A few things to know.

Do I need Weather Madness to use 4070?

No. Pro includes the weather tools, local forecasts, radar and published WDS briefings. Add Weather Madness if you want Henry’s forecasts and member community too.

I saw 4070 in a video. Can I just get the tools?

Yes. You can use Pro on its own, whether you found it through a forecaster, a friend or a weather map. Explore everything included in Pro.

What does the extra $5 include?

Weather Madness adds Henry’s video briefings, written forecast discussions and the Weather Madness member feed and chat. It is an additional $5/month on top of Pro after the introductory offer.

Is this personal, one-to-one forecasting?

The membership includes published forecaster forecasts for the areas they cover and a shared community. You can ask questions in the feed and chat; a personal forecast or individual reply is not included as a promised service.

Can I start the trial now?
