Hurricane Analysis and Prediction - Register at:

Noon-1 PM EDT, Wednesday, August 4th

Dr. Mike Brennan, Chief, Hurricane Specialist Unit, National Hurricane Center

The Hurricane Specialist Unit (HSU) of the National Hurricane Center maintains a continuous watch on tropical cyclones and areas of disturbed weather within the North Atlantic and eastern North Pacific basins. The HSU prepares and issues analyses and forecasts in the form of text advisories and graphical products, issues coastal tropical cyclone watches and warnings for the United States and its Caribbean territories, and provides impact-based decision support services for federal, state, and local government partners. HSU also coordinates with and provides watch and warning recommendations to other World Meteorological Organization (WMO) Region IV meteorological services. The HSU also conducts an extensive outreach and education program, training U.S. emergency managers, the media, and representatives from many other countries affected by tropical cyclones.


Wind and Wave Prediction - Register at:

Noon-1 PM EDT, Thursday, August 6th

Dr. Chris Landsea, Chief, Tropical Analysis and Forecast Branch, National Hurricane Center


The Tropical Analysis and Forecast Branch (TAFB) within the National Hurricane Center makes forecasts of wind speeds/wave heights and issues wind Warnings year-round for 10,000,000 square nautical miles over the Atlantic Ocean north of the equator to 31°N and west of 35°W (including the Gulf of Mexico and Caribbean Sea) as well as the eastern North Pacific Ocean north of the equator to 30°N.  These wind Warnings include tropical storms and hurricanes as well as winter storms, tradewind gales, and severe gap-wind events (for example, the “Tehuantepecers” south of Mexico).  TAFB provides these forecasts under the auspices of both the U.S. National Weather Service and the International Maritime Organization.  This presentation will review the analyses and forecasts that are currently provided 365 days a year, 24 hours a day, as well as our impact-based decision support services for the U.S. Coast Guard, which relies upon the National Weather Service for weather forecasts and briefing support.
