NHC Publishes 2026 New Products and Services Document

Earlier this week the National Hurricane Center (NHC) published their “National Hurricane Center Products and Services Update for 2026 Hurricane Season”. This document includes more information on the forecast-cone graphics developments that I discussed yesterday. It also includes information on:

• Storm Surge Watches and Warnings, Peak Storm Surge Graphic, and Potential Storm Surge Flooding Map for Hawaii,

• Mobile-friendly front page of the NHC website,

• Updated symbology of disturbances in the Graphical Tropical Weather Outlook for which development is not expected,

• Annual update to the track forecast error cone,

• Experimental Graphical Marine Wind Warning.
