NHC on Twitter

The NHC presence on Twitter is a prototype to help decision-makers and the public receive notifications of the very latest on hazardous tropical weather systems. The addition of NHC's voice via Twitter services to the social stream is meant to enhance the ability of NHC and its partners to achieve their missions by building situational awareness, and allow for a broader reach of information to the public that it serves.

NHC has five twitter accounts:

Atlantic (NHC_Atlantic) & Eastern Pacific (NHC_Pacific)

These two mostly automated accounts are used to update followers whenever NHC has issued one of the following products for that basin:

  • A public advisory regarding a tropical cyclone (TCP)
  • A tropical cyclone update (TCU)

Each tweet contains a link to access the corresponding product on the NHC website. NHC also can tweet special messages at any time.


Storm Surge (NHC_Surge)

This account enhances storm surge forecasts by providing real-time reports and observations during an event (resources permitting). The feed will enhance preparedness and outreach efforts throughout the year, and provide news and announcements on updates to the SLOSH modeling system and storm surge decision support tools.

Tropical Analysis and Forecast Branch (NHC_TAFB)

The Tropical Analysis and Forecast Branch (TAFB), an operational arm of the NHC, is responsible for issuing more than 100 marine products daily covering millions of square miles of the Atlantic and eastern Pacific Ocean. This account highlights significant marine weather events and outreach programs provided by TAFB.


Director (NHCDirector)

This account is updated exclusively by the NHC Director, Dr. Rick Knabb.
