Preliminary RMS Analysis of Potential Losses from Hurricane Irma

For the last 48 hours, all the forecasts have been consistent in indicating that Hurricane Irma will have a significant impact in Florida, most likely making landfall in the state. The latest RMS HWind forecast shows it tracking more westerly than before, and this reduces the potential for loss because of the relative concentrations of exposure in the southern end of the Florida peninsula.

Based on today’s long-range forecast, RMS calculates there is still a 10 percent chance of wind losses from Irma exceeding US$85 billion. This assumes a U.S. landfall, with the scenarios in RMS modeling showing almost all of that insurance loss to be in Florida.

But the loss range in this preliminary analysis could easily move higher or lower depending on shifts in the storm track and its intensity. Irma’s anticipated direction of travel has been changing continually through the week, oscillating between both coasts of Florida. It is likely that this changeability will continue, and so the modeling uncertainties remain significant.

RMS will continue to update its analysis of potential insurance losses as Hurricane Irma moves closer to the U.S. coast.
