PCT, 30. Asociación Regional IV – Plan Operativo sobre Huracanes para América del Norte, América Central y el Caribe (OMM-N° 1163), TCP-30
Las actividades regionales del Programa de Ciclones Tropicales de la OMM consisten principalmente en los programas que llevan a cabo grupos de países que actúan de consuno para mejorar sus sistemas de aviso. En la Región IV (América del Norte, América Central y el Caribe) existe desde hace mucho tiempo una acción colectiva cuyo objetivo específico es proteger a las personas y los bienes contra los ciclones tropicales violentos, que reciben el nombre de huracanes en la Región. La séptima reunión de la Asociación Regional IV (Ciudad de México, abril-mayo de 1977) estableció un grupo de tra ...
TCP, 30. Regional Association IV – Hurricane Operational Plan for North America, Central America and the Caribbean (WMO-No. 1163), TCP-30
The regional activities under the WMO Tropical Cyclone Programme consist mainly of the programmes pursued by groups of countries acting in concert to improve their warning systems. In Region IV (North America, Central America and the Caribbean) there is a long history of collective action specifically designed to protect people and property from the severe tropical cyclones which are called hurricanes in the Region. A working group, known as the RA IV Hurricane Committee, was established by the seventh session of Regional Association IV (Mexico City, April May 1977) to promote such activities ...
TCP, 23. Typhoon Committee Operational Manual (WMO/TD-No. 196), TCP-23 : Meteorological Component
The Operational Manual consists of the text and the appendices. Items included in the text relate to the Typhoon Committee agreement, in particular, basic information for executing meteorological operation, whilst the appendices contain national practices and procedures (it is felt that the Member concerned should have the right to be able to change without having to get prior formal agreement of the Typhoon Committee) together with detailed and technical information for meteorological operation. Information described in WMO official publications such as Manuals is only referred to and not i ...
International Workshop on Satellite Analysis of Tropical Cyclones (IWSATC-3): Final report
WMO, 2022In this report, we summarize the reported changes in TC satellite analysis techniques since IWSATC-I (2011) and highlight the continued development of existing objective analysis methods as well as the emergence of new algorithms.
Local Tropical Cyclone Precipitation Forecasting and Communication
This lesson introduces learners to the challenges in predicting and communicating localized tropical cyclone (TC) rainfall threats. The lesson discusses the key ingredients conducive for heavy TC rainfall, and the tools used by the National Weather Service to forecast it. Learners work through a TC case to practice interpreting precipitation guidance correctly and communicating the threat and impacts. The lesson also highlights the issuance of flash flood emergencies and areal flood warnings during TC events, and how to best communicate TC rainfall impacts for a local area. The lesson will tak ...
WPC Rainfall Guidance for Tropical Cyclones
This lesson introduces learners to the challenges in predicting precipitation associated with tropical cyclones (TCs). It also provides an overview of the deterministic and probabilistic rainfall guidance products issued by the Weather Prediction Center (WPC) to forecast TC-related precipitation. Learners work through a TC case to practice interpreting the guidance correctly and communicating the precipitation threat. The lesson also highlights the different interpretations of probabilistic products from the WPC and National Hurricane Center, and the need for collaboration between national cen ...
SatFC-G: Tropical to Extratropical Transition
This lesson uses water vapor satellite imagery from Himawari-8 to describe the typical extratropical transition of a tropical cyclone. The Himawari-8 imager previews comparable capabilities coming online with the GOES-R ABI imager. The lesson also provides a brief overview of subtropical cyclones and their transition to tropical cyclones. This lesson is a part of the NWS Satellite Foundation GOES-R Course.
Best Practices in Tropical Cyclone Briefings
Crafting clear, concise and effective messages focused on customer needs is a crucial skill in every decision-support situation. Tropical cyclones that threaten a coastline have the potential to inflict devastating damage to communities and communicating relevant weather information will assist decision-makers in their plans and preparation work. This lesson examines how to effectively prepare for the hurricane season and then focuses on how best to support NWS partners through meteorological briefings during tropical cyclone events. Basic familiarity with probabilistic forecast guidance is re ...

International Workshop on Satellite Analysis of Tropical Cyclones II (IWSATC-II), Report and Recommendations : final report
In this report, we summarize the reported changes in TC satellite analysis techniques since IWSATC-I (2011) and highlight the continued development of existing objective analysis methods as well as the emergence of new algorithms.
Use of Probabilistic Guidance in Local Tropical Cyclone Wind Forecasting
This lesson describes the role of forecasters in supporting emergency managers during tropical cyclones with a focus on the wind hazards. It provides an overview of the wind speed products produced by the National Weather Service, including how they are used to create local wind forecasts. Learners will practice interpreting probabilistic wind speed guidance and conveying appropriate wind speed information to decision-makers using projected scenarios of hazardous wind events. Developing messages for emergency managers and the public that include the potential wind speed, threat, and impact inf ...
Tropical Cyclone Forecast Uncertainty
This lesson introduces learners to the uncertainty and errors in forecasting the track, timing, and intensity of tropical cyclones. It provides an overview of how the National Hurricane Center’s cone of uncertainty is constructed, as well as its uses and common misconceptions. Learners will explore the influences of track, timing, and intensity forecast errors on potential tropical cyclones impacts. The lesson offers suggestions on how to communicate tropical cyclone forecasts knowing their inherent uncertainty. This online lesson is part of the Tropical Cyclone Storm Winds: Forecasting and Co ...
Determining the Onset and Risk of Tropical Cyclone Winds
This lesson introduces forecasters to the probabilistic guidance products used by the National Hurricane Center to assess tropical cyclone wind threats. It provides an overview of how these probabilistic wind speed products are created, their purposes, and how to interpret them. The lesson also provides practice in determining the total risk and timing for location-specific peak wind events. This online lesson is part of the Tropical Cyclone Storm Winds: Forecasting and Communication course.
Introduction to Climatology for the Tropical Pacific Islands
This lesson provides information on climatology—what it is, the factors that create an area's climate, and the sources and uses of climate information. Focused specifically on tropical Pacific islands, the content covers the key features influencing climate in that region and includes examples for four locations distributed across the tropical Pacific Ocean, both north and south of the equator. The lesson provides a basic introduction to tropical climatology intended for a wide range of users, from meteorology technicians, forecasters, and scientists, to those in industries or sectors influenc ...
Introduction to Tropical Cyclone Storm Surge
This lesson introduces forecasters to the physical processes and impacts of tropical cyclone storm surge. It provides an overview of the factors that affect storm surge, how it is measured, and the limitations associated with storm surge data.

Overview of Watershed and Channel Sedimentation
This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary pr ...
