Your feedback has been invaluable in identifying issues to fix and improvements to make. Since the launch of MAVIS on 24 March 2026, we've made various enhancements including:

• Improved log in experience.  
• MAVIS release notes webpage to keep all users up to date with new feature/improvements implemented on MAVIS. The web page is updated after every release.  
• New cloud base layer showing data at 500ft intervals at ground level.  
• 6 new base maps available.  
• Default base selection and tailored reports available to Offshore & SAR Helicopter Operators.   
• Improved printing functionality for ballooning forecasts and briefing packs.  
• 36 Aerodrome Table including RAG colour coding for all commercial customers.  
• Regional TAF, METAR and Warning lists.  
• Satellite map layers including Visible, Infrared and Snow False Colour.  

A more comprehensive list of features, fixes and enhancements recently released to MAVIS are described on our ‘updates’ page (accessed from the side menu of MAVIS).  

The feedback submitted to us by users of the service is reviewed daily and prioritised accordingly. Some items are quick wins and are easier to implement, whereas others require further investigation, testing, and consultation with internal Met Office teams, projects, UX professionals and with users directly. As such, they may take longer to deliver.   

Our next planned improvements include:

• Fog map layer
• TAFs for military sites.
• METAR Trends 
• Custom RAG thresholds for individual users.  
• Usability & navigation improvements
