Plaincast is run by one person, Jonah Berg, and every channel below reaches him directly. There is no support queue and no ticket robot.
Report a bug or a bad translation
Open an issue at github.com/jonahberg/plaincast/issues. This is the fastest route and the one to prefer, because the fix and the discussion end up in the same public place.
A translation that misreads the forecaster is the single most useful thing to report. Include the office code and roughly when you read it — for example "OKX, Thursday morning" — so the issuance can be found. Discussions are replaced 3 to 4 times a day, so a screenshot of what you saw helps more than a link.
Report a security issue
Security contact and policy are published at /.well-known/security.txt, per RFC 9116. Please report vulnerabilities there rather than in a public issue thread.
Ask for a forecast office
Plaincast covers 68 of the National Weather Service's forecast offices — the ones covering the largest share of the population. If yours is missing, open an issue naming the three-letter office code and it will be considered for the next batch. Every covered office is listed in /llms.txt and /sitemap.xml.
Everything else
For anything that is not about the site itself — writing, work, or the other projects — jonahberg.com is the front door.
Two things Plaincast cannot help with. It cannot answer "what is the weather going to do" — read your local edition, or ask the National Weather Service. And it cannot change a forecast: every word on this site is the NWS's, and corrections to a forecast belong with the office that issued it.
