic Hurricane, Europe Inland Flood and Europe Windstorm. Further models and geographies will follow this initial model suite launch. The RMS climate change solutions also include climate change specialist advisory and consulting expertise and regulatory, ESG and TCFD support.   The Climate Change Models address the perils most impacted by climate change and feature: Probabilistic modeling to capture events across different climate change scenarios The ability to adjust time horizons and Representative Concentration Pathways (RCPs) A proprietary industry and economic exposure database to deliver more accurate and impactful climate change models Embeddable software which integrates into existing workflows to facilitate seamless and easy operationalization  Consulting and additional expertise supporting regulatory submissions and activities, and providing insights from these new models today   Commenting on the RMS climate change solutions, Eric Letourneau, SVP, Group Head of CAT Accumulation Management, QBE, said: “The insights on climate risk provided by RMS have enabled us to better understand climate-related risks and opportunities for our business, to report those insights to financial stakeholders, and to develop and test strategy for our business. We can embed these analytics in our business processes, confident that we have consistency with how we measure underwriting risk and capital requirements now and in the future.” The new RMS Climate Change Models, data, and analytics empower organizations to: Understand the impacts climate change may have on capital and assets today and in the future Price and manage risks to better reflect changing conditions Confidently communicate risks posed by climate change to all stakeholders Comply with regulatory submissions in an efficient and sustainable way RMS has been modeling natural catastrophe risk for the insurance industry for more than 30 years and has been leading research into the impact of climate change on catastrophic losses since RMS’s involvement in the 2007 4th IPCC Assessment Report.   You can learn more about RMS Climate Change solutions here:   https://www.rms.com/climate-change

RMS Estimates that Total Insured Losses from the 2020 Western U.S. Wildfires Will Be Between US$7bn – US$13bn

Newark, CA – December 15, 2020 – RMS, the world’s leading catastrophe risk solutions company, estimates insured losses from the record-breaking western U.S. wildfires this season will be between US$7.0 and US$13.0 billion. These losses reflect estimates as of December 1, 2020 and represent an update from the previously estimated losses from fires up to September 20, 2020. The ignition of the highly damaging Glass Fire and additional spread of the CZU and LNU Complex Fires represent the most notable activity in California since September 20. RMS insured losses represent estimates from major wildfires in California, Oregon, Washington, and Colorado at December 1, 2020: Region Insured Losses (USD $ bn) as of 1 December, 2020 Northern California Oregon and Washington Colorado 5.0 - 9.0 1.0 - 3.0 Up to 1.0 The RMS estimate includes losses from property damage, including evacuation and smoke damage, business interruption (BI), and additional living expenses (ALE) across residential, commercial, and industrial lines. Smoke and evacuation are expected to be significant contributors to losses for the wildfires this season, contributing about 20 percent of losses in California and Colorado and about 35 percent in Oregon and Washington. The estimate also accounts for notable post-event loss amplification (PLA) from property damage (25 to 30 percent) and business interruption/ALE (up to 100 percent or greater). The RMS loss estimate is based on detailed modeling of fire spread, ember accumulations, and smoke dispersion of the fires utilizing the U.S. Wildfire High-Definition (HD) Model, part of the North America Wildfire HD Model suite, released in February, 2019. The model covers the entire contiguous U.S. and explicitly simulates ember and smoke to support detailed analysis of the impact of a wildfire beyond historical fire perimeters. The model’s findings were supported by Damage Inspection Specialist (DINS) damage surveys for California Fires, published damage reports from federal and respective state agencies for the Oregon, Washington, and Colorado fires, and the RMS U.S. Wildfire Industry Exposure Database. Michael Young, Vice President, Product Management said: “2020 represents the most destructive fire season on record, in terms of burn area in California. Since August, 69 major fires that exceeded 1,000 burned acres each, have burned so far. Five of the six largest ever California wildfires have occurred in 2020, with over 4.4 million acres burned in total to date. While fires earlier in the season were dominated by ignitions sparked by the intense lightning storm in August, extreme wind-driven fires dominated the last few months. A similar phenomenon resulted in record-breaking fires in Oregon as well this season, with over 20 major fires driven by extreme winds, burning more than 1.2 million acres so far. In October, Colorado experienced its three largest destructive fires with more than 24 major fires burning 850,000 acres in total. Rajkiran Vojjala, Vice President, Model Development said: “This wildfire season reaffirms the growing catastrophic nature of this peril. Wildfire risk is clearly evolving, not only in California, but also in other states, as we observed in Oregon and Colorado. While changing climate patterns have significantly influenced the record-breaking fires this season, several other factors also profoundly affected the ignition potential and expected losses from these events in different ways. Most notable amongst them are the Public Safety Power Shutoff (PSPS) measures undertaken by utilities, preparedness and response of firefighters in Northern California despite COVID-19 challenges, and recent legislative actions governing wildfire claims settlement such as the California Senate Bill 872. RMS is currently engaged with various stakeholders in evaluating these factors and understanding their impact on the emerging risk profile of this peril as part of its wildfire modeling agenda.”   END The technology and data used in providing this information is based on the scientific data, mathematical and empirical models, and encoded experience of scientists and specialists.
