Guidewire Software Inc. Unveils Spring Weather Assessments Amid Escalating Climate Risks

Springtime in the United States is notorious for its unpredictable weather patterns, particularly in the central and southeastern regions. The combination of warm, moist air meeting cold, dry systems can give rise to violent tornadoes, damaging hailstorms, and severe flooding. Guidewire’s HazardHub provides a detailed analysis of these seasonal threats, highlighting their growing impact on property damage and insured losses nationwide.

According to the HazardHub Tornado Risk Score, nearly 4.8 million housing units—representing 3.4% of all homes in the U.S.—are situated in high or very high-risk tornado zones. The year 2024 was recorded as the second-most active year for tornadoes in the United States, with a staggering 1,796 tornadoes reported, trailing only behind 2004.

Severe Convective Storms (SCS) have emerged as significant contributors to insured losses, leading to a record $65 billion in damages in 2023, primarily driven by hail. The HazardHub Enhanced Hail Risk Score indicates that an overwhelming 99.72% of U.S. housing units are at risk of hail, with less than 1% classified in high-risk areas. Hail alone accounts for about 20% of all property and casualty insurer payouts.

Flooding remains the most costly natural disaster in the U.S., with 90% of all natural disasters involving flooding, as reported by FEMA. Alarmingly, only 4% of U.S. homeowners have flood insurance, despite increasing risks from extreme rainfall and outdated FEMA mapping. HazardHub identifies Texas, Louisiana, and California as states with the highest potential for riverine flood losses, while New Jersey, New York, and Virginia are particularly vulnerable to coastal flooding.

Tammy Nichols Schwartz, Senior Director of Data and Analytics at Guidewire, emphasized the significance of HazardHub's property-specific risk scores, stating, “With HazardHub's property-specific risk scores, insurers can better assess exposure, and policyholders can take proactive steps to protect their homes.” She highlighted that insurers can leverage these scores to navigate the changing risk landscape effectively.

The increasing destructiveness of spring weather events is underscored by Gallagher Re’s findings, which indicate a 9.6% annual increase in insured losses from Severe Convective Storms since 2000. Factors contributing to this trend include suburban expansion and heightened property exposure in high-risk areas. Common losses during the spring season include structural damage, power outages, and water intrusion, leading to significant financial burdens on homeowners and insurers alike.

As the spring season approaches, the risk landscape for homeowners and insurers appears increasingly perilous. Guidewire's HazardHub provides crucial data that can aid in risk assessment and management, empowering both insurers and policyholders to mitigate potential damages. With the volatile nature of spring weather events, it is more important than ever for stakeholders to stay informed and prepared.
