Hurricane Isabel: Wind and Surge Damage
Hurricane Isabel: Lessons and Outcomes
RMS modeled windfield matched well with wind-related
losses
IIsabel’s winds at the low end of vulnerability damage curves,
with considerably higher uncertainty
Many claims outside the
windfield footprint
“The damage that resulted was not of a type that
might have been expected for the average winds
that occurred... there was a large amount of
structural damage resulting from fallen trees striking structures.” |
