## 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

## 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
