Aloft is a community weather forecasting project which lets anyone add their forecast to the system for specific areas on specific days.
This system is known as Crowdcasting.
The app lets you add a forecast up to three days ahead. There is no need to register or log-in and its simple and quick to use.
Make your forecast by highlighting the map where you forecast the particular weather to occur. The app then blends all the available forecasts together to produce the result, which highlights the areas of most significance - namely the areas which the forecasts all - or mostly - agree upon.
The app lets you add forecasts for electrical storms, high winds and snow. Over time this may be widened to cover flooding risk and other extreme weather phenomenon.
It must be noted that these forecasts can only be as reliable as those who submit them. The crowdcasting system is an experimental one, and we are aware of the flaws. However, we have several potential ways around these limitations, and will be implementing these in due course.
For the time being - enjoy the app and we hope you find it a useful tool for your forecasting and weather-watching purposes.
Thank you for looking/trying the app -
