@Korina We use the NAM model for exact severe WX impacts in middle USA. NAM is forecasting those saddened popup storms..hail..correctly for Denver USA. for off shore Wx..the GFS is good for the CARIBBEAN.

Let me think on a business model for you. If you would like? I am retired programmer now sailing into tropics with vessels helping in distaser areas. I volunteer with a group called International Rescue Group, and help all the time with Seven Seas Cruising Association. we sail about 5-10k miles a year in our own vessel, this year was in East Caribbean helping.
You have done an amazing job with your apps and hard efforts..
