Local Surge Impacts Information (Text)

While the National Hurricane Center public advisory statements provide tropical cyclone related impacts on a regional scale, the local WFOs coordinate closely with the NHC to provide refined forecast products and warnings on a local level. Two of these products are the Hurricane Local Statement (HLS) and the associated Graphical HLS.

The HLS is a valuable product that can be used as a tool to monitor several different threats (not just surge) and potential impacts to your area. It includes:

• Counties, parishes, or cities affected
• Watches and/or warnings in effect
• Recommended precautionary actions
• Storm surge and storm tide information
• Present winds and the expected time of onset of tropical storm or hurricane-force winds
• Tornado, flood, flash flood, rip current, beach erosion, and inland high wind potential

Below is an example of the storm surge portion of an Hurricane Local Statement:

The State emergency management offices work closely with the NHC in assessing evacuations with respect to coastal storm surge vulnerability. The NHC updates SLOSH basins creating the MOMs and MEOWs which are ultimately used by EMs to drive the nation's evaculation zones.
