Keeping an Eye on the Storms

By Karen Richardson

The 2011 hurricane season in the United States churned up many severe tropical storms such as Irene, Arlene, Bret, Emily, Harvey, Maria, and Rina.

Meteorologists always track these tropical storms, and so do insurers and reinsurers. They use ArcGIS technology and data from Esri for location intelligence, which helps them accurately calculate risk in their coverage areas and make the timely decisions needed to help their clients recover from hurricanes and other catastrophic events as quickly as possible.

Hurricane Irene, which caused severe flooding and wind damage in states such as New Jersey, New York, and Connecticut last August, exemplifies why it is important to know the exact location of both insured properties and the intensity of the storm.

In this article, Esri insurance industry solutions manager Mark McCoy details how and why location intelligence with ArcGIS is becoming so valuable to the insurance industry.

Amica Mutual Insurance is one of the companies that uses ArcGIS to track major storms. Read Amica's story.
