Verisk’s AIR Worldwide Updates Losses for Hurricane Ida to Include Impacts of Inland Flooding

Wind and storm surge losses will range from USD 17 to USD 25 billion, and private-market insured losses from inland flooding will range from USD 2.5 billion to USD 5 billion

BOSTON, Sept. 13, 2021 (GLOBE NEWSWIRE) -- Extreme event modeling firm AIR Worldwide updated its insured loss estimates for Hurricane Ida after analyzing the inland flood impacts across the entirety of its track, including the Northeast. AIR now estimates that Ida’s insured industry losses will range from USD 20 billion to USD 30 billion. AIR estimates wind and storm surge losses will range from USD 17 to USD 25 billion, and private-market insured losses from inland flooding will range from USD 2.5 billion to USD 5 billion.

Included in the estimates are losses to onshore residential, commercial, industrial properties, and automobiles for their building, contents, and time element coverage, as well as estimated insurance take-up rates for wind and flood across the entirety of Ida’s track, including the flooding that occurred in the Northeast. AIR’s losses do not include any estimate of losses from the National Flood Insurance Program, or any losses from offshore assets. The industry loss estimates also reflect an adjustment to account for increased material and other repair costs in the current construction market.

Hurricane Ida made its first landfall as a Category 4 storm near Port Fourchon, Louisiana, about 60 miles south of New Orleans, at 11:55 a.m. CDT that day, with a maximum sustained wind speed of 150 mph. Ida made a second landfall just hours later at 2 p.m. CDT southwest of Galliano, Louisiana, with a maximum sustained wind speed of 145 mph. The storm produced heavy rains and dangerous storm surge.

The remnants of Hurricane Ida doused the Northeast and caused flooding damage and disruption across the region. Flooding was reported from Pennsylvania to Massachusetts, with New York, New Jersey, and Pennsylvania bearing the brunt of the impact.

In addition to the precipitation-induced flood impacts, damage was reported across several states due to hurricane-spun tornadoes. Further, some of the neighborhoods across the inland and northeastern states saw damage resulting from trees falling on homes. There were reports of many trees uprooting due to antecedent saturated soil conditions due to rainfall from Hurricane Henri a few weeks ago. Claims arising from these would be paid under the wind category.

According to AIR and Xactware analyses, materials costs have gone up significantly in the past year from supply chain disruption in the construction market. Although these costs have moderated since their peak in July when they were 80% higher than September of last year, they remain about 30% higher. (Click this Xactware link for more details.) Repair costs are still up significantly.

Reconstruction costs are more expensive today than they were a year ago. The increase in the total reconstruction cost index means that costs are higher on average nationally; this affects the low- as well as the high-severity events. The difference in magnitude of the impact will come from the mix of construction materials used. For example, minor wind losses are less likely to require repairs that use more expensive inputs such as structural lumber; however, dwellings that are a total loss would require a broader mix of inputs that reflect the higher increases indicated by the total reconstruction index. These increases are outside the scope of demand surge, which tries to answer the cost increase question from a post–extreme event perspective. Therefore, companies should bear these increases in mind and should expect the average claim to be higher before considering demand surge.

An additional source of uncertainty related to materials cost demand surge is the cost of diesel fuel, which has been impacted by the shutdown of refineries during Ida; this fuel would be used to transport materials. While some of these facilities were undamaged, the uncertainty around the timing of the restoration of the power grid and lack of electricity in the meantime is going to keep some of them from coming back online and contributing to the diesel fuel supply.

AIR’s modeled insured loss estimates include:

  • Insured physical damage to property (residential, commercial, industrial, auto), both structures and their contents from winds, wind-borne debris, storm surge, and precipitation induced flooding
  • Additional living expenses (ALE) for residential lines and business interruption losses for commercial lines
  • A 5% leakage is assumed to estimate the amount of damage/losses caused by storm surge attributed to wind for residential lines
  • The losses reflect the insured estimates of precipitation-induced flood supported by the private flood residential market
  • The loss estimates for commercial and industrial lines reflect insured estimates of precipitation-induced flood and storm surge, which is a combination of leakage and take-up depending on the market segment
  • For the automobile line, estimates reflect AIR’s view that insurers will pay for all the precipitation-induced flood and storm surge damage in addition to damage from wind

AIR’s modeled insured loss estimates do not include:

  • Losses paid out by the National Flood Insurance Program
  • Losses arising from hurricane-spun tornadoes, particularly in the inland and northeastern states impacted by Hurricane Ida
  • Losses arising from trees uprooting and falling on homes due to saturated soil conditions in parts of the impacted inland and northeastern states, some of which could end up being paid as wind-related claims
  • Losses to inland marine, ocean-going marine cargo and hull, and pleasure boats
  • Losses to uninsured properties
  • Losses to infrastructure
  • Losses from extra-contractual obligations
  • Losses from hazardous waste cleanup, vandalism, or civil commotion, whether directly or indirectly caused by the event
  • Loss adjustment expenses
  • Losses for U.S. offshore assets and non-U.S. property
