7. Steps to Produce MWW • Create Hazard grids as you normally would • Have CWF saved as a work file so MWW formatter grabs the synopsis • Run MWW formatter • Edit the Overview Headline and add the segment text as needed • Call to action statements should need little if any editing • Do Not edit or delete the CAP Tags. If CTA is edited…make sure CAP Tags are on their own line

8. Implementation • Testing to start ~ August 1st • Please note any problems in the shift log and fill out an STR • Product will be available on national WWA page • Product will be made available on local webpages (similar to MFM) with a PNS issued asking for customer feedback • Local offices can play product on NWR if they so desire • 7 offices for initial testing with others gradually coming online beginning Oct/Nov 2007 • Fall 2008 MWW expected to become operational at all WFO’s with marine responsibility
