- Feedback and Comments
The NHC will produce a set of updated storm surge probability graphics whenever a hurricane watch
or hurricane warning is in effect for any portion of the Gulf or Atlantic coasts of the continental United States.
These graphics will take approximately 30 minutes (perhaps more) to update on the NHC website following the issuance
of the NHC tropical cyclone advisories at 5:00 AM EDT, 11:00 AM EDT, 5:00 PM EDT, and 11:00 PM EDT (or 4:00 AM EST,
10:00 AM EST, 4:00 PM EST, and 10:00 PM EST).
These graphics can be found here when
advisories are created for an active storm.
