New Storm Surge Data

This release contains 2 new storm surge products. This video compares the products to help you understand when they can best be used. Complete release notes are below.


Potential Storm Surge: National Hurricane Center

Data Product Group: Baron API
Update Period: Every 6 hours

NHC Potential Storm Surge forecasts the potential depth of surge above ground level at a resolution as high as 30 meters. Issuance will typically be within 48 hours of tropical storm force winds reaching land. NHC Potential Storm Surge forecasts are only available for sections of a coastline being impacted by a storm. This is a reasonable worst-case scenario, with the values being representative of only a 10% chance of surge exceeding that forecast height above ground level.


Qrisq Storm Surge

Data Product Group: Tropical
Update Period: Every 6 hours

The Qrisq Storm Surge product forecasts the potential depth of surge above ground level at a resolution of 1km. This forecast is based off the ADCIRC Ocean Circulation Model, which takes a multitude of considerations into account, including a high-resolution model wind field. Qrisq Storm Surge forecasts are issued 5 days in advance of landfall and will cover the entire U.S. Gulf and Atlantic coastlines.

 You must display the Qrisq logo when using this product. The Qrisq logo will be added to your Graphics>Logos folder in Lynx during the upgrade.
