About

What Chaseit is

Chaseit is a southern UK storm chasing community — chasers, forecasters and weather photographers across southern England, Wales, the Midlands and East Anglia who go to severe weather rather than away from it.

The site is the operational layer for that community. Live radar and lightning, a curated convective outlook, ADS-B-derived upper-air winds, soundings, chase-target rankings, and chase-day coordination for members. Post-event, it's the place reports get logged, verified against MetOffice warnings, and stitched into recaps.

We're not a media outlet, an emergency service, or a paid forecasting product. Forecasts presented here are guidance based on open data — your own judgement on the day still has to take the wheel.

Joining

Membership is approved by coordinators after a quick review. You can sign in with a magic link to start the process. Members get the chase planner, in-field comms, position sharing during active chases, and the full back-office.

You don't have to be a member to read the public surfaces or subscribe to digests. The forecasting tools, news, events calendar, member directory and storm reports are open to anyone.

Data & sources

Radar from the Met Office composite, lightning from EUMETSAT MTG-LI, soundings from open-meteo, upper-air winds derived from ADS-B, the convective outlook compiled by the Stormfront lens from Open-Meteo + Met Office UKV. Storm reports come from members and are exported in ESSL/ESWD format from the back office.
