U.S. Thunderstorm Insured Loss Trends,
1980 – 2013
Hurricanes get all the headlines,
but thunderstorms are consistent
producers of large scale loss.
2008-2013 are the most expensive
years on record.
Average
thunderstorm
losses are up 7 fold
since the early
1980s. The 5-year
running average
loss is up sharply

Homeowners performance in 2011 was severely impacted by
record tornado activity. Home insurers paid out $1.22 in claims
and expenses for every dollar they earned in premium.

Based on the HO-3 homeowner package policy for owner-occupied dwellings, 1 to 4 family units. Provides “all risks” coverage (except those
specifically excluded in the policy) on buildings and broad named-peril coverage on personal property, and is the most common package written.
(2) The Texas Department of Insurance developed home insurance policy forms that are similar but not identical to the standard forms. In addition,
due to the Texas Windstorm Association (which writes wind-only policies) classifying HO-1, 2 and 5 premiums as HO-3, the average premium for
homeowners insurance is artificially high.
Note: Average premium=Premiums/exposure per house years. A house year is equal to 365 days of insured coverage for a single dwelling. The NAIC
does not rank state average expenditures and does not endorse any conclusions drawn from this data.

Unusual Weather Pattern Over the US in
Spring 2013 Led to Low Convective Activity
Reasons for lack of tornado activity
during spring:
 Strong high pressure anchored
over the northeast Pacific Ocean
 Polar jet stream forced much
further north than normal into
Alaska before diving southward
across the eastern United States
 This pattern allowed cool Arctic
air masses to dive south over the
central United States, keeping
the atmosphere relatively stable.

What Do the 2013 Tornado and Tropical
Storm Anomalies Mean for the Next Years?
Convective Storms
 US Tornado season 2013 dominated by short term air pressures patterns
 No reason to expect another season like 2013 in 2014
 On the long term climate change most probably will increase activity of
convective storms, events like in Germany 2013 may become more
frequent.
Tropical Storms
 2013 hurricane activity dominated by unusual short term effects
- such short term effects cannot be predicted on a seasonal basis
- no reason to believe to see a repetition next year
- 2014 starts again with the odds of the current Atlantic warm phase.
 Typhoon activity will rise in the next years due to a natural oscillation
2013 a first indicator of this?
