Some of the main things weather forecasters take into consideration are satellite images and different forecast models from various meteorological agencies. Here are some of the free tools that I found weather experts use daily in their work.

1. — global satellite images

  • You can choose to view any HD satellite images globally or in a specific country
  • Forecast, Model charts, Observation, Radar & Lightning

2. — Best visualization weather map

  • Great and easy to understand visualization for wind, precipitation, cloud and etc.
  • Can select any point on the map and compare the weather forecast between 3 models; ECMWF, GFS, NEMS
  • Has iOS app and customizable notification

3. Meteoblue — Free Multimodel Report

  • This is the only one website that give you multi forecasting model graphs globally for free
  • It will suggest you to see multimodel report if the reliability is low

4. — 3D earth wind map

5. U.S. Naval Research Laboratory — Tropical Cyclone tracking

6. Japan Himawari satellite

7. — Combine radar images from each country into world precipitation map

  • Animated precipitation map, easy to understand
  • Support 78 countries, update every 5-10 minutes
  • Has free application with ads and rain notification features

8. Digital Typhoon - Japan Typhoon Images and Information

  • Typhoon information and historical database
  • Himawari satellite images
  • AMeDAS data and statistical data

9. Meteomanz - Global SYNOP station, GFS, ECMWF Forecast

  • Historical global weather observation data from SYNOP station
  • GFS / ECMWF Forecast 8 days, 6 hours interval (no historical data)

One thing that you will be amazed is that some of these tools above are actually made by only one or a few makers. They are all weather lover and want to make it easier for people to understand and have access to weather information. So why not give it a try it could be a lot easier than you think.

If I know more I’ll keep adding it here. Thanks for reading and don’t forget to use these tools before you go out.
