Hurricane Isaias is expected to make landfall on the Gulf Coast as a Category 2 storm, with insured losses projected to remain in the low single-digit billions, according to multiple risk modeling firms. The storm has intensified faster than initial forecasts, but wind shear is likely to weaken it before impact, reducing potential damage.
Four separate risk modeling firms have provided initial estimates for insured losses from Isaias. Moody’s RMS Event Response placed the range between $2.5 billion and $4.5 billion. Karen Clark & Company (KCC) estimated wind and storm surge losses at $3 billion, while Verisk forecast onshore property losses between $1 billion and $2 billion. Euler ILS Partners also projected losses between $2 billion and $4 billion, noting the potential for additional aggregate losses.
Isaias is the first hurricane of the 2026 Atlantic season, having strengthened overnight into a Category 2 storm. The National Hurricane Center (NHC) previously forecast its development from a tropical depression into a tropical storm, with further intensification expected before landfall. The storm’s path and weakening before impact may limit the total insured losses, though exact figures remain uncertain.

The Caribbean Catastrophe Risk Insurance Facility (CCRIF SPC) has increased its parametric risk pool coverage by 14.5%, raising it to $1.8 billion for the current policy year. This follows earlier expectations of $1.57 billion, reflecting higher demand for parametric insurance solutions in the region. The expansion shows growing reliance on such coverage as hurricane risks evolve.
Forecasts for the broader 2026 Atlantic hurricane season have shifted downward in recent updates. Tropical Storm Risk (TSR) adjusted its projections, citing less favorable sub-tropical Atlantic conditions than initially expected. Meanwhile, Colorado State University (CSU) maintained its prediction of well-below-normal activity, with landfall probabilities continuing to decline as the season progresses. These adjustments suggest a quieter-than-expected season, though local impacts from storms like Isaias can still be significant.
Reinsurance broker Gallagher Re noted that a Category 2 landfall typically results in insured losses in the low to mid-single-digit billions. The storm’s rapid intensification and potential weakening before landfall may further limit financial impacts, though exact figures will depend on its final track and intensity. The NHC continues to monitor the system closely as it approaches the Gulf Coast.
