Terms & Conditions

Weather Relay, operated by Grady West Labs. Last updated 5 September 2026.

Weather Relay is an SMS service operated by Grady West Labs, a sole proprietorship. You text it a location and it replies with a short weather forecast. By using the service you agree to these terms.

No warranty, and not a safety system

Weather forecasts are inherently uncertain, and this service compresses them aggressively to fit in a single text message. Forecasts may be wrong, stale, incomplete, or unavailable. The service may fail silently, be delayed, or stop working entirely without notice.

Do not use this service as your only source of weather information for any decision affecting your safety. It is intended to supplement a forecast you already obtained and a plan you already made, not to replace either. You remain solely responsible for your own decisions in the backcountry.

The service is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose. To the fullest extent permitted by law, Grady West Labs is not liable for any damages arising from your use of, or inability to use, this service.

Who can use it

Access is by invitation. The operator maintains an explicit list of permitted phone numbers; messages from any other number receive no reply.

Messages you will receive

Every message this service sends is a direct reply to a message you sent it. You will receive one reply per request. The service never sends recurring, scheduled, promotional, or unsolicited messages.

Costs

Message and data rates may apply. If you send messages over a satellite connection, your carrier's terms for satellite messaging apply and may carry separate charges or limits. This service does not charge you anything.

Opting out

Reply STOP at any time to stop receiving messages. Reply HELP for assistance.

Acceptable use

Do not use the service to send unlawful content, to attempt to disrupt it, or to generate automated traffic. The operator may remove any number from the permitted list at any time, for any reason.

Weather data

Forecast data is supplied by Open-Meteo and the United States National Weather Service. Grady West Labs does not produce forecasts and does not control the accuracy or availability of that data.

Changes

These terms may be revised, with the updated version posted at this address.
