Your support is needed. Ads cover site operating costs, but investments are needed to bring additional features and app updates.

Turbulence Forecast is a unique website founded on a whim in 2005, and 13 years later it's grown into an indispensable tool to our 80,000 visitors a month. While ads support the cost of the delivering the site, investments for new functionality in the iOS app and website require a predictable source of revenue. Ads are not enough to bring you the additional features you want, which is why I am asking for your direct support. Gold, Platinum, and Diamond level subscribers receive discounted turbulence forecasts by email, Obsidian level donors receive unlimited free forecasts by email.
