The Third meeting of the Expert Team on Wind Waves and Storm Surges was held in Toronto, Canada. The Team reviewed the work that has been done since JCOMM-III (November 2009, Morocco), identifying follow-up actions, and updated the intersessional workplan. Main outcome of this meeting include the following:

• The operational wave forecast verification project would continue with extended application of the ECMWF web products.
• The Team will continue to work with ETMC in establishing the template for extreme wave data base, and provide feedback to the US National Ocean Data Center (NODC) which will host the database. The Team will also seek participation of Oil and Gas Producers Met Ocean Committee, and coordination with the GLOBWAVE.
• The Team discussed on the follow-up to recommendations at JCOMM Symposium on Storm Surges (2007, Seoul), including storm surge climatology. On this particular issue, the definition and requirements should be further developed, possibly until MARCDAT-III workshop in early 2011.
• The Team will continue to lead the WMO Coastal Inundation and Forecasting Demonstration Project (CIFDP), by Val Swailand Don Resio, and support the implementation of WMO Storm Surge Watch Scheme.
• The Team will continue to provide advice to the UNESCO pilot project for Enhancing regional capabilities for Coastal Hazards Forecasting and Data Portal Systems, led by Kevin Horsburgh and involvement of other Team members. The Team will also continue provide input to the planning of ESA Storm Surge Project (eSurge).
• The Team initiated work to update the Guide to Wave Analysis and Forecasting (WMO No.72). A table of contents will be completed by the end of September 2010. The Guide to Storm Surge Forecasting will be published after final review by the Team.
• The Team reviewed wave measurement related sections of Part II, Chapter 4, Marine Observations, of the WMO Guide to Meteorological Instruments and Methods of Observation (WMO No. 8). The proposed changes have been submitted and included in the version submitted to CIMO for approval. The meeting also reviewed requirements for the encoding of wave information in BUFR, and discussed the proposals by the DMPA Task Team on Table Driven Codes in this regard.
• The Team discussed on two Pilot Projects on wave observations, PP-WET and PP-WMD. Further input from the Team were delivered to the project steering committees.
• Following the request at JCOMM-III, the Team worked with ETMSS to develop proposals for inclusion of information on complex sea states in weather and sea bulletins, and subsequently for amendment WMO Manuals No. 558 and 471.
