Tornado and large hail threats in the Southeastern US this weekend

 In Event News

On Mar 17 & 18, severe thunderstorms produced at least a dozen tornadoes across the southeastern US particularly in Alabama, Mississippi and Arkansas. The threat continues today as the storm system moves toward the Atlantic coast. This quick moving system may produce some severe tornadoes and damaging winds to parts of Eastern Carolinas.

Assessing the impact

EigenPrism users can access the following quick links to immediately overlay the event footprints on their exposure:

The 24-hr hail swath provides maximum expected size of hail over the past 24 hours. This footprint can be used to provide an early estimate of where hail damage can be expected but does not provide the actual hail footprint.

The significant tornado outlook provides the region of 10% or greater probability of wind gusts 65 knots or greater within 25 miles of a point. A constant 1% of maximum intensity is assumed for damage estimation purposes.
